Self-contained attachment for side mounting of radio antenna. Antenna Сі-Бі with your own hands: armchairs, materials, stages of work. Zv'yazok and antenna radio

Golovna / Zahist

For a robotic radio in FM mode, it is possible to improve the quality of the received signal in the 88-108 MHz band. It’s easy to look at the back, like replacing a standard antenna with an attachment of a different type - a dipole.

Self-made antenna for receiving radio.

A lot of types of primaries are made of roses for connecting a simple external antenna - as a rule, a built-in or telescopic rod. You can build a good FM antenna with your own hands for a small penny. For whom, one visit to the nearest store of state goods is enough.

The set of tools and details will be as follows:

See the antennas

Antennas for the FM band can be mentally divided into three types:

to live on the surface;
linear;
aperture.

The aperture is called the reversal of the antenna. Khvilyovі channels - tse, sooner, okremy vipadok designs z hvileyu, scho to live. The directories in their modules are arranged in such a way that the stench can be vertically polarized. Itself on the windy channel to catch a TV broadcast. The FM antenna allows you to pick up the features of the possible rotting.

Installation of a radio signal catcher

The installation of an external antenna of a horizontal type is based on the choice of supporting structures. On them, you can secure insulators with your own hands. One of the pillars of the maє buti is installed on the dahu booth. Її it is necessary to mark with rattling stretch marks. A tree of required height can be vikorated as a support to another. The insulators can be installed in everyday life for the help of steel cables.

Close the outer part of the FM antenna to the isolators. It is not necessary to give a great tension. Drіt skaєtsya, yakscho the temperature again to dosit is low, and you can spend viability for low temperatures. Roller blocks allow you to use inappropriate colivannya. For their sake, to spread the drota on another county, the vantage of small roses. You will be connected to the FM antenna, so throw it through the insulator and block.

The receiving part of the antenna is to be formed from one piece of homogeneous material. If you do not have a single wire, it is better to fold the FM antenna with four identical elements. It is necessary to clean and solder with tin. The equipment for vertical descent of the antenna is not a serious problem. Respect that the conductor is not guilty of interfering with third-party elements. Conducting the antenna with your own hands, following the fastening on a special winding station. Tse not to allow you to change at the wrong position in the windy weather.

As a place for installing an FM antenna with your own hands, you are surrounded, it is necessary to fix another design. Tse kіlka shmatkіv drotu, yakі mayut looked like a "vinika". With its lower ends, the stench will be superimposed on the cable. The ends of the darts can be filled with melted tin. The place of soldering is to be covered with superficial insulation at the sight of bitumen or similar material.

The room antenna, smashed with your own hands, will be the best option to replace the old catcher. Insulators are guilty of closing the middle of the room. Let's get closer to the stele to give a priority as if receiving a signal. Conductor is guilty of stretching horizontally or bending at the spiral.

Butt resonant loop antenna

Resonant frame antennas are successfully victorious by mechanics to receive short-range signals. In order to guide the directions of the reception of the signal, it is easy to turn the antenna into any possible area. The magnetic storage field of the radio allows you to receive the signal more clearly.

How to prepare a frame structure?

An aluminum hoop with a diameter of 77 cm and an internal diameter of 1.7 cm can be found in any sports shop. Plumbing pipes with a combined construction of metal and plastic work well. For radio, it’s also bad for the middle tube of a smaller (16 mm) diameter.

Antena Rakhmattulaeva

The design of the radio antenna is easy to reach.

This solution is a simple option, to take off the resonant antenna, and work on a wide range of bands. The straightness diagram will be number 8. Aluminum and midi antennas work approximately the same.

Visnovki

We propagandized to your respect the popular types of antennas for radio, which you can build with your own hands. The majority of such decisions can be easily made for the preparation of a booth, and the simplicity of their establishment will allow you to easily cope with the most complex problems.

Did you get the instruction? Share it with social networks and on the sides of your sites. Leave your notes in the comments for the sake of our koristuvachs.

In this publication, it is not about those how to supplement, but about those how to revise the result on the knee.
Deyakі radio stations, for example, popular Midland G5 pіddayutsya doopratsyuvannyam navit povnimi novelties. Ale, if you need additional control, otherwise you can get a good speech.
For primitive control, stitch the same primitive field indicator as a whole.
For this preparation, we need a sensitive indicator head up to 200 μA (bazhano), a pair of diodes, a piece of wire and a soldering iron with solder.
The indicator head can be pulled out of an old evil tape recorder, for example. Kurochiti robitnik especially I wouldn’t have lifted my hand Abo buy for example from chip and dip.

Diodes pіdіdut naprilad KD 419, KD514 (і vzagalі KD5XX), KD922, GD507, D18, D20 (in short - Germanic)

The scheme in me is stagnant like this, only simpler - without capacitors (it just didn’t work at that moment). Everything works well, reacts well to the fourth-villian shtir, and in the Yagi the arrow is placed behind the light.

Dovzhina drotu-anteni maє buti quarter, tobto. for 433-446 megahertz - close to 16.5 centimeters. You can not catch the millimeters, we need the tool not for accurate measurements, but for control of soldering. You can put in a cheap telescope antenna for 50 rubles and take off the cost that changes (and change the frequency control accordingly)

Do not forget about the polarity of the antenna when you die. Like an antenna on a radio - a stellar line - bazhano її trimaty with the antenna of the indicator and approximately at the same height, otherwise the attachment may not react. Also check the robot of the walkie-talkie for one second (before the rework that day)
It is even more convenient to use such an indicator to check new self-contained antennas. Sometimes, the soldering is rotten, or the contact is wrong, or else. And so - having directed the antenna to the indicator - and it is immediately clear that it is working. We won’t guess what for the width of the antenna (as it doesn’t work as a requirement) you can burn the transmitter

Pictures

photo of my indicator front and back.

There is a resistor on my indicator head, don’t pay attention to it (remember the back).

Because of this indicator, I have already caught a BNC rose on self-contained antennas, as well as a bad antenna on the Midland G5.

You can install a walkie-talkie in the car for various reasons. Tse mozhe buti future sleep is more expensive with friends at the entrance to the cars, or you can become addicted to listening to other people's roses at the car. Ale, basically, such a device is installed either by taxi drivers or by far-reachers. Be it a reason, an antenna for a walkie-talkie is installed for a reliable robot.

Such an installation, only at first glance, can be simple. In fact, there are some nuances here, as it is necessary to change the hour of choice, the preparation and installation of the antenna.

See the old priymalnyh outbuildings

There are two types of antennas for walkie-talkies in a car:

vrіzna:
from a magnetic base.

The stench does not revolt in principle. The main thing is that the size of the antenna for the radio is stationary, and with a magnetic base it is significant, it can be taken out or rearranged in another place.

Freestanding antennas

Name clearly what the stench is to cling to one mist. To that before him, how to install this attachment, it is necessary to respectfully think, de yogo to install, so that you don’t respect it, and the reception is good. The following fact is also wrong: the antenna for the radio in the car can be attached to the body that you carry. To counteract this postulate and, for example, put it on the hood, otherwise it’s a wing, so it’s on a fake mass, the efficiency of the building will be spent by 30-40%. Deyakі avtolyubiteley try to complete this system and try to pass the masu with additional wires to the body. Ale, all the same, a bad effect in such a way cannot be reached. Wanting sometimes and spratsovuє, but only rarely. As a rule, at the reception of such an antenna for a radio, it is still working normally, but the transmission for the help of such an outbuilding is even worse.

An important factor in the installation will be height. What is more than installations of the device, it will be more effective than a robot. For example, if you mount the antenna in the bumper of a car, the transmission range of that receiver changes by half.

It is optimal to install the antenna in the middle of the dash. Deyakі fahivtsi reconcile, with equal success you can install її on the bracket at the kutka dahu. But here are some moments, which are necessary to protect for additional installation. If the installation of a walkie-talkie is needed only for driving in the city, then the option of attaching to the bracket is suitable. Tse not vpline on the robot will fit at the link with it, so that in the place the effect of straightening through the additional fermentation will not be created. If this device is installed for long trips on the highway, then the installation of an antenna for car radios at the kutі dahu will be unacceptable.

Installed built-in antenna

Installing the antenna in the das, it is necessary to strengthen the space with an additional metal plate. This is necessary for us for the greater wealth of the day.

The canvas itself and the coil, which is held, are to be blamed, as far as possible, as far as possible from the vertical metal planes, which are stitched parallel to the antennas. The minimum distance between them is to blame buti 50 cm. This aspect should be taken care of when installing antennas for car radios, in vintage cars, among them.

Antennas with magnetic base

Antenna with a magnetic base, otherwise, as people call it, "magnet", you can win on any car. Ale є kіlka momentsіv, yakіh next dotrimuvatisya pіd іїї її vstanovlennya.

For more efficient work and correct adjustment of this attachment, you should also install it on the body that you carry.
At the same time, it is not possible to change the length of the cable to the antenna. Tse brought to the point of impossibility to fix it, or else it is in line with the deterioration of the robotic attachment.
It is not recommended to fold the cable around the bay, otherwise it can be unfriendly to stick onto the robot device. If the cable is finished, lower it is necessary, you just need to carefully lay it around the cabin.
The position of the antenna on the dash can be sufficient. Such a view is not too impressive to the point of roztashuvannya. And if I need to dismantle it, then the next time, if I happen to win again, then put the antenna on the same place.

Do-it-yourself radio antenna

The simplest option for this kind of car upgrade would be to buy an antenna. Ale, you can buti prepared it yourself. For whom you can follow the cover instructions.

Take a simple whip antenna for radio. You don't need more than a support.
Buy knitting metal knitting needles with a diameter of 3-4 mm.
Get the cat down. Vaughn can be on a 10 mm frame. For її correct ї roboti it is necessary to wind 44 turns of the wire PEV 0.41.
They gave the next soldering of the coils to the brass bushings. Tse allow to secure a good contact and create an additional structure construction.
After that, at the sleeve, it is necessary to attach knitting needles from the skin tip. It is important that the offending spokes were equal to the dozhina.
Next, adjust the SWR meter and adjust the spokes and coils.
We will then carry out the installation of antennas for car radios without intermediary.
Open up the bed.
Unscrew the standard antenna, unscrew 2 screws, remove the active power supply board and carefully remove it.
Solder a 50-ohm coaxial cable on the plate. It is important to keep order alive, masu to masi.
All seals must be sealed.
Carry out a coaxial wire under the skin, kilimok and lead to the walk.
Attach the antenna to the plate.

If all the details of the algorithm were correct, then the antenna for the radio was broken by its own hands. You can proceed to the next stage - nalashtuvannya. Ale, like fakhіvtsі stverdzhuyut, tse dosit folds that delicate process. This is due to various aspects: it is necessary to carefully put in soldering, the winding of the coil is also not easy to do correctly. Yak visnovok: a self-contained attachment can be made less for a prepared amateur. Otherwise, a good antenna for a walkie-talkie is not possible in such a way.

Antenna fitting

If the antenna is installed correctly and correctly, then it will require only a small adjustment. But a lot of motorists are skeptical about this process, thinking that this element of the communication system cannot be of particular importance for the operation of the entire device. I deeply pardon. In addition, the antenna will be correctly installed for the radio and the installation of the device, not only a signal to the receiver, but also a robot to the device. Moreover, in order to incorrectly tune the radio, you can harmonize not only the transistors of the output cascade, but also threaten the device itself.

Pokrokov's instruction for installation

The adjustment of the radio antenna may be dependent on the upcoming algorithm:

For a correct adjustment, it is necessary to use such an attachment as an SWR meter.
The process of customization requires work far from structures made of metal, concrete or wood. Bazhano, the trees were placed no closer than 15-20 m.
Dzhe bazhano avtomobil zupinity on a clean, equal and dry flat.
On the installation of antennas, you can install nearby other cars with antennas for walkie-talkies. Further, it is necessary to install the SWR meter according to the instructions, so that between the radio and the antenna. It is not possible to vikoristovuvat pidsilyuvach in tsomu.
Freeze with an attachment, you need to work on different channels and at different points. Docile to carry out this procedure in different networks. Tse allow to paint a real picture of the nalashtuvannya.
The next step is more important: next to know the indicator-minimum SWR, ideally, the indicator is guilty of adding 1, it’s important to write down, de vine of roztashovaniya. If the faults are switched at a frequency lower than the one indicated, it means that the antenna needs to be shortened. Vіdpovіdno, yakscho more - you need to wait.
The approaching crock will be fast, or the antenna will be lowered, fallow in the form of indications of the KVR attachment. Extending or shortening is the process of adding or, on the other hand, winding the coils from the coils, and not shortening the antenna with small pieces.
Then again, it is necessary to look over the indicators of the SWR meter. Repeat the procedure until the end, until the required result is reached. Some models don't even dare to reach the ideal display, but it's not scary. If the indication is taken, for example, up to 1.5, spend 5% more. Ration as a whole will normally be practiced for the indicator 3. As a pidsiluvach is built into the system, it’s necessary to lie, that the indicator-minimum is not guilty of overvising 2.

If all steps of the algorithm have been passed correctly, the antenna for the walkie-talkie in the car will be fine.

17.10.2017

Despite the wide spread of television and the Internet, listening to radio stations does not lose popularity. Ale is often like a receiver of a radio station for the shortest. How to fix it, it’s necessary to sort it out, what to pour into the reception, and how to improve the situation?

Do-it-yourself antenna for receiving a radio

In these situations, the world is about to be tongue-in-cheek, and this interpretation can be shattered by looking at those that have been established scientifically. Oskelki until this hour, one of these principles of work is not scientifically or experimentally confirmed, we do not include the selection of such products from our own office, and it is not recommended to unique them.

In the rest of the years, international organs imposed on the virobniks the rules of informing about the risks of electromagnetic vibromining when vikoristanniy or the superfluous medium, as well as the results of vimirivs. The rules that are imposed on virobniks are the same.

Trochy theory

For normal operation, whether it be a radio receiving device: a TV set, a stylish phone, a radio receiver, it is necessary to provide a minimum level of signal at its entrance, which will exceed the singing threshold.

So mind you can blame not only through the distance from the radio stations, but also in the minds of the place. Most of the stench is experienced by radio receivers on the UHF and FM bands, which is connected with the peculiarities of the signal width.

Choose a suitable and handy cord and an antenna, and that's all practical - only if you swear, you want to do some fun in the auto train. Antennas are not damaged, or with a magnetic cushion, and short ones. Usі z channels "on pіvdorozі". However, in the middle, in which the antenna is installed, if there are impersonal factors, if it can be inserted into the SR, it is important to turn the antenna over before turning on the radio. It is necessary to obtain a superior and accessible instrument of radio communication, which can help you to transmit communications between a store and a warehouse, between a warehouse and an vantage, then.

Set the frequency of these signals to 66-108 MHz. Radio wires of the same range expand in the boundaries of line of sight and even nastily go around the heights of the relief of the city, and in the city - high houses.

The line-of-sight distance can be calculated using this formula, km:

r = 3.57 (√h1 + √h2), de

r – line of sight distance;

h1 is the height of the transmitting antenna;

Theft from cars - evil. The police officers often clash with the idea that this is a great manifestation, like hundreds of people are suffering every day. Tse range of radio waves, with which ones you can consult. Zv'yazok є lawful and widely expanded in the whole world. Roughly kazhuchi, tse extensions of the way to exchange information about the traffic of the middle waters.

To win respect - the wines are widely victorious in Northern Europe and Lithuania. However, as the radio station is breaking out of Western Europe, it won't be obov'azkovo mate tsyu sitka. Use two types of antennas - with a magnetic pad or a bolt. Managed more efficiently. The main feature of the antenna is its price and what it is necessary, it is effective.

h2 is the height of the receiving antenna.

tipi antennas

The purpose of the receiving antennas is to ensure that the signal is received, to be able to transmit it to the input of the receiving machine. Fallow in the range of the antenna may vary in design and dimensions.

Types of antennas are tens of thousands of antennas, and some of them are the most sophisticated engineering spores, hundreds of tons and thousands of square meters in size.

The antenna dowzhina, which is lost, swells up and forms a throat around the antenna. As a matter of fact, this part wastes its effectiveness, because the shorter the number is more effective. The shards of the antenna's dozhina є vіdnoyu, it is recommended to reconsider, chi total selected proportions of the antenna with your car. An unperfected antenna wastes part of its potential, but the link becomes short.

The range of radio communication lies in the presence of rich components - the most important medium, possessing that to inspire weather minds. In such a rank, with a good possession, you can stand between the city, the forest and the vastness of the variability. In addition, it can vary in fallow land due to the activity of the sun or the weather. However, bad weather can reach 4 km, and wind damage can reach 15 km.

At the simplest point of view, with a primal antenna, you can have a conductor of movements on insulators above the ground. Electromagnetic whirlwinds, altering it, induce it in a new way, according to the laws of physics, change the voltage of a high frequency and transmit it via a feeder to the input of a radio receiver, where the signal is strong, from a new low-frequency warehouse, in the sound of a person.

Antennas can be divided into two types: straight and non-directional. Є classification for recognition: stationary and mobile. Ignorant of the difference in types and types, enforce the laws of arrogance, for which the stench is practiced.

Do-it-yourself antennas

Drotyan

You can use a radio receiver by blowing up a simple antenna with your own hands. Fallow in the first place, which range is recognized, її razmіri it will be necessary to correct.

The smallest antennas should be used for the FM band, so the frequency of the radio stations in this band lies in the range of 88-108 MHz, also, the length of the wind is L - from 3.4 to 2.8 meters.

Dovzhina hvili be it a radio station can be known for the formula:

L = 300000/f, de

L - Dovzhina hvili in m.

f is the frequency of the radio signal Hz.

The design of the dart antenna

Dart antenna is the simplest design for the FM band, and it can be used in booths with any material, such as reinforced concrete. Also, you can spread it on the streets, pulling between two pairs of laces or budovs. The height of the height plays a great role: for the increase in height, the efficiency grows. Also plays the role of antenna orientation - straightening at the horizontal plane may look like a sky.

If the majority of the FM radio stations are in the vertical polarization range, then the antenna can be moved vertically, especially if it is brown, it can be on the line between the receiver, the signal is even weaker. Tsya antenna vikoristovuvatsya on either the range of NE, HF or UKH, it is necessary to overthrow the rozmіri.

Shtirov

The simplest type of rod antenna is a vertical conductor, fastened to an insulator and one end of the connection from the receiver. Dovzhina shtyrya is guilty, but it is picked up in accordance with the range of whiffs that are accepted. On the right, in what zgіdno z s slednymi doslidami and rosrahunkami, the length of such an antenna is to blame for the equal quarter of the length of the frailty, with this efficiency. the maximum antennas will change for any other direction.

The line well accepts the signal both horizontally and vertically polarized, moreover, this type is easily implemented both in the stationary version, and in the mobile, for example, in the quality of a car antenna.

The design of the rod umbrella antenna

4 vibrators were added to the receiver in this design to improve the reception signal and expand the reception signal. If the antenna is not directional, then it will still receive the signal well from any direction. The height of the sky, like in the front slope, signifies the distance to the receiver. Such a design is dotsilno vikoristovuvat at the dacha chi silskіy mіstsevosti, less industrial transitions.

Designs for the place

At the time of the place, the best option for receiving will be the installation of a television antenna of the hvilov channel type. Її advantages in the fact that there is a state direction. Tsya power in the minds of the place is very important, that which allows you to choose directly with the least equal change.

A self-contained antenna with a thin channel is folded with 3 lines and fixed on it with elements: 2 passive directors, a loop vibrator and a reflector. Rosemary to fall in the range of reception. This design ensures high-yield reception at a distance of up to 50 km and more, which is a decent result for the FM band.

Antenna hvilyovy channel for FM band

Since the antenna may have an output of 75 ohm, it is permissible to connect the cable as a whole without intermediary to the narrow box. It is also possible to win TV antennas of the meter range with 3-5 channels, which at times are often left without work, the fragments of TV traffic "moved" from these channels to the decimeter range, to the satellite or the Internet.

SB-pairs (CB, "Ci-Bi") are called those that work in the civilian frequency range, and 27 MHz itself. Registration is not required for the selection of such an attachment. The frequency is subdivided into the so-called network of channels. At dawn, the development of radio communications was less than 40 channels. And then, after that, yak tsієї kіlkost became not vistachati, їх began to beat and designate with alphabetic symbols. In this rank, the correct alignment of the radio transfers the correct installation of the channels.

Taxi drivers and far-reachers are actively using radio signals as the best, lowest mobile phone calls. There is no need to pay the operator for a rozmov, deposits in the form of a cover. Ale, as a minus, you can call the surroundings the radius of diy, as well as the possibility of changing the code and the interest of the channel.

And if you correctly select and adjust the antenna for the walkie-talkie, then you can reach a clear stable connection on a wide range. Zvichayno, radius dії lie and vіd obladnannya. Here 5-7 km, and є models and more lower s 20 km. But the importance of a good antenna is often underestimated. Aje richo, in which case it will determine the range of the received signal. Don't hurry to buy a walkie-talkie, it's possible that such a price is called for by the presence of a large number of people not to get the necessary functions. And with the connection of the main antenna to reach the budgetary possession, you will reach the result no better.

Antennas for car radios can be divided according to the type of installation:

on vrіznі;
magnetic.

The vrіna antenna is mounted at the body. With this, when installed on the hood, or the wing loses its effectiveness by 30-40%. Install as necessary in the vertical metal parts, as well as stitching in parallel with the antenna support.

Magnetic antennas do not interfere with installation and, as a rule, they are victorious on passenger cars. On great vintage machines, stench can be expelled through vibration. Such an antenna for a walkie-talkie can be easily installed and known, transferred to another car.

And also antennas for car radios are divided by size:

For a long time, we shtirem close to 2 meters, creating the most powerful and stable sound.
Average view 90 to 170 cm, there may be a smaller coefficient of strength and work on a smaller width. Then the stench is good, that such upper crossings, like bridges, tree trunks, power lines, do not get stuck.
Short 65-70 cm, handy and not so memorable, but provide a short range to the receiver.

The most effective ones are dovgі vrіznі. Ale to build a good antenna, it is necessary to install and install it correctly.

Installed

An important factor in a good signal is the correct installation of the antenna:

Creep at the upper part of the body on a stable basis.
Installation on bumpers, doors, mirrors reduces efficiency.
Install vertically, unless otherwise specified in the instructions. It is necessary to install it under the hood, it is necessary to install the back, and then we will fix it. Himself in this order, and not set it up, but then heal it.
The surface area on which the installation is to be carried out may be larger and flat.
Try not to put on the hood and the trunk.
The antenna itself and the back-up cable need to be roztashovuvat yaknaydal in the dzherel pereshkod, for example, systems of zalyuvannya.

Nalashtuvannya

Before changing antennas for the radio, the setting can be changed. If you don’t rob it, you don’t take away the statements of the ostentatious ones as I accept it. Instructions for setting up:

Nalashtuvannya can be vikonuvatisya in the same minds as the operation of the car. Tobto, among other cars, and not in garages.
It is necessary to install the antenna on the car. Do not need trimati її in the hands of the vase.
You need an attachment, ranks SWR meter. Connect the cable with one end to the antenna, and the other end to the SWR meter in ANT sockets. Next, plug in the attachment to the station (trans port and station antennas).
Set the FWD/REF switch on the SWR meter to the FWD position, and SWR/PWR to the SWR position (for some models, this switcher can be used).
Click on the gear and set the arrow to the end of the scale with the regulator.
Set FWD/REF to REF position. Fix the displays of fittings. The ideal value is the whole unit.
Next, reduce the SWR sequentially from the highest frequency to the lowest.
If the minimum SWR value is at a frequency lower than the operating one, it is necessary to shorten the antenna. If so, then zbіshiti.

Possible next options:

The SWR is at least one of the grids below 2. This means that the antenna is working correctly.
SWR skrіz 2.5 - It is possible, here the contact with the body is improved. І perevirte tsіlіsnіst cable.
An SWR higher than 5 means the antenna is not working.

Antennas for portable radios are classified as follows:

Spiral wide-smoking - small longevity, low efficiency.
Dipole piece lowered - medium efficiency, ale pracyuє at high brightness on a narrow frequency range.
Dipole single-range - the most effective of representations, but may have a greater difference and work only in one range.

For your model of radio, you can choose the appropriate antenna for changing. It is possible to repeat and revise their show-offs by a similar rank. But in times of portable walkie-talkies, the meaning of the characteristics of a blast for a yak_sny zv'yazku on a distant stand.

These are the principles of choice, installation and installation of antennas for the radio. You can choose the type of type you want depending on the purpose of your choice and on which car the installation will be carried out. If you know good models of antennas, or the secrets of their installation and installation, it is obligatory to share your thoughts with the comments.

Hello everyone.
Oskilki recently became the master of the BaofengUV-5R radio, having bought the NagoyaNA-771 antenna at the same time for forum tips. Ale, the results of testing at a distance showed the same effect, with a standard antenna, with a bare, accept, by ear. Here I am thinking. That person from kim vdchuvav, brought me a self-contained quarter. We tried it again, the result was richly improved. Naturally, I drank yoga, what kind of antenna, from such materials I was crushed. It turned out, everything is simpler.
May such an applicator, a field indicator. Rozpovіv, like him koristuvatisya, and the axis zvіlnivsya evening for tasting.
We take those that are under the hand, the most important 75 ohm cable, we take the top shirt, then braided with foil, the central core in the shirt is left behind. A couple of different adapters and we start shamanism. For the first antenna, select a frequency of 145500, look at 60 cm, set the field indicator to three times more than the middle, and move a centimeter apart, freeze. Photo results. After that, as a virahuvave the greatest resonance, having mounted a new antenna already behind the old house. The same procedure was performed at a frequency of 433,500. Tilks of expanding antennas are ventilated 4 times. Axis yak. For those yakіst zv'yazku pokraschilsya rich in povnyannі zі regular antenna. For the whole hour that I had fixed the antenna, the Lord would attach a posterir, having fixed the alarm, on the Yaesu FT-817ND walkie-talkie, a couple of kilometers away from the station, and remembering the completeness of the signal at the reception.
Now put the antennas in the house, leave them for a more aesthetically pleasing look and put them in a heat, and you can test for a distance already with your own hands. So I’ll try to freeze the SWR myself, but the switch is still expensive.
If I’ve been robbed in a wrong way, I ask you to make corrections, set morals, while the indicator of the field is still in me.
Well, and the pictures themselves (if you take it on your phone, don’t be too stoked):
