Baofeng UV-5R Antennas: Best Options Under 200 PLN for Increased Range & Stationary Use

I do not know if the topic has already been, I am completely new here, but I would like to ask what antenna I could buy for a maximum price of PLN 200 to increase the range of this radio? It could also be a stationary antenna.

Well, you have to start whether you are looking for a mobile or stationary (some portable versions), we already know the budget. It's pretty cool.
A few more questions arise, do you have manual skills and can you do it yourself? Or are you looking for a ready-made product.
Please write where you live. Block or detached house, city, province, village, what are your options for mounting the antenna, where do you want to use it? What transmissions do you want to receive (service messages, NOAA, ISS, or PMR own communication), i.e. from what band, 2m or 70cm? (144 or 433 MHz)

Make it so for reception (even from the cosmos).

The cost is low and a lot of fun.
If you are interested, I will give you more information.

Radiokiller showed a great project, but the author of the topic should answer the questions, because maybe he only wants to buy due to the lack of opportunities for handicrafts.
In addition, the antenna must be converted to a given frequency, because it is rather not broadband.

Convert - as much as possible. If you have already assembled yours, try to pick up something 70 cm long. You will be surprised positively.

I live in the countryside, I can mount this antenna on the roof. I am looking for a ready-made product. I would like to listen to the services, mainly the fire brigade. I have about 15-20 km to the driving position.

If you want to listen to the guards, start with finding out what frequency they work on, because this will determine what the antenna is needed (if only this guard is directional, if something more is already omnidirectional), in the sense of how to tune it, some designs just need to be shortened but it is worth starting from this to check if the radio is catching any messages up close.

I would prefer omnidirectional, so that other services could also be heard. Well, as far as I know, they work on VHF probably from 148.5MHz to 149.5MHz. On the original antenna, it does not catch any messages from the control station.

How long have you been listening to find that you are getting nothing? Don't think that they are broadcasting something over and over again. Tune the radio to their frequency and wait until it burns.

Let's not make jokes, it is obvious that they are not transmitting anything all the time, but when the car leaves and I hear transient noises, it is obvious that something is wrong with the antenna. Unless I'm wrong

I'm not talking about jokes. I waited half a day for the control room to answer. On the other hand, on Baofeng, I set the frequency of the stationary radio at work and being 5 m from the antenna I will not receive anything but pops - coded. This may also be the case with the TSO or PSP in your city.

It is not like that, because I know that there are people in my area who can listen to it without any problems.
Going back to the topic, you are able to recommend me some nice external antenna for this radio. And one more question, can such antennas, about 40 cm from Nagoya or similar, be attached to a mast outside and connect them to the radio with a cable? Can they work outside?

There are nagoya car antennas on the cable, look for alle ....
I have no experience with booths.
I will only ask which antennas people in your area pick up on.

On the basics, but I don't have such a budget for them.

For my 144Mhz car I gave less than 100 PLN, the length of pi times the door 1.6m with the handle.
When you buy one, you change the mount for a mast and you have a good omni-directional one, you can always shorten it slightly (according to the wavelength formula). These 40cm antennas are good for a backpack or a pocket.
You can still look for the so-called J-tki project. You can make a symmetrical 300ohm cable or pipes, there are many designs of such antennas, even on the electrode, perfect for a mast.

Can you tell exactly what model do you have of this car? And at what distance do you manage to listen?

I also tried to make a half-wave dipole from 2 tecoscopic antennas. He can do it too, PLN 12 is not a fortune.

When I put it on the 6th floor in the city center, I caught all the services, but the sport gets boring quickly I also made this dipole from 2 telescopic antennas, I had lengths to which bands (services) and it was doing very well for a few zlotys spent on 2 antennas.
I have to look for what antenna it was, because I have already had a few years, I also bought one for the 70cm (433MHz) band, both for a magnetic car holder (easy adaptation to a stationary or a mast).

Hmm, I am wondering if I will attach this car antenna about 5m above the ground, will it allow me to listen from these 15-20km

Can you give us this "wavelength" formula?

Friend @ c2h5oh deigns to joke, but take it easy:
We calculate the wavelength as follows: Y = C / f, where
Y - Wavelength [m] C - speed of light [300,000,000 m / s] (300,000 km / h)
f - Frequency [Hz]
Having a wavelength (of a specific frequency), and an antenna of a specific length for a given band (half-wave, 5/8 or quarter-wave, etc.) and knowing the wavelength, we can tune the antenna by shortening - you have to be careful because it cannot be extended - sometimes some cars allow you to minimal correction because instead of physically shortening, you can hide it a bit in the socket where the dipole rod is inserted.

Below is a link to the calculator of a given wavelength (frequency)
http://ekalk.eu/flt_pl.html
and on its basis it is possible to calculate antenna lengths for 1/4, 1/2 or 5/8 wavelengths.

Easy to build GP 1/4 ? antenna.
The length of the elements should be selected according to the given band.

Thanks for the offer, but like I said, I'm looking for a ready-made one.

Google, phrase for example: "baofeng uv-5r external antenna".

I do not "deign to joke". When advising someone and "using" a formula, it would be necessary to provide a fairly correct formula.
I do not know how many times the formula for the dipole antenna was given on the electrode.
Let me remind you: 300 / f [MHz] / 4 * k where k is the shortening factor.
Why / 4?
Because it concerns the 1/4 ? dipole. Since you write about half-wave or 5 / 8? antennas, why don't you mention powering such antennas (matching)? It's not like you write "you have a calculator, count the length and you have a 1/2 or 5/8 wave antenna. You still need to adjust it to the radio.
The 1/4 ? antenna is the simplest solution. For GP antennas, remember about the angle of the counterweights (135 °).
It should also be remembered that Baofengs with an external antenna (especially with higher gain) simply clog up.
It is enough to read about amateur built outdoor antennas. It is on the electrode and on the Internet "from the subway" and the topic returns like a boomerang every few months.

I have not noticed. J-ka two-lane at the height of 8m. Visibility of antennas. Distance approx. 150-200m, two masts on one antenna for approx. 170 MHz, several dozen meters further antennas for approx. 148 MHz.
When receiving the station, even from the same band several channels up / down, I did not notice any clogging. Baofeng UV-5r.

Gentlemen, do you think the SIRIO GP-3e Antenna will be good for this uv 5r baofeng? If I connect it to baofeng with a 15-20m cable, will you not need any amplifier?

Amplifier not necessarily, but with such a distance, first of all, a good antenna cable (50 ohms), something like H155, and better H1000

As for the antenna, quite decent, but you would get better performance on a well-made J-board, at the cost of materials for half the price of this Sirio.

Okay, one more question. What ends for this cable do I need to buy to connect this SIRIO GP-3e Antenna with uv 5r baofeng?
