    Hello all.
    Once I bought an ordinary normal room antenna.
    However, there is poor reception to catch something good in DVB-T tropo time or an analog signal from Kaliningrad.
    I am from the vicinity of Władysławowo and I have a range of 135Km to Kaliningrad.
    With such a small tropo one can say the marginal signal obtains the quality of the visible snow-covered channel sometimes with voice but poor visibility of the image.
    So can you tell me if there is anything I can do to get a better effect?
    I made my modification in the same way as in the pictures, which improved the signal quality a bit, but I would like to change it even more effectively to get a long range of up to 150km or more.
    Can you advise me on how to convert it to get a better signal effect?

    Here are the photos of my antenna that I have converted.

    I would like to add that sometimes almost every day with this modification of my antenna it can catch such a reception from Kaliningrad almost every day in the evening.
    I'm upstairs and the antenna in the room will catch this reception



    And if I put the antenna on the roof in the right direction, it can get such a reception from Kaliningrad almost every day.




    So I need your help what to do and how to convert it to get a better effect.

    Invest in a directional antenna with a good profit. What you did won't survive a stronger gust of wind, or it will fall apart when a bird sits on it. The tape you stuck it all on will fall apart when exposed to UV rays.

    This antenna only holds on one side with a tape because it moves a little to the sides and this is how it is twisted and attached to the antenna. I tested and it holds quite firmly so that the bird can sit on it calmly.

    And what kind of antenna would you recommend with a good profit?
    I am thinking of buying a broadband mesh antenna like in the picture

    or plain without yagi.

    And when it comes to the directional line, I am not sure which one because I am looking for one with the longest range in kilometers.
    And would it be good with a gain of up to 46dBi?

    And the antenna plate I would buy

    And if I buy a broadband or directional antenna and an antenna plate selected by me, would I get good signal quality?

    You will get the answer to this question when you do what you wrote. I suspect the conditions are elevated and you have a picture. It should be better, but there is no guarantee.

    After all, the range reaches Kaliningrad via the Baltic Sea, so there is no area on the way.

    I know that I would have to test a broadband and directional antenna,
    just throw the money for them, the antenna needed with one of them is also a waste of money as one of them does not serve well as it should.
    As for this plate, which I gave in the link, it has a range of 180km and I used to have this plate and I know that it served me functions as the analog in Poland was.
    So which Antene is best to buy for you?

    Coming back to the question of whether to rework the pictures on this antenna in the way I have given below.

    On Picture by A.
    Improve DVB-T Reception & Analog Signal: Room Antenna Rework for 150km+ Range near Władysławowo
    Currently, I am connected so that the wires adhere to the main wire.

    On Picture B
    Improve DVB-T Reception & Analog Signal: Room Antenna Rework for 150km+ Range near Władysławowo
    In picture B I made a diagram that a pair of wires will be connected from the R to L channel without adjacent the main wide wire through which the stream flows.
    Of course, I will add that the connection will not be as crossed as in the picture in the middle between Wire L and R, only the connection will look in such a way that on Wire L there will be 3 wires adjacent and 3 wires of wire R will be along the line of the main wire L will not be adjacent at all the way when they will be connected, and then the other way round from the main wire R connect 3 wires to wire R and then 3 wires will not be adjacent to the main wire R, and along the main line R the wire L will be led to the wires.

    On Picture C.
    Improve DVB-T Reception & Analog Signal: Room Antenna Rework for 150km+ Range near Władysławowo
    Picture C looks like a diagram similar to picture B, except that the main wires R and L will be completely free of streams and isolated from wires. And the connection will look like picture B only without the main wires.

    Question...
    Which scheme do you think would be the best A, B or C solution?
    I would like from your solid advice on the schemes that I have written for you.
    Thank you very much in advance for your help and advice.

    I understand.
    Only that this board has 45dBi as he writes and that it has Application: 90-180 km from the TV transmitter.
    So out of all the boards, the SWA-9701 is the best amplifier.

    Added after 8 [hours] 7 [minutes]:

    Someone of you will help me choose a good diagram from pictures A, B, C what did I give above?

    Buddy, you don't write anything about the dimensions of the antenna. Remember that the antenna must be matched to the frequency of receiving or transmitting. No antenna made "by eye" can work properly.
    On the other hand, when it comes to the popular amplifiers you mentioned, let me write this: paper will accept everything. The gain of 45, even 60 dBi, is pure fiction, the fur seller does not have to be a furrier, in electronics it is exactly the same. "The seller said that, I bought it." There are a lot of such statements.
    You have to buy or make a 5-7 or 9-element 223MHz antenna, plus an amplifier, but with a real gain of about 18-22dB and you can expect effects. If you look around, maybe you will find an antenna from the 90s for the "first program" and an amplifier for such an antenna.
    Successful attempts.

    But no one knows your terrain conditions and no one can tell you remotely, buy this or that.
    The antenna is selected on site, the same applies to the amplifier - it is selected experimentally on site, depending on the signal already obtained.
    You have to spend money, buy a dozen or so models of the amplifier and amplifiers - put them together and choose them one by one, which will give the best effect.
    It cannot be done otherwise.

    First, my friend, think about what you really want to receive from Kaliningrad.
    Considering the frequencies of the stations transmitted from this transmitter and their powers, you need several directional antennas for individual bands. One will not do the trick.
    To make an antenna with a "range" of 180 km from a maid and it is not known what the challenge is. By the way, I remind you that the "range" of the antenna depends on many factors - incl. on the visibility of the transmitting and receiving antenna (terrain topography), its energy gain, possibly amplification, transmitter power, polarization ...
    Here on the forum one of my colleagues gave an attachment: List of transmitters and frequencies of analog TV channels: Kaliningrad, Lviv, and approximate ranges. I advise you to read it.

    The best investment is an antenna dedicated to one frequency. For example, if it is designed for 222 MHz (Rossiya 1 channel), this channel will receive the best. A colleague gave a calculator useful for assembling such an antenna for a specific frequency. If done well, it will give a better result than any other antenna or amplifier. I myself wonder about such; to pick up a tropo from Ukraine.

    Thanks to everyone for your help.
    The case helped in such a way.
    Purchase of a mesh antenna and SWA-9701 amplifier and suspension of the antenna 8 meters from the ground.
    When there is a tropo, the improved effect may not be the maximum, but it is better than at all, even when there is no tropo, the Russia1 channel shows signs of life.

    Here is a video of how it works when there is a moderate tropo for those interested




    Of course, he also adds a picture of how I have myself to the Kaliningrad transmitter.

    Do you have any ideas on how to improve the reception permanently?

Topic summary
