    Today I got the antenna for installation as in the subject and I have some questions for you

    1. Is the item AND (VHF) should not be in front of the mast and the fastening B ?
    2. Is it normal that the elements C1 and C2 are not connected however with D [after plastic]?
    3. How, how and how to combine these elements?

    4. This is the symmetriser in this antenna, do you know / have opinions about it? I bought a few but I didn't see anything like that ...

    5. Am I right that they want to use the Opticum W-20 HD amplifier, it should be mounted only between the above antenna and splitter / splitter, e.g .: (3-way 5-2450MHz ZLA0636 CABLETECH)

    An antenna like an antenna. The digital signal will collect without any problem. Don't even target multiplex.

    There was no need to buy, take on such a "complicated" antenna.
    It has to be as in the instructions and everything.

    23 channel is hopeless, 21 probably too.

    "probably also" or just a guess and where are you? or author of the post? what is to express and what is suggested is such a statement from which the little interested will learn - as he mentioned the post a little higher - follow the installation instructions is the first thing - the second thing is even more important to install the amplifier but only when you find the best possible passive signal and when it will not be satisfactory only then you can connect the amplifier - the antenna is pre-assembled and it should be finally assembled as instructed in nothing to change because it is a structure designed and made completely the same as other such antennas are connected with plastic elements in accordance with the technical design in several in places I installed such antennas in factory versions and they work perfectly - no structural corrections are needed :D

    From this antenna by my experience is more powerful ATX 91.

    What do you after "stronger"? He has a different problem. He suspects that the manufacturer did not do, made construction errors. Very good (AX) antenna as far as parameters are concerned.

    The manufacturer answered my second question clearly and succinctly:
    Quote:
    "The main element of the antenna is a simple dipole (vibrator) with half the wavelength connected to the antenna cable. The other elements of the antenna are not connected, so they are called passive elements. The rods on the receiving side are shorter than the vibrator and they are called directors (from direct - give direction), and rods on the opposite side longer than the vibrator are called reflectors (reflects waves). "

    And what new things did he give you? Everyone who has an idea knows what, what for, a dipole, director, reflector. The antenna has such a structure and it works and there is no reason to think that it is not connected. So it has to be. You had to buy Yagi and you have everything connected there.

    Koeldzy I have a question about this antenna I have mounted in such a way that is horizontal polarization exactly yes and this antenna is no different:
    Antena DVBT OPTICUM AX1000+LTE COMBO UHF-VHF: Installation Questions, Elements C1, C2 & Symmetriser
    and this polarization applies to the UHF and VHF band ?? because this is a combo antenna or a change to vertical polarization, i.e.
    Antena DVBT OPTICUM AX1000+LTE COMBO UHF-VHF: Installation Questions, Elements C1, C2 & Symmetriser
    will also change polarities to UHF ?? is it only the change in VHF polarization and UHF will stay horizontally further and Mux123 will be stable so far and only the Mux 8 reception will be improved because it transmits vertically from this transmitter as it is with this antenna colleagues?

    I did not ask in my only connected to this topic because it also concerns this antenna and I did not want to write a post under the post or conquer the topic so Sorki :)

    and as for the subject, i.e. VHF is responsible for this final oblong tube and these two short ones that come out of this plastic "box" which connects the antenna cable so they are only from VHF and they have no impact on the work of UHF, UHf is in itself level yes and it is certain ?? exactly with this antenna model because these ax1000 are already different versions I have seen and I have exactly the version as in the picture.

    Ok, thanks, Koledo, it's black magic for me with these antennas :)

    How did you not ask? You asked and I told you ...

    This "X" is a UHF dipole on mux 1-3 and is to be horizontal, and these rods are a VHF dipole and are to be vertical.
    _kli_ wrote:
    If you leave "X" horizontally and give the rods vertically, the antenna will be adapted to receive in two polarities. But will it cope - I won't tell you that.

    ... and additionally I pictured it with a picture.
    And you like "infidel Thomas" are still delving into the subject - here and on the Emitel forum.

    Changing the VHF polarization does not affect UHF polarization.
    You set the VHF vertically, UHF stays in horizontal polarization
    Why don't you ask in your subject and only do '' trips ''?
    And why do you answer knowing about "trips"?
