    Hello,
    I'm planning to buy a Televes V ZENIT directional antenna with LTE filter (149201) and I have a question, does this antenna already have an amplifier / power supply in the set? Do you have to buy one?
    Transmitter: Opole "Chrzelice"
    Distance from the transmitter: ~ 56km
    Thank you in advance for your help

    The antenna has a built-in balun, an amplifier should be unnecessary at this distance.
    Why don't you think about buying an antenna that will also receive MUX8?

    Well, MUX-8 would also be useful. Any suggestion? I always thought that antennas without an amplifier in my area received poorly.

    Hello,
    I need help in selecting equipment for TV installation for DVB-T reception.
    The installation should look more or less like in the picture:

    One antenna on the roof, a splitter in the attic for both rooms, each room will have a TV set and two radios.
    Please help me choose a combo antenna, splitters, antenna amplifier / power supply.
    Transmitter: Opole "Chrzelice"
    Distance from the transmitter: ~ 60km
    Thank you in advance for your help

    The basic UHF 1-2-3 mux 8 muxs are transmitted from the Chrzelice transmitter, the mux 8 does not appear as a program from this transmitter, so the combo antenna will not be needed, only a separate one for another direction and a crossover - the antenna you mentioned is a high-quality brand product and supply its amplifier in advance without checking the quality of the received signal passively misses the point - there is a strange rumor in the nation that you need to add amplifiers to the antennas and the stronger the better - nothing more wrong - ALWAYS set the antenna passively and in the position of the best reception when it is not satisfactory we attach a low-power amplifier to the installation, because a strong amplifier will certainly distort the signal

    MUX-8 only from the transmitter on Mount St. Anna. Combo could handle it? are these transmitters too far apart?

    Dear colleague, you can not answer this question because you did not provide your own location, so it is not possible to judge whether these two directions coincide with the place where you want to receive these muxs - the principle of functioning on the forum is to provide data on your location, environmental conditions, etc. necessary data - rather, you qualify for a warning for breaking the forum rules

    I will add this to the topic of "amplifiers in the nation": to receive DVB-T you need a signal 10 times weaker, if you give the receiver input over 2 mV, expect trouble. And in fact, for the analog at this level, good reception started.

    Chrzelice is not equipped with a MUX8 transmitter - and I don't think they will - but note that from Góra Św. Anna, it is broadcast on channel 6, which is the same as from Koszty, Ślęza, Śnieżne Kotłów, Czarna Góra, Sucha Góra and Solina. Differences in polarization are definitely not enough, especially in Lower Silesia. Personally, I think this network configuration is wrong.

    Many of my friends living in Lower Silesia signal to me that they have a lot of trouble with MUX8, for example in Brzeg or Prudnik. The northern part of the Opolskie Voivodeship has a very good reception from Kobyla Góra near Ostrzeszów, this signal is stable even in Opole.

    And the lack of information about the location (it does not have to be an exact address, a town or a nearby intersection in a larger town is enough) as a "delicate attention" of the moderator.

    Do not take the information on the dvb-t map pages for granted, this data is only indicative and should rather be considered as a "wish list". Anyway, like all computer simulations.
    And do not give us a list of broadcasting facilities, many in this forum know these facilities from the foundations to the ends of the masts, some even sat on their tops.

    PS. I don't see much point in a combo antenna.

    .... And that changes things.

    Of course, there will be no tests, but MUX1 / 2/3 has to be checked from Chrzelice and Klepaczki (Węczyca Wielka near Częstochowa).

    MUX8: both directions must be checked, theoretically Góra Św. Anna is closer, but SFN on this channel can cause a lot of problems (mainly signal from Ślęza, received to Częstochowa).
    Z Węczyca - sheet 9 in VERTICAL polarization which requires a rather separate antenna. The advantage of Węczyca is that there is no other DVB-T transmitter nearby on this channel and the signal is of relatively better quality. The strength is very similar for Węczyca and G. Św. Anna

    MUX8 is from Góra Św. Anna in horizontal polarization, you have to remember about it when doing antenna tests.

    And most importantly: before each check, clear the list of channels in the receiver and set the scan to manual mode only. All vending machines in these conditions can confuse us quite a lot.
