    Hello,

    I have the nearest transmitter within 2.2 km, unfortunately the facade of the building does not allow the installation of an external antenna. Three-story blocks. I am going to buy a room antenna.
    Can you tell if such an antenna will work when you live close to the transmitter? Can I return the antenna if it does not fulfill its purpose?

    greetings

    Regarding a potential return, you must ask the seller when buying. In general, room antennas are a lottery and almost all of them have built-in powerful amplifiers - 2.2 km from the transmitter it can be a problem. There is no way without a try.
    Check out ASP-4 Dipol (half mesh).

    Hello,
    when it comes to the EC4 chimney in Łódź it may be a problem. It is a powerful transmitter and "blows" 100kW on each MUX. And as Adi01 rightly pointed out, almost all "maids" are wires with an amplifier. Maybe something small and light for the balcony, to the railing or to the window?
    Mały Dipol 3-el / 21-69: http://www.dipol.com.pl/antena_telewzyjna_dipol_3-21-69_dvb-t_uhf_A0315.htm
    or Digit passive: https://www.telmor.pl/Katalog-produktow/Anten...T-DVB-T/DIGIT-i-DIGITactiva-LTE-PROTECTED-SAW with LTE filter. It works well in conditions of dense development.

    Both antennas are only for Mux 1-3, not for Mux 8. If the antenna is supposed to receive all muxs, then something like this: Link (version without amplifier). If it is not possible to mount it to a balcony railing or in a window recess, you can add a stand and there will be a room antenna.

    And where did your friend read that it is about MUX8?
    The EC4 chimney in the boat is only suitable for MUX1 / 2/3.
    The proposed antenna is ok, but on one condition, all MUXs from one direction. In Łódź, this is rather impossible.

    You must be erratic. Barczak's antenna is a UHF / VHF log-per, while the Telmor you suggest is a UHF log-per hidden in a plastic housing.

    I am consistent and I keep asking what MUX8 has to do with it, since it cannot be received from EC4 anyway? (yet). Who needs such a "barrel" (and still at home on a rack :wink: since he will not use half of it (VHF).

    The author of the topic was given several options / possibilities. Now he has to decide for himself what he will do - if he wants to overpay for a fancy housing, it is his private matter.

    Of course you are right ... well there is a choice.
    One note: if we are dealing with a series of reflections, a directional antenna with a low half-power angle is not recommended.
    Reception of TV signals in densely built-up conditions is quite a challenge, and from the room level in the apartment ... special.
    Room antennas for DVB-T reception are a lottery, the success of which depends on many unpredictable variables (ignoring the fact of their construction - wire + amplifier).
    In general, the reception in the room itself is in a sense a misunderstanding, although I admit that sometimes it works. But the multiplicity of conditions (type of walls, floor of the room, location of windows in relation to the transmitter, size of windows, type of glass (technology), number of furniture) as well as the distance of the transmitter, its power, ... all this makes success difficult to achieve. it is definitely not permanent. Let's not forget that this "unfortunate" signal must first get into the room somehow, and then, after repeated reflection, be lucky to get into the antenna ...
    External antennas should be used wherever possible, i.e. almost everywhere.
    In the micro scale (room) it is easier to change one parameter - and the whole puzzle will collapse, e.g. moving a wardrobe or a new piece of furniture.
    On a macro scale it is more difficult, but also possible - they will build a house outside the window or the tree will grow.
    Antennas with a wider "field of view" (large half-power angle) have greater possibilities of receiving the signal from reflection - you do not need to precisely set the direction, which in the conditions of the proximity of obstacles (dense buildings on the estate, street) is an important and beneficial feature. I have already written about the reception in the rooms.

    A bow to the gentlemen. Thank you for the information.
    The solution turned out to be very simple.
    My apartment is on the top floor of a three-story block. The transmitter is basically covering the gable wall. I bought 5 meters of cable, put on a male plug, on the other side I removed the insulation at a length of 30 cm, folded the metal braid in half, discarded the silverware, insulated it, pulled the cable behind the shelf and picked up about 25 channels even in bad weather. I was lucky. Have a nice day.

    Well done, a Pole can, ... in some cases, the proverbial nail is enough for an antenna :D
    By the way, what about the quality? (MER, BER). Nothing "frames" or pixels? If not, then happiness was exceptional.
    Congratulations.

Topic summary

The discussion revolves around selecting an indoor DVB-T antenna for a location in Łódź, situated 2.2 km from a powerful transmitter. Users express concerns about the effectiveness of indoor antennas due to potential signal interference in densely built environments. Recommendations include the ASP-4 Dipol and the Mały Dipol 3-el antennas, with considerations for their ability to receive multiple multiplexes (MUX). The conversation highlights the challenges of indoor reception, emphasizing that success can vary based on numerous factors such as building materials and antenna placement. One user shares a successful DIY solution using a modified cable to receive 25 channels, demonstrating that practical experimentation can yield positive results despite the inherent unpredictability of indoor antennas.
