Connecting Dual Antennas to DVB-T Decoder for Multi-Direction Broadcasting Reception

Hello. I would like to receive programs on one decoder from two different broadcasting directions. How to connect two antennas to one dvbt decoder.

And google "TV reception from two antennas".
The guiding question is? What bands, what channels? It all influences the decision of what and how?
Greetings.

Through the UHF / UHF crossover, but it is better to buy a 2xUHF / VHF crossover already, under the VHF it will be possible to connect a third antenna on MUX 8.

And can I ask for help? Some pic. What would be the best and that the signal would be without noise.

Hello

As my colleagues suggest and you can additionally try it with an antenna splitter, e.g. such as https://dvbsklep.pl/pl/p/Rozgaleznik-TV-dwudrozny-R-2-Signal/122

This is the simplest solution but:
1. It transfers frequencies from 5-1000Mhz, that is, everything in this band, not only programs.
2. Has a short circuit to the power (DC) of the antenna.
In summary, it can be used, but as part of the tests and if the antenna has power, the splitter must have one of the branches intended for DC transmission.
This is how the proforma wwsplitter can be connected inversely, i.e. to IN = DVB-T tuner and to OUT = Ant.1 and Ant.2.

It depends on which transmitters the signal will be received from.

Buddy, I wanted to connect two dvbt antennas, each directed in a different direction of broadcasting, under one dvbt decoder and one tv

And when it comes to transmitters, it is. One direction, Lodz, about 50 km, the other, Warsaw, 120 km. And I would like one antenna to direct the direction of Lodz, the other antenna to Warsaw and connect these two antennas to one dvbt decoder and a TV decoder. I have a set-top box built into the TV and I have this idea. The antenna in the direction of Lodz will be connected to a set-top box and TV and the antenna in the direction of Warsaw will be connected directly to the TV. The point is for me to receive more dvbt programs on one tv because depending on which direction the antenna is directed, there are other programs.

I can see that my colleague did not read the above-mentioned posts carefully!
In short: transmitters transmit with different power, at different frequencies, the antenna has or does not have an amplifier, gsm antennas located nearby can introduce interference, etc.
The crossover you need to buy depends on the above information.
I suggest you go to the nearest RTV store where they have antennas and crossovers, splitters and simply talk to the seller, he should advise something.
Although it may be different - few sellers install antennas and they lack practice.

"And as for the transmitters, then. One direction, Lodz, about 50 km, the other, Warsaw, 120 km. And I would like one antenna to direct the direction of Lodz, the other antenna to Warsaw and connect these two antennas to one dvbt decoder and a TV decoder.

Dude, if you have a TV set with a set-top box, why do you need a separate set-top box?

Without checking the strength of signals from the directions you are interested in, it is difficult to give advice,
The crossover introduces damping, maybe you need to provide a crossover with an amplifier.
You can use one for checking, the cost is low.
ANTENNA SWITCH ZA-112Ms (Z1005)
It has an additional input on VHF / MUX 8 /.
We have two antennas installed / direction Gorzów and Śnieżne Kotły / and with this tuning, the decoder tunes all channels from both antennas, then leaves only those that do not double when recording, i.e. the regional TVP Gorzów Wielkopolski adds us to the package broadcast by Wrocław . It's not like I have two TVN, two Polsats, etc.

That's what I mean. For example, the antenna is directed to Łódź, there are programs from Mux 1. The antenna is directed to Warsaw, there are programs from Mux 2. For example, on Mux 1, no Tv Warsaw, such an example, so if I connect two antennas to one decoder, I will have this TV Warsaw. I just mean how to connect so that there is no loss in signal transmission. I know that the programs will be duplicated, but others will come with mux2.

To my friend helazby. Well, I don't really need a decoder. I was just wondering how I could record several antenna signals on one TV from several, or exactly two, antennas directed in different directions.

Added after 6 [minutes]:

To a buddy. Well, this is what I mean when you write two antennas - the direction of Łódź and the other direction of Warsaw, so that the programs that Warsaw broadcasts can reach me, they do not have to and should not double. One TVN, one Polsat and other programs from the Łódź antenna, and TV Warszawa is coming from an antenna directed at Warsaw, which is not in Łódź.

Such a thing, for example, and the way of connecting

Thanks to everyone for your help. I think I can handle this connection. I close everything clear about it.
