Hello, the problem is that I have a regular antenna on the roof that receives channel 8, i.e. mux8, where there are some tv wp channels, new, metro and 4 test channels, and my point is to receive at least the basic tv channels, i.e. tvp1, tvp2, Polsat, from what I read on the net, you need to receive mux3, before all the confusion with digitization everything was ok, on the old antenna, the so-called with a plate, where it was powered from the power supply at the TV. Currently, I have replaced the coaxial cable with a new one, which was connected to the old analog aluminum antenna lying on the roof, what do you need to set up or do to receive mux3 or at least tvp1, 2, Polsat?
