Hello. I have a decoder from the digital Polsat HD 5500s and satellite dish (also from the digital polsat) which I have mounted on the chimney and I do not have any obstacles, I connected the wires and signal that I managed to set: signal power 80-83%, signal quality: max 50% (sometimes shows below), but after searching for channels I still do not receive anything but I write that there is no signal when I want to install channels, I get an error and I do not want to install, please help, thanks in advance.
