to avoid mounting a 2nd dish on the roof of the residence, I opted for the twin head in agreement with my upstairs neighbor! 2 outputs: each his own canalsat for 2 different decoders. Installation: 2mn, reception can max the decoder adjusting viewing bars, less waste and better reception than the head provided by canalsat. most: the golden pods supplied with 2! short for the moment that the right to recommend without hesitation!
