I bought these jacks to connect to SFR my box to my CANALSAT HD decoder 5 stars. The result is perfect, up to my expectations (compatible with Canal sat, HD reception without problems, perfect picture); I can therefore benefit from Canalplus Canalsat on demand! The connection is fast and easy, no overheating, no cuts and a significant gain compared struggling recommended by canal-sat! so I would suggest that purchase; Bewan - Powerline S200 Maxx Duo - Powerline adapter with integrated plug and filter
