Hi I wonder if somebody can give me some help please ? I have just bought a freesat dish to install myself and it has come with 15m of twin cable and a metre length of single cable. Now the Samsung tv I have has an inbuilt freesat tuner ( 55js8500 ) so I have no box to go into just straight from dish to TVs. Question do I connect both cables of the twin cable to the dish and both cables to the tv ? Or both cables to dish but only 1 cable to the TV ? Hope this makes sense.
