Moved my motor home, tried to setup DirecTV, got a good 85 to 96 signal for appx 30 seconds then it drops to 0. It does the same thing regardless if I use my rooftop KVH-sf dome or the ground tripod. Tech told me maybe static in line, removed the line and grounded, same thing, changed the cable, same thing? reset the recvr, unplugged the recvr, removed the card, all the stuff the Direct techs tell you to do. what does it sound like to you guys?
