I went out to the camper yesterday and pulled the antenna/cable outlet. Man oh man. I never expected to see so many connections for this system. TV, Radio and 12V. I can see now how it would interfere with the satellite signal. I thought about placing a splitter on the incomming "cable in" prior to the connection, but decided to just leave it alone. So, i got lucky and was able to run a new cable up though the bottom of the camper, straight up to the receptacle. Drilled a new hole and mounted a separate plate. Left the original in-tact. Now I have a dedicated satellite cable at the underside of the TT. I'm good. Thanks everyone for the help.
