Cable company digital converter box
I have a 2012 Jayco Pinnacle 5th wheel. Normal cable tv was never a problem hooking up, and all tv's are new. I was issued a Comcast Cable digital conversion box at the campground office, but no matter what I tried I couldn't receive any channels. A Comcast tech came out and said his meter shows a decreased signal strength after the signal enters the 5th wheel from its normal cable hookup outside. He suggested that there is interference somewhere inside the rv causing the decreased signal to the tv. Now this guy is no rv expert, so I'm asking for help here, since I get normal cable channels at other campgrounds, and only encountered this problem with a cable box. Is there something I need to do different to make this work in an Rv? By the way hooking up the cable wire directly from the outside pole to the tv did produce cable channels, but I don't think I should have to do that.
