We bought a 2008 Big Horn 3055RL in May of 2007, but have never tried to use the roof antenna for TV reception always using the cable connection. Currently sitting in the Southwest Orlando KOA with extremely poor cable reception on the lower VHF channels 2 thru 6. After several attempts by the KOA staff to resolve the problem, it remains. I was told that the local stations can be received quite well via the roof antenna. After consulting the Owners Manual for both the Big Horn and the Olevia HDTV I found no guidance regarding use of the antenna. There are only two BNC connectors behind the TV one for cable and one for satellite. I have no satellite antenna. After raising the roof antenna, I got no signal. Anyone know how to solve this problem? Also, I find nothing indicating that there is an amplifier for that antenna unless it is hidden in the structure of the Big Horn. There is no mention of it in the Owners Manual.
