It is very hard to beat one of these WINEGARD BATWING antennas. This has a booster amp built-in that gets activated when you push in the button on the ANTENNA WALL PANEL...
Some of the newer trailers are coming out now with inferior round and low profile omni-directional antennas...
If you have this Batwing crankup antenna on your trailer it is one of best ones you can find... NOTE the added dipoles


Don't forget this is just like your HDTV setup in the house as you have to select ANTENNA and then scan in the digital stations from the HDTV menu setup... When you are hooked up to CABLE TV at the camp grounds yo have to select CABLE from the HDTV menu and do the scan again...
