Of course the best antenna I ever used was one of the LOWES $90 long yagi's but it destroyed itself from me having to fold it up when in transport. Did last a year however. It stuck out a good four feet or so over both ends of my POPUP trailer hehe.. Sometime I couldn't turn it for hitting a tree...
This is a photo shot of my present BATWING antenna setup with my OFF-ROAD POPUP trailer - Does very well camping off the power grid...

Here at the house I have been experimenting with one of these DB8 antenna from SOLID SIGNAL.com. It was recently on sale for $49 and I picked up one. This is one of those Eight BOW TIE two flat panel antenna that picks up our HDTV OTA Broadcast signal from Washington DC some 50-60 miles North of us. This should work out great when camping off the power grid and I will have it up in the air about 12-feet with my PVC antenna mount. I added a RCA TVPREAMP1R that will operate from the RG6 TV feed line supping 9VDC from an inline power feed down in the trailer.
My HDTV in my trailer is a 22-inch VIZIO from WALMART...
Looks like this google image...


Will let you guys know how it works out off the power grid soon... Initial test here on the ground comparing with a BATWING usig the same PVC pole looks very promising... I am picking up 36 or so full screen high Def BROADCAST SYSTEM TV signals from the Washington DC area.
