If you're offended by the thought of watching TV while camping...you might want to skip this post...
I've never had much luck getting a (decent) signal while camping.
Seems most campgrounds where I go are in the river bottoms, or otherwise blocked from receiving the signal.
We've tried various antenna setups, but have not found anything very effective.
This time, we opted for a DVD player, works great!
However, I'd sure like to be able to pick up a local station.
While building the latest trailer, a brilliant (I think) idea came to me

Since I was building the roof in layers, I installed a large, and a small loop between the two sheets of plywood.
The leads come inside, and are hooked to a coax tee.
The tee also accepts a coax cable that terminates outside the trailer, so that an exterior antenna, or cable TV (when available) can be easily attached without running cords through the window, etc.
I found a really neat little cap that protects the end of the cable connection at Lowes.
Don't know how well this "internal" antenna will work, but it picks up two stations inside my garage, if I'm really lucky, It will prove to be a good idea...if not, it'll make a great lightning rod!
This picture shows the exterior mounted cable hookup, with the protective cap.
