Whatever you use, the antenna will have to be outside of the metal RV. Make
sure the long wire is insulated. A single strand, insulated conductor, run
around the perimeter of the RV is about as good as you can do. Even though
it is insulated, the antenna should be on short standoffs of some sort, of
an inch or 2 or 3, away from the metal roof. You should be able to run an
antenna of some 20 feet or more by stringing it around the perimeter. Don't
get carried away with length - 20 feet should be adequate.

You mihgt want to do a net search on "active antennas".

Some of the simple 1 JFET designs work pretty well.

If you Eamil my r2000swl@hot... account I will try to dig
one from Monitoring Times, scan it and send it to you.

It is nothing fancy, but with an 18" antenna it will work.
