RV or trailers provide an excellent base to install effective low cost antennas,
and both configurations, end fed or loop antennas can be used.
An End fed antenna could be very effectively used if a metal cabin structure is
available. Loop antennas have the advantage of not requiring a ground sys-
tem, but are highly directive. Mounting the antenna is relatively simple and
can be mounted on short (18 inches 1/2 inch diameter) plastic plumbing pipes.
In the end fed antenna, it is recommended that the antenna be as long as pos-
sible in an "L" shape configuration, as illustrated in the following diagram.
