SenorMoofer is thinking along the same lines I am. If you have tall trees close to the trailer, consider hoisting the wire version of the Off-Center Dipole up into a tree. The difficult thing will be positioning the 75 ohm coax feed line so that it runs away perpendicular at a 90 degree angle from the vertical portion of the antenna for at least 3 to 6 feet before it goes downward. Use 75 ohm TV coax.... not only because it is a proper match with the TV transformer balun, but also because it is low loss, but because it is lightweight enough to pull up into the tree. Pull the coax cable in through a window.... or if you have a passthru port made to bring in a TV antenna.
