Hi fellow RVers. I'm fixin to install HF in the Travel Trailer for (obviously) fixed operation. The Tarheel seems to be as good a compromise as any, but I wanted to run my understanding across the hive; Installing the tilt-over base on the roof of the camper, so that while under way (being towed) the unit lays on the roof with proper supports, the base would be towards the front, and the coil/whip fold down towards the tail. The obvious question is regarding the RF Ground. The roof of the camper is roughly 9 feet above the twin I-beam chassis of the trailer. Running a ground strap from the chassis frame to the tilt-over base seems to be little value. So, if this were a VHF install, I'd proceed to construct some form of metal ground plane skin that would be adhered to the rubber roof membrane. VHF is easy at least conceptually. But I can't imagine an 8 foot wide by 8 foot long section of "groundplane roof" would make any difference at all for HF. So, for all the photos we see of RV's with a screwdriver on the roof - how are they RF Grounded? You're over 11 feet over the Earth ground, so little if any ground capacitance can occur. Tarheel instructions instruct the installer to make sure Vehicle Ground is within 12 inches of the base. Thats impossible to achieve on a fiberglass sided stick built RV camper.
