My pickup truck is used to haul a 5th wheel trailer, which means I can't put an antenna on the back bumper, or on the sides of the bed. The only places that seem to make sense are the front bumper, or the front portion of the bed behind the cab window. In either case I'm concerned about interference from nearby metal. I already have a dual band antenna roof mounted. Another thing is, sadly, I live in an area where meth-heads steal anything that looks like it can fetch ten bucks. So a fancy screwdriver antenna is not a good idea. On the plus side I have no vertical constraints as I never park indoors or have clearance issues. Figure running 100 watts out of the HF rig. What might be my best approach and antenna selection?
