I am running 3 radios in my mobile setup. A dual band 2 meter/440 MHz rig, a 220 MHz and a scanner radio in my new aluminum body F-150 pickup truck. I ran 3 separate antennas in my previous truck, 2 mounted on a BackRack cab protector that mounts in the forward stake holes on the rails of the bed and one on the hood. In order to park in my garage I needed to use the Diamond K9000 fold-over motors. These motors require “ground independent” antennas…. The K9000 is isolated from the truck body/chassis. The scanner doesn’t care if the scanner antenna is ground independent or not, but this is just background for my asking advice on using a triplexer or duplexer and reducing my “antenna farm” on the new truck. Ideally, a single tri-band antenna that is ground independent would work for all 3 radios but does anyone make a tri-band ground independent antenna? (I figure I could run the scanner off of the same antenna provided there is protection against feeding power through the triplexer.) in short, I’d like to provide as few antennas to my 3 radios as possible, using available triplexer/duplexer/ground independent antennas. Any ideas?
