I am having to buy a short CB antenna for 11 meters for my vehicle. It is a center roof puck mount. It can be no taller than 3 feet +- an inch. I hate the idea but I need something for this purpose at times when driving. Around 500 watts power handling minimum. The antennas I have looked at so far were the Firestik IIFS 3ft, Skipshooter 3ft, and the Skipshooter Double barrel Base loaded. Any information on any short antennas that are better or the best to use for the most range at 3ft max for CB channels?
