I've got one 7ft firestik antenna (highway driving) and a three footer (tuned for best SWR on CH 10 so, my swr is still good on CH 4 up to 19) and use the firestik quick disconnect to switch between antennas on the fly plus, the quick disconnect makes for much easier tuning. I'm tempted to try out a 102 inch whip antenna as they are allegedly the best for CB's but, just haven't got around to it yet.I ran the coax up to the front and tuned the CB. I regretted getting the 48" firestick antenna. Mainly because of the torn meniscus in my knee. Crawling up the back of the FJ to reach up and play with a knob, then crawling back down to see what the meter was telling me, then crawling back up the back and repeat until the hurting outweighed the desire to adjust the knob by 1/8th turns.
CB is in and working and on a CH4x4 switch. Now I just have to figure out where I want the connection to stick out.
