Find a reputable CB shop that does installs on the big trucks. I had mine done in Pa. Excellent job using two Firestiks and running the coax under the rig for a V type configuration. One Firestik straight up and one down as a counter poise on the rear ladder.
Where is your radio mounted? You appear pleased with your setup. Do you use the radio during travel?
I had considered the rear ladder but was concerned with signal losses with the long run of Coax to the CB radio, 4 watts or less, mounted on the front dash. Also, my interest in CB is forward Biased. What are the truckers ahead of me talking about?
Not much of a CB talker but like to know what road conditions are ahead. A 11m scanner probably would work in a pinch for my purpose.
Ideally i'd put an antenna or pair, with center mounted coils near the mirrors or close to that location. A 24" antenna with a center coil could be mounted relatively high and still be below the self imposed 13' 5" limit or lower. I'd like to keep them away from stay foliage.
Not sure the mirror housing will tolerate the wind load of an antenna mount, and using the cap, ideal, would need to get reinforcement before I'd be comfortable mounting antennas to the cap. Way too easy to crack that cap and damn expensive to fix.
The orientation should be vertical. Horizontal would not be effective for this application. Gone are the days of a metal roofs, too bad. Would make a great ground plane.
