I bought a Galaxy SSB off of eBay and it was modded for me. I am using Wilson 5000 antennas, (twin setup) with mounts I bought off eBay too. I bought a powder-coated overhead rack and mounted the radio to that. The specialized CB antenna mounts I bought also came off eBay.
The antennas are mounted to the exterior area just forward of the A-Pillar. Originally, I had mounted to the hood area, but because of the weight of the antennas, I needed a stronger support mount.
With the dual setups, I have an SWR of 1:1, and I have no difficulties talking to truckers at 15 miles or so. The radio itself has an output of around 25 watts AM and 55 watts SSB,
