Thanks for the write up. I referenced it yesterday while installing my new Cobra 150GTL and Firestik FS3.
My $0.02:
I ran the coax from the antenna mount, down alongside the tail light and cut a small hole on the bottom side of the rubber wire housing feeding the tailgate. I was then able to remove the driver side trim to reach in and pull the cable through. Running it along the kick panel was surprisingly easy.
I spent most of my time figuring out where to mount the big radio. I didn't want to put it up on the roof like i'd seen some do, and i wanted to be able to see the unit while driving which ruled out under the seat etc. I tried every bracket position available and finally ended up drilling a couple of new holes in the bracket to mount it where it is. I had to get it perfect so it doesn't hit your leg while driving, clears the tilt lever, clears the door handle, and is visible. I also ran the mike cable into the trim and up the pillar where there is about 2 feet (uncoiled) of cable available and it provides a nice clean install.
SWR was great...1.2 or less on 19. Reception is horrible! I think the 3 foot antenna is the problem. I'm stopping by a local CB shop today to try a longer or different antenna.
