put cb antenna in a while back, just getting around to posting pics...
i did the same tail light area mount as several other people, but with a couple variations to clean it up a bit. for the mount i went with the firestik SS-134 which is a little narrower than i've seen others using... we'll see how it holds up: http://www.firestik.com/Catalog/SS-13.htm
then for the cable and stud, i used the firstik K4-8R18 firering style connector so that it wouldn't hang down into the light as much: http://www.firestik.com/Catalog/k4-8r18.htm
here's a pic of where i routed the wire into the cabin. from there, i then ran along the door jam, then under the carpet beneath the passenger seat (had to remove the seat to manage), then up into the center console and to the CB unit:
here is a shot from outside with the tail light removed. i used some industrial aluminum tape to secure the cable, and 3 screws along with JB Weld to secure the mount. the yellow thing in the picture is unrelated, just a load-equalizing resistor for my LED blinkers:
another difference, i used a dremel to notch out the tail light to have room for the mount and cable, so that it would sit in the exact same location as stock instead of with a slight down-angle:
here you can see the final result:
for an antenna, i'm using a 3' FireFly (FL3-B) that i already had, i'll probably switch to 4ft when i get around to buying one. the FireFly series is just a little lighter than the FireStik series and works fine unless you are running a linear amp with high wattage.
[i need to update this later with a pic of the antenna actually installed]
i also went ahead and ran a mount and cable for a HAM radio even though i don't yet have one (figured as long as everything was torn apart!). i did the exact same wire routing and mounting bar, but used a Diamond Antenna C213 cable. i'll probably go with the Diamond NR770HB antenna once i get a HAM rig and license:
one final shot from the back showing both mounts:
