If you happened to read the installation write-ups I did for the
Uniden off-road CB kits, then you may have noticed the two different
antenna mounts that were used in those kits. Those
CB off-road kits are
assembled and sold by
Channel Radios and make for one stop shopping for CB radio
installations. Bob, the owner of the TJ with the Cobra 75 radio, decided
he wanted a different antenna mount. RCR now carries the
antenna mount and it was decided to give this mounting bracket a try. It
can be ordered as just the bracket itself or as a
complete antenna mounting kit, which
includes a coax cable, antenna mounting stud, and the Teraflex bracket. So
the mounting kit was obtained and we started the installation.
The Teraflex mount comes with a one page Teraflex instruction
sheet that seems to cover most everything required. The cable and mounting
stud shown above, included by RCR, completes the kit.
This mounting bracket is designed to utilize the holes for the
passenger side (driver's side if you wheel down under) tail light assembly.
With a Phillips screwdriver in hand, Bob and I started the install. The
first step was to remove the tail light lens from the assembly.
With the lens out of the way, the three mounting screws were next to come
out. An extension for the ratchet was needed to reach the recessed screws.
Once the three scews were removed, the tail light assembly can
be removed from its mounting position. This one was a little "stuck" in
place by some goop that was applied to the back of the assembly. You can
see a bit of it around the triangular outline on the TJ's body.
The mounting bracket was nicely powder coated. One thing that will certainly make antenna tuning a nightmare is a poor RF ground, which powder coating promotes. The antenna mounting stud needs to make a good RF ground with the body of the vehicle and in order to do this, we need to have metal on metal contact. The stud must have a clean connection with the mounting bracket and the bracket must have a good connection with the body.
To ensure good connection were available, a small circular (rat tail) file was used to remove the powder coating from the inner surface of the mounting holes on the bracket. About a minutes worth of time spent cleaning out the holes goes a long way in ensuring the antenna tuning process goes as smoothly as it can. You could also do this with a small sanding drum on a rotary tool, such as a Dremel. I found the round file worked very well and I was done in almost no time.
