Dash Install-
The following is a custom install of a Uniden 40 channel CB where
my ashtray used to be... I don't smoke so it seemed to be a logical
place to put it and the Uniden 520xl (also the 510xl) fits that area like a glove. Follow along
on my install...
Pre-Install
Materials
Needed: CB, 18' quality Coax, and antenna and mount.
Other
Recommended Materials: Silicone sealer, zip ties, soldering iron,
electrical tape, Wire split loom.
- I
started my install by reading... yup that's right I researched about
antennas, radios and how CB radio waves act. I also asked a lot of
questions from a local CB shop. One good source of information was Firestik's
website. This manufacturer of CB antennas has an excellent FAQ that
covers a lot of questions for the beginner.
- Next I
selected my mounting point for the antenna the CB location in my
truck and also decided how I was going to run the Coax to the
antenna. Then went out to buy all the goodies.... I had a buddy of
mine machine a suitable mount for where I wanted to mount it at the
time (Cost = 1 case of beer)
Used
for this installation:
3'
Firestik- this antenna is a ""top-loaded" antenna
meaning there are more wire coils towards the top of the antenna.
Uniden
520xl- a very compact but quality CB radio. Features a PA./speaker
output and switch a jump switch to channel 9 and a gain knob.
Antenna
mount- I originally had a antenna mount machined by a friend out of
aluminum that clamped to the factory bed tie-down. After getting a
diamond plate tool-box, I then got a flat Firestik Stainless steal mount
and bolted it to the bottom of the box.
Installation
(tips
section below install)
|
Tear
apart your
dash so you can gain access to a place to run your wiring and mount
your CB.
- Remove
all of the control knobs from the Heat and A/C controls and also the
A/C button.
- Remove the 2 screws from underneath the in-dash cup
holder.
- Then gently remove the center console plastic trim.
|
|
- Starting from the bench seat storage
area.
- Run enough coax out the rear grommet of the
vehicle to your antenna mount.
- Run cable front to the CB. (more to follow)
- This enables you to loop the excess in the
storage area out of site.
|
 |
- After running Coax out the rear grommet I
ran it up the back of the bed, over the bed rail and to my
CB mount. Leaving a loop of Coax to drip off water.
- Zip tie your Coax in place to keep it from
vibrating loose.
- Then seal the grommet you had to slice to
get the coax out with some Silicone sealer.
- Remove your plastic door sills, kick
panels, and also the lower plastic trim that runs under your
steering column.
- Run Coax out the drain hole in the corner
of the bench seat storage area, under the carpet and down
the wire channel- underneath the carpet.
- Through the kick panel area and underneath
your dash to where your CB is installed.
- After making sure I had enough Coax to the
CB I then zip-tied it in place.

 |
- I chose to mount my CB where my ashtray
used to be. I removed all of the ashtray guts, then using a
Dremel tool cut the back out of the ashtray area.
- Slid the CB in place and secured it with a
generic radio strap to hold it in place.
- This made for a compact, clean and secure
location for my CB.
- I wired my CB directly to the cigarette
lighter beside it only b/c there was not much on that fuse.
- It is recommended by many professionals
that your CB's "hot" wire get run back the
battery. Then well grounded to the firewall.
- Test the install, fire up the CB to make
sure it comes on. But do not broadcast! this
could damage your radio unless your antenna is tuned.
- Tune the antenna to the lowest SWR's-
meters are commercially available, I chose for this install
to have a Pro tune it. Cost was around $5.00 and it took him
all of 10 minutes to do it.
|
 |
- After making sure the CB works, tuning the
antenna, and doing some general clean-up of the wires. It's
time to put everything back together.
|
Some tips I used:
- All electrical
connections were hard wired for least electrical resistance.
- All the wiring and coax used on
this install, was covered in wire-loom for safety.
- Antenna was tuned by a
professional... remember CB damage can occur if care is not taken to
tune the antenna for lowest SWR's possible.
