Jeep Tailgate CB Antenna Mount
For Use with a Swing Out Tire Carrier
If you have a bumper/swing
out tire carrier like the one made by LoD,
here is a quick, cheap and easy way to make your own CB antenna mount
using the bolts left behind from your old tailgate tire carrier.
If you do not have a swing out tire carrier, check out my original
CB antenna mount write-up
which is designed to be used with a factory tire carrier.
What You Will Need
x 1" Angle Steel
• Socket - 1/2"
• Wrench - 1/2", 5/8", 3/4"
• Jig Saw w/Metal Cutting Blade
• Bench Vice
• Safety Goggles
• Drill Press or Hand Drill
• Cobalt Drill Bits - 3/8", 5/16"
• Drilling Oil
• Center Punch
• Grinding Bit
• Metal Cutting Bit
• Metal File
• Rubbing Alcohol
• Primer & Paint
Take your angle steel, measure a 5" length of it and then mark
it with a Sharpe marker.
2. Place your angle
steel in a bench vice and slowly cut off the 5" length using
a jig-saw with a metal cutting blade. The best way to do this is to
cut through one half and then flipping it over to finish it off. That
way, you are always cutting on the flat side (see pic to the left).
3. Using a metal file
or Dremel with a grinding bit, clean off any rough edged or burrs
left behind from the cutting.
4. Lay your bracket flat on one side and mark off
two drilling points 4" apart, center to center using a center
5. Flip the bracket flat on the opposite side and
mark off one drilling point in the center using center punch.
6. Position your bracket on your drill press and
clamp it down (if you only have a hand drill, clamp the bracket to
a wooden board). Now, put a little oil on and then slowly drill the
two mounting holes one at a time using a 3/8" drill bit. Make
sure to re-clamp your bracket down each time you move it. Then, flip
the bracket, position it, clamp it down and then drill out the single
center antenna mounting hole using a 5/16" drill bit. Clean up
the rough edges and burrs using a Dremel with a grinding bit.
7. Now, go to the back of your Jeep and remove two
of the upper bolts that used to secure your factory tire carrier to
the tailgate. You will need a 1/2" socket or wrench to do this.
8. Do a test fit of your new bracket onto your tailgate
to make sure the holes you drilled are accurate. If the bolts do not
fit correctly, place your bracket in a bench vice and widen them up
a bit using a Dremel with a grinding bit or metal cutting bit. Repeat
process until your bracket can be mounted with ease.
9. Clean your bracket thoroughly using rubbing alcohol
to remove any oils left from drilling.
10. Prime and paint your bracket. I used Rustoleum
Auto Primer and Industrial Hard Hat Gloss Black. Allow 24hr. drying
time before mounting to your Jeep.
11. Bolt up your new bracket to your tailgate using
the factory bolts as shown in the pic to the left. You can bolt it
up with the antenna mounting surface up or down. I chose to bolt mine
up in the down position only because it gave me just enough clearance
to get into the garage with the antenna on. I also mounted my bracket
using the driverside bolt so that the antenna would clear the hard
top glass. If you do not have a hard top.
you're just going to bring you coax cable into you Jeep through the
tailgate or through the window, you are pretty much done here. However,
if you want to route it through the tailgate like I did, then now
is the time to bust out your trusty Dremel. From here, you'll need
to remove the plastic cover, undo the wiring for the 3rd brake light
and pull it out of the tailgate door.
13. Using a Dremel and a metal grinding bit, I
widened the existing hole large enough to squeeze a the connecting
head of the coax cable. Touch up the rough edges with some touch
up paint to prevent rust.
14. From the outside of the tailgate, fish the
coax cable through one of your new rubber grommets, pull the cable
inside of your Jeep through the tailgate hole and then cap both
sides with the new grommets.
15. Using my Dremel again, I cut a notch out on
the plastic cover for the cable to come out (This will also hold
your cable in place) and then routed the cable along side of my
tub behind the carpeting.
16. Put everything back together and you are done.
That's it, your done! This project should cost no more than $5 in
materials. Please let me know if you have any questions.
