With the mount secured to the fender, it was time to attach the coax to the mount. Again, the kit includes stainless steel hardware here too to help fight off corrosion from the elements and salty winter roads.
The FireRing on the end of the coax has a slight shoulder on one side of the
white insulating material. This matches the shoulder on the white
insulating washer (white ring). When properly assembled, these two
shoulders face each other and meet half way through the mounting bracket.
You can see the small shoulder outlined on the antenna mounting
stud where it passes through the FireRing connector. This shoulder keeps
the bolt from touching the antenna mount and shorting the RF signal to ground.
The white insulated washer sitting on the antenna mount has the same small
shoulder on it. Be sure to install it correctly.
The FireRing is positioned on the bottom of the mount. The
insulated shoulder washer (with the shoulder facing down) is slipped over the
antenna mounting stud.
After the insulated shoulder washer is in place, the flat washer
is placed over the stud followed by the lock washer. To hold everything in
place (and provide a place to attach the antenna), the coupling nut is screwed
onto the antenna stud. In the above photo, I've not yet tightened the nut
as I wanted to better show the correct placement of the parts.
To finish up the antenna mount, I routed the coax through a nice
little notch in the body right at the corner of the hood. There is a large
oval shaped rubber grommet located above the gas pedal. I cut a small X in
the rubber and then pushed the coax cable through the hole and into the cab of
the TJ. Over the years, I've used the rubber grommet for a lot of cables
and it works well to get a wire into or out of the cab.
