CB Antenna Mirror Mount?

[lasgambler]

Hello, I have been traveling alot lately and have decided to install a CB. I have a 4 foot mirror mount CB antenna and have put it on the passenger mirror. I now am having a hard time deciding on how to route the coax.

I was also wondering if the mirror on the Superduty is a good enough ground?

I searched this forum and could not find any info. Thanks for any info. Terry

How exactly did you mount it to the mirror? Any pics?

It is a mirror mount antenna. Has 2 clamps with seratted teeth that clamps around the top mirror arm.

If it were mine, I would run a wire from one of the bolts on the mount to a "good" ground just to be safe. I would hate to see a C.B. radio fried due to a bad grounded antenna.

What "ground wire" are we talking about here? My dual antennas are regular totally encased coax cable all the way from the antenna to the radio. Nothing exterior to connect?

There is NOT a ground wire there......make one out of 14 gague (or there about) wire... put an eyelet on each end....one end...bolt it to one of the mounting bolts for the antenna....the other end...bolt it to a good ground(i.e. the frame or door hinge bolt)

Wow. And that protects the CB? I never knew that. Thanks for teaching me something new to protect my equipment!

Yeah, thanks for the info on the ground. my antennas are on my mirrors but i dont even have a CB in yet. as far as running the wires I just ran the one from the passenger side under the hood under that plastic vent piece and then I ran the wire into the cab just right under the whether stripping

If it is not grounded good, the SWR's will be bad high...high SWR's will, over time,burn the finals in the radio.Depending on the radio, this could be VERY costly to fix.


Hope this helps.When you get it all installed,You can go by a radio shop and they can check the SWR's and make any necessary adjustments.This usually cost $20.00 or less

Thanks for the replies. Right or Wrong, I just went out and ran the coax under the black cowling, down behind the fender in the door jam and then though the same hole as the am/fm coax. I had to pull the plastic entry at bottom of door opening and the triangular piece under dash on sidewall to access the hole.

I had to cut the factory PL-259 off the cb coax to get it though the hole.

I would still be interested to see how the professionals do it, as there probably is a better and cleaner way.

Thanks, Terry
