Here is where you should mount your CB and HAM antennas on your Jeep

Yea I was thinking about their mount, just not sure if it would help with the ground situation..
For the electrical ground it would just make it worse (you have to scrape the paint off of the ARR mount and then it'll rust in a few weeks).
For the RF ground it won't make any difference (elevating the antenna another foot or so will not change the electrical properties of the antenna or it's surroundings).

*** MORE TECHNICAL UPDATE *** 11-12-14
Recently I cracked my intake manifold changing a censor. I had my mechanic add some headers and new spark plugs at the same time he replaced the manifold. Needless to say by doing so we disturbed the electrical system of the Jeep thus causing RF (Radio Frequency Radiation) leakage. It sounded like bacon frying on my VHF and UHF analog ham channels all across the spectrum, both receiving and transmitting.
To solve this problem I ended up swapping my dual band VHF/UHF antenna from the Cowl to the back and put my 800 MHz antenna on the Cowl. This got the antenna enough away to solve this problem.
But a new problem was also discovered. My 800 is a commercial digital radio and although the digital signal did not pick up the “bacon frying noise” it made the radio less sensitive.
To solve this problem I tried to put a brand new coax with new antenna and connector, SWR checked great. But that did not work so I ended up relocating my 800 antenna to the rear light bar bulkhead mount as seen in the above pictures. Once there my receive signal strength came back.

They make resistor plugs and wires and with the ECMs and CAN bus you might think about using them. It will drastically reduce the EMI created while spark events occur and you should be able to put your antennas back where they worked before

I know i read do not mount between spare tire and tailgate but wondered if this mount would be ok considering its a lot higher up and 3/4 of the antenna would be out between the two.

Did they change the plug wires too?

Well it looks like your going to mount an antenna on the tip of a triangle? Unless your making a costume flat mounting surface that will be clamped or welded there I would not mess with it. Go to the cowl or even the bumper at the edge would be better. I did one of those between tailgate and spare tire mounts for a guy with a Toyota Land Cruiser. We tested the SWR with a short fire 3' stick and a long about 6' the longer one has almost now SWR and the short one required lots of adjustment. He chose to mount it there because he already had a HAM antenna on the Cowl.
The antenna itself would be only be between the back of the Jeep and rear tire for 7inches before it clears the tire. Then roughly 17inches before it clears the hard top leaving 19inches of a 3ft antenna completely open centered above the rear of the Jeep. With the antenna being like this would i have fairly good distance with it on the trail? Obviously nothing crazy but good enough?

Has anyone considered using a windshield light mount and using it for an antenna mount?
I'm looking at getting a handheld CB with an external antenna option and I'm thinking about doing this...
Thoughts?
