I have used a mag mount previous however I'm tired of cables just laying in my jeep bed.  I wish to mount them though the body and such.  The local jeep uses cb and the mag mount used all the mount on the spare tire.  I want both antennas be easily removed in case I do notice any issues and so they will not interfere when I taking off the hard top and replacing it with a soft top.

I use a Larsen "thru the glass" dual bander on my truck and it works great.  That might be best if your Jeep is a rag top or has a fiberglass roof. I have seen them mounted on the front windshield up by the rear view mirror.  If you have a metal roof and don't mind punching a 3/4 inch hole, the NMO mount is the way to go. The various Larsen dual banders, 5/8 wave, or 1/4 wave whips screw on and off easily.  I have not had any experience with the trunk/door lip mounts, but they should be a good option.  Somewhere I remember seeing a motorized whip antenna mount that will allow you to lower the antenna from vertical to parallel with the roof.  An elegant, but I suspect expensive solution.

If they wind up closer, you may notice a slight change in the antenna pattern or a detuning of the antenna, neither of which should make them unusable.
