One thing that every ham does when he gets a new vehicle is try to decide where to put the radios and antennas.  I have to figure out where I am going to put antennas on my 2006 Wrangler Unlimited Rubicon.  There are not many, if any, flat places to mount an antenna.  I have searched “Jeep Wrangler” on the EHam forum site and found that I am not the first to face this issue. There are those who recommend drilling a hole in the cowl between the windshield and the hood, and those who have looked for other places.  As in any vehicle, the compromises are asthetics, ground plane, overall height, durability and all the other factors that influence how well signals get into and out of the antenna.  One option is a ball mount on the side of the Jeep behind the door.  Downsides of this include the hole in the sheet metal, the risk of scraping it off with a branch off road and the fact that it will not have the best ground plane.  My Jeep has a Body Armor brand spare tire carrier with a flange on it for an antenna.  However, I am concerned about how well grounded this is and how high the antenna will be if it is mounted here.  Others have mentioned the use of brackets that bolt in the same holes as the tail lights and provide a flat mounting surface for antennas.  I would think these would work for V/UHF antennas, but am concerned a large screwdriver would not have sufficient support on one of these.  When crawling under the Jeep before I bought it, I noticed the posiblity of putting a bracket on the frame wehre the rear bumper bolts on and coming out the side to the rear corner of the Jeep.  This would offer grounding to the frame, a strong mount and even though it would be on the side, it would not stick out as far as the tires or wheel wells.  Being low, it would avoid getting hit on parking garages, but it would also run the risk of being underwater when fording.  I don’t think most screwdrivers are designed to go underwater.  I am also worried that mud coming off the rear tire would collect on the base of the Screwdriver.  Maybe a sealed High Q antenna is the way to go here?  My goal is to get into a 6 1/2 foot clearance garage without damaging my antennas (assuming the whip on the HF antenna is pulled over).  The top of the jeep is almost this tall, so having the top of a whip much more than this height will cause problems.  I use the Larson on my truck and I think it is 39 inches.  Maybe that is the solution for mounting on the tire carrier or one of the tail light brackets.  That brings up the question of where to mount the radios.  I will write more on this later, but the best options at this point seem to be an overhead rack between the windshield and roll bar or on the face of an aftermarket gauge mount that would go on top of the center of the dashboard.
