I scooped a nice HF ham antenna as part of a package. It's fairly heavy due to the construction and ideally should be mounted high and centered on the vehicle.
The antenna is this: The tarheel II, it's about 16" tall and 2 lbs. or so. Here's a picture. I'm not into drilling visible holes in my roof or using magnetic mounts for the antenna. I plan to fashion a simple L shaped bracket about 6-8" wide and about 4" tall and the leg of the L will be about 1.5". I'll drill the 1" hole to pass the antenna base through and then lock it down.
post suspended till i can get some pics to explain things clearly. I'll get back to this.
