I'm wanting to jump up to a 102" whip, but want to figure out a plan for mounting it on my crown vic first. The roof would make it a little too high, but the center of the trunk seems like a good second choice. With the antenna height and another 3' for the trunk height, 11.5' will clear everything the 12'3" box on my truck can. My question is- do I have to use a ball mount or are there other good options like a stud that would be strong enough? I would rather drill one hole rather than four for a ball. I read somewhere (don't remember where) that using an old saw blade on the underside would keep the car panel from flexing. Have you heard of that? I'm still learning and all comments and advice are welcome.
