Don't waste your time with ground radials on a car. Focus on the rf grounds.Hey Rabbiporkchop....nuthin for nuthin, but in that vein of thought, if you were to use a beedlove puck mount, and drill&tap it for lets say 8 radials about 18" each and then mount a sirio 5000 would that give a decent/better ground plane? Just a thought, probably been tried.
Thanks for the link, will be useful.@Limeybastard:
I would recommend going to the ARRL website, and ordering a couple of books on antenna basics.

Antenna theory is far more complex than I had ever thought, unless you happen to be a mathematical wizard. But, it's useful to get into.
Also, invest in good coax. Using cheap coax could be likened to plumbing your house with soaker hoses.
Running a +70w radio with a mag mount seems like it should do well enough all on its own - IMO . . .
Fek, thought didn't think my antenna was that bad. But what do i know, not much hence here.at your mercy lol.
I couldn't give a toss about drilling a hole in the roof, but by how much would that improve performance compared to similar mag mount install? Dont need to be exact, a rough figure would suffice. 10% better, 20...%? I was under the impression that a good mag mount was good. Failing that a 102" ball mounted whip as high as possible , for practical reasons perhaps back of bed near cab as high as possible to reduce reflection.
Surely then adding an amp would allow me to "touch" further after mastering the antenna projects ?
I hear folks from alabama, Oklahoma, trinidad and Tobago , Louisiana, Massachusetts but can't talk to any of the closer ones to me. Im in central Florida Hernando county.
