GOM...IT FAILED to stand the test. Keep up!
It's a JEEP, look at one in the parking lot some time.
I'm from the UK, not many people are stupid enough to have big 4x4 petrol guzzling behemoths here.
I've looked at pictures of a jeep. I can find a thousand places to mount an antenna but then again, I'd not be using a SGC (which I do own).
The rason I thought about Heliax was that it might provide the needed insulation, if I just used the center conductor, and not the braided shield.
Heliax is coax. The SGC manual specifically says not to use coax. The fact you're not connecting the braided shield is irrelevant.
