I have a hard mount for 11 meters on my roof, and curious what my options are for a 2/70 antenna mount. I have 26" from the coil to the back and sides of the cab, and 31" to the windshield. Is that too tight to squeeze in a larsen 150 on the roof, or do I need to mount it behind the cab on the welding machine? I'm planning on an icom 2730a. Any thoughts?

Of course. I will probably just grab a hole saw and drill every 2 degrees around the roof and check each ones field strength. Seems reasonable?

Since you're obviously not afraid to drill holes...I would do a permanent nmo mount 8-12 inches in front or behind your puck mount.

I guess I will pop a hole 9" behind the existing puck and see what happens.

It should work fine with little interaction between the antennas

Is fender mounting a good option for vhf/uhf? I'd never mount an hf antenna there, so the thought never even crossed my mind.

I've run a few, there are not as good as top dead center but are a good alternative.

Are you planning on running simplex or repeater? For repeater the fender would be fine.

I would guess 90% simplex, but 90% of that would be within 1/4 mile. It would be nice to get some distance when truck drivers crank the squelch on their cb. Maybe I should stay with roof mount.
