2/70 antenna placement

[338_MtRushmore]

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?

You could mag mount it in front of behind the 11 meter one

Ummmm, say what? Lol

Out the antenna in front of behind the other one

Ok, got it now. I guess I was just being a tool?

take a tool to know a tool..lol

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

Fender mount in front of the windsheild.

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.

 

[binrat]

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.

 

[338_MtRushmore]

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.
