Cobra 75 installed earlier this week. I decided to do a "temporary" install to see if I like it and how it works.
Antenna mounted to an existing 1/2" threaded hole in the Teraflex tire carrier. Had the welder make me a simple aluminum L-bracket. SWR meter reads amazingly low for this crappy location; 1.2 or something like that. The one good thing about the TF carrier is its aluminum and well grounded through the hinge. I have no external ground wire!
Then I brought the coax in through the carpet, down to the back seats and over to underneath the front driver seat. I just set the little connector box for the Cobra under the seat for now. The handset plugs in there and will sit just to the left of the transfer case shifter. For now I just toss the handset under the seat, but if this becomes permanent I will mount the clip holder along the vertical face of the cowling where the handset is in this pic. It is well out of the way of my long legs:
The remote speaker is up next to my head on the left near the B pillar. Wires run down the pillar, under the rear full-length mat. I just used a few wire ties to hold the speaker for now.
It would be simple to remove the whole thing if it doesn't work out. We'll see how it goes.
