I don't run the lower windshield bracket on my car so I put the antenna right up against the windshield frame right in the center. Ran the wire under the gasket and dropped it down through the hole where the windshield goes through the body. seems to work just fine. I suppose you could put it off to one side or right in the corner.
I also thought about moving it down to the mouth opening above the
oil cooler opening. Hell they give you a long enough lead to wrap it around the car twice...lol. That's a bit of a stretch but you get my drift.
