I put the mag mount on top of the car and ran it through the door. Doesn’t look like the coax is getting pinched. The weird thing is in some areas the antenna just won’t work. For example I just went to the grocery store with the antenna and I had no trunking signal with the antenna in the parking lot. I unscrewed the mag mount coax bnc from my scanner and put in the rubber duck and I was getting reception!! How is it that I was getting signal with my rubber duck and not my mag mount antenna!!?? What’s wrong here?
