"Yes, the tube is open all the way. Had to loosen the lower mirror bracket during the threading, but it went through very easy"
Terry, I m thinking of adding a FireStik no ground plane antenna on the passenger side mirror. I can't, tune the factory installed antenna to my CB and I heard that a no ground plane antenna will suffice and capture the proper SWR parameters. My question is, when you ran the coax through the passenger side mirror and through the door, where does it come out at and did you have to remove the inside door panel? I can see the factory wires and tube from the inside door jam but they appear to run to the engine compartment then back through the firewall. Thanks in advance and pics would be great if you can show it.
