Yea, not drilling a company vehicle, especially one we are getting rid of in less than a year. Also, the sunroof makes the area to drill microscopic. (I'm using Flickr for photos, if they are not working, let me know please) Anyways, I got Tram 1267 mount (5.5" base, my screw up, didn't read the size) and a Tram 1126B quarter wave antenna. My problem generated by my screw up, the corrugation pattern on the roof sheet metal makes it so I have to set the mount forward of the corrugations. See the photo: GMRS Antenna by tweiss3, on Flickr Question #1) Am I correct in the fact that its too close to the sun roof, so it won't transmit in the forward direction well? Secondly, I want to set it to the back so I can tuck the wire nicely, like I have my CB antenna. Will it cause any issues if I mirror it from the CB along the back? Won't overload the car radio? S the photo below. Roof Antennas by tweiss3, on Flickr This is my GMSR-V1 for now, but if my bid goes well, it will be a 45W mobile mounted in the back. Question #2) If that were to happen, will it cause problems if I loop the excess cable on itself to tuck it away? Thirdly, I bought a NanoVNA due to its wide availability of use. I tested the Tram antenna as installed above in the car. I'm pretty impressed. SWR 1.3 is pretty good (-16db return loss).

Is there anything else I should test on that antenna? Is there a way to verify my little 2W radio is getting out and not loosing too much through the cable, or is that what the SWR/Return Loss is identifying. Thanks for all the help so far. This place is a mountain of information and help.
