Well, I got 12" Wilson antenna with FME connector and replaced 6" Anycall antenna. It sticks out much more out of roof rack now. On a recent trip to Uvas Canyon my wife was yapping with her mother for a few miles more. She did appreciate extended range so I guess I got small brownie points.Did you go with the Wilson unit or ?
I’ve been considering a booster too.
I think I will try to epoxy some neodymium magnets or clamp screw some steel plate to the aluminum cross bars so I could mount the antenna higher.
