Possible lack of good ground? How much of the antenna have you "snipped-off"?Got a brand new roof mount for the pick up aluminum of course drilled the hole mounted the mount and used the 62 in whip and the 66 inch whip still wont tune never had this problem before.. HELP!!!
Wow! You got me! I'm lost! Just wait a while and I'm sure one of the radio tech guys on this forum will step-in.Have not cut the antennas at all it worked fine on my last F 150... The mount is in the center of the roof..
Interesting information! You may have something there!My experience with their Aluminum, is they "anodize" that metal quite a bit to make the paint stick to it.
On top of that, the "Finish metal" is a simple cap - they don't weld Aluminum (at least very well) so you may have surface area - Read: Counterpoise issues on top of the "floating lack of surface area" and the Epoxy resins used to seal the finish metal to the base frame metal keeps RF stuck to the smaller surface
So you may have "''Olde' Lang Oxide" condition making the RF issue confined.
I would like to see a picture of that 3rd brake light mount. I had the cowl mount all installed on my aluminum ford but there is no easy way to run the coax. everything is sealed.Possible lack of good ground? How much of the antenna have you "snipped-off"?
I installed a Third Brake Light Antenna mount with a Laird NMO CB antenna on my '19 F350 and the VSWR is 1.1:1 to 1.2:1 on all 11 meter channels.

I do not have any photos of the mount on my truck, but if you Google; Bullet Proof Diesel Third Brake Light Antenna Mount, you will find several photos of the mount and a few installation photos. It is a darn expensive mount but it is working-out great for me.I would like to see a picture of that 3rd brake light mount.

I have and tested three reputable NMO CB antennas. After trimming, all three antennas work great with outstanding VSWR readings..I would like to see a picture of that 3rd brake light mount.
