The mounting screws could be touching the conductor of the antenna screw to the bracket attached to the vehicle. Make sure the nylon washer is seated properly within the hole of the bracket, and isolated within to top, bottom, and side.

What nylon washer are you talking about? Is there supposed to be one between something?


With your antenna mount, it has multiple pieces, from top to bottom:
antenna
antenna coupler (where the antenna screws onto)
Nylon spacer (this prevents the center conductor of the coupler to short onto the bracket/body/mount)
bracket or body/mount etc.
star washer
nut
the bottom has the BNC threads that the cable connector attaches.

The coupler must NOT touch the body and short to ground or it will cause faulty SWR readings.
