I want to put my scanner antenna back on my car without killing the paint with a mag mount or putting holes in it. Anyone have suggestions for a good mount for a 2016 Charger Black Dual Band Antenna?
Mag mount is your only option if you don't want to mar the paint. Every other option requires clamping a mount to the edge of a body panel (the clamp screws have to pierce the paint to get a connection for proper grounding), or drilling holes.
A mag mount does minimal damage to paint if both the mount and the paint are clean. Any dirt will get crushed into the paint and mar the surface.
I would suggest a fender bracket mount:

You can put sealant on the mag mount base to prevent water intrusion. If that is not an acceptable option, then your only option is to drill hole(s). And you'll still need to apply sealant around the mount.
Are these ok mounts? http://www.theantennafarm.com/catalog/tram-1246b-1571.html
I have used trunk lip mounts for years and have never marred the external finish. It does however dig the two set screws into the under side of the trunk lid to complete the ground but so what.
