Thank you for that great question. No, you do not need to remove any powder coating off the antenna mount. The ground wire is extra grounding for the coax cable not the mount itself.
Correct, we have tuned our antennas for our mounts, the long whip is a no ground plain. The ground wire is an additional ground for the coax. We have found that it helps with some of the RF interference on certain models sxs's, but we include it with all our kits.
Do I need to take some paint off at the NMO ground at the Antenna Bracket ?

Most antennas require a 'ground plane' and I don't think a vehicle ground is the same thing correct?

What is the size of the antenna nmo side ?
The red terminal is a 3/4" diameter terminal
