That's good news for me! Thank you so much!

Thanks Socalgmrs! I will consider my concern addressed! I do have an antenna that is published as "no ground plane required" and as this will be mounted on the front corner of my front fender, I cant put any metal under it, other than what ever the aluminum hood may provide, (although they are not "coupled").

Thanks Steve! I do have an antenna that doesn't require a ground plane. I was just concerned about the DC grounding since I noticed the sharp points on the NMO mount and assumed it was for grounding purposes, and the coax shielding terminates on that.

Hi all, newbie here. I am preparing to install a GMRS radio in my automobile. Said automobile does not have a steel roof, rather, a molded plastic composite, (2024 Bronco). The antenna mount will be mounted to a plastic accessory that is not naturally (DC) grounded. My question is: Should I, or do I have to attach a ground strap from the body/chassis to the antenna mounting bracket. The antenna uses an NMO mount and I see that there are raised "scallops" on the t-nut part of it that I assume are designed to penetrate paint and such in order to be grounded? If I do have to use a short ground strap, I have read on the interwebs that a ferrite bead should be used to "isolate" the antenna? any direction would be greatly appreciated!
