Hello everyone,
I usually just guest browse these forums when I have a radio issue but wanted to make an actual account to ask this one.
I have a 2m radio for which I am going to mount an NMO in a small plastic housing that mounts at the third brake light location on the rear roof of my pickup truck. I’m assuming ground plane is “ok” as I at least have a nice metal plane forward of the antenna and while not ideal due to the drop in height, I also have a metal tonneau cover that I’m guessing will act as the rear ground plane. Please correct me if I am wrong.
My question is, given that the mount is plastic, do I need some sort of grounding ring run from the NMO to the cab to ground the NMO itself? I know that NMO mounts are usually grounded to metal when they bite in with their teeth. I have heard with a 1/2 wave antenna that it doesnt really matter, but I’m not sure if that’s referring to ground plane in general or referring to grounding the actual mount so that the coax isn’t acting like an antenna.
The mount is very tight so I can’t use a metal plate or anything underneath either.
