Well that does make sense now that I think about it! I just assumed in order for it to bounce off and receive it would need to have a direct mechanical bond to the plane. So I should be good there. Now maybe I need to investigate the combine mounting because I’m not sure that the fiberglass rooftop that the NMO is mounted to there is a good option. I’m sure they have a ground plane under it but I would think a metal surface up top would be better

Hey everyone. Had a quick question about using one of the dreaded magnetic hockey puck NMO mounts in my 17 F350 which is of course aluminum. Obviously magnet won’t stick to the top of the cab so I’ve put some felt down with double sided tape to stick it there for my ground plane. question is the felt and double sided tape interfering with good grounding of the antenna? I really don’t want to screw anything through the top of my cab to secure the antenna mount to. Right now radios work in excess of 5 miles but if somehow fixing this would get me some more miles that would be great. I don’t have an SWR meter to check any of the specifics. Just bought MXT500 radios for farm use so communicate is kinda important at times. what’s everyone done to remedy the aluminum cab issue? Thanks I’m new here btw so bear with me as I learn these things. We’ve had business band radios for years but they have stopped working and now going another direction since we can’t fix and program our own radios. WSJV395
