I looking at upgrading the antenna on my 2002 F-250. I currently have an NMO mount on a small bracket fixed in the hood gap holding a Larsen antenna. My questions: are PL-259 mounts stronger than NMO? I sometimes us this truck for off-road and encounter tree limbs. I may add an amp at some point. Do the PL-259 handle power better? The NMO had served me well, but I don’t think the little tab on the mount and contact in the antenna base are the best electrical connection. I’m considering either the Diamond SG7900 or Comet CSB line. Any thoughts?
