    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?

    I'd stay with NMO, and stay with Larsen, Laird, Comtelco, PCTel and alike. With the NMO you'll have a much wider selection of antennas available.

    I echo the suggestion that you stay with NMO. Many more antenna options. There is a reason why public safety vehicles typically use NMO's. They hold up better than most of the other available mounts. It isn't the mount you need to worry about when off roading--it is the antenna. There are antenna options with springs that increase survivability. I have an F 150 (slightly newer than yours) and it has had a Larson 2/70 NMO (also highly recommended) on the same type of mount you have and mine has been off road many times. The antenna has survived many a branch hit and keeps on ticking.

    +1 more for Larsen and NMO; like the old Western Airlines ads of the 1960s, it's "...the only way to fly."

    There is nmo

    And there is everything else.

    FWIW, I've been using a big Comet dual-band antenna with SO-239 style base on my car for seven trouble-free years. It works fine and has been very durable.

    BUT. . .

    As the other fellows have said, you'll never go wrong with a commercial-grade NMO mount. Just don't buy a cheap one (they will rust, the center contacts will lose their "springiness", etc). Stick with the good stuff and it'll last a lifetime. There's a reason fire, EMS, law enforcement, and the Government use them almost exclusively.
