NMO or UHF mount?

[Se7en]

For vhf uhf mobile operation, whats more desirable/efficient: NMO mount or a SO239 (UHF) mount?

I've used both but for consistency use only the SO239 now. I don't think there's any particular advantage performance wise. It's whatever antenna and mount you prefer. Not all antennas come is both versions either. I think commercial antennas are more likely to be NMO.

as you can see the last mount towards the back is NMO (anli dualband) the next is NMO (800mhz), the center of the roof is SO239. so if i bought either a comet or diamond tri band antenna since the so239 is center that might be the better choice?

Wonder if Ham City has any demo antennas they'll let you try out in the parking lot before you buy?

Bought the diamond cr320A. Haven't tried it yet....eating lunch.

I prefer nmo mounts, although my Wilson 5000 is an S0239 mount.

NMO stands for New Motorola Mount and was designed by Motorola in the late 50's, eary 60's time period for VHF and UHF mobile antennas. The mount is basically stronger, very weatherproof, lower profile, and a better impedance match at UHF. It's darned near perfect.

That's the history.

Great little history fact !
I bought a Nmo to Uhf adapter, which should be here today. The nmo seems like a stronger slick mount over a uhf "so239" mount.

Both types of mounts have limits on how large an antenna they can handle, or how much force they can be subjected to. As long as you stay within those limits either are nice mounts. I would rather use the NMO if possible, but that's not always possible. They are a bit less obtrusive inside the vehicle. Not all manufacturers make antennas that can use an NMO mount. Oh well, so use something else.

Here is the adapter in use, it is spring loaded which is nice.
