    Default NMO Mount Recommendations

    What do the knowledgeable folks on here recommend for NMO mounts? I will be equipping ten HMMWVs with a mix of Vertex and XTL5000s.

    Right now I'm looking at the Maxrad / PCTEL NMO58UPL https://www.talleycom.com/viewProduc...um=MXRNMO58UPL and the corresponding one with a PL-259 connector for the Vertex radios. I'm curious how they'll stand up to water / sun exposure on both sides as the mounts will be on L brackets in the truck beds.

    I'm not trying to overthink this too much, just wanted to pick everyone's brains and gather some recommendations from folks that do this professionally.

    Thanks!

    millions use the mounts. If you are concerned about corrosion I suggest you place a small amount of silicone (transparent) on the bottom part of the mount and smear a bit of dielectric grease over the installed screws to keep them from corroding.

    I've got a couple dozen of these on a bracket off the front mirror mount on interstate motorcoaches. The coax connection on the bottom of the mount isn't weatherproof. I filled up the plastic shield over the coax connection with some silicone, and they've held up for the past few years. On ones that weren't siliconed, either the center conductor came off, or the shield absorbed water and corroded apart.

    I've switched to the Larsen NMOKHFUD mount, as the coax connection is a bit more sturdy in my opinion.

    It is a fine thing to be honest, but it is also very important to be right

    Seconded. These are weatherproofed, whereas a standard NMO mount in a L bracket is not.

    Depending on how sturdy you need them to be you might consider using a bulkhead mount like the one Astro Spectra posted with half of a "trucker" style mirror mount. You can seal the connector underneath the mount with double-wall adhesive heatshrink, cold shrink, mastic and Scotchkote, vapor wrap, or whatever to keep water out.

    Thanks for the replies everyone!

    Those NMO bulkhead mounts that Astro Spectra posted look like they may be promising. The application is military HMMWVs (humvees) being used as firefighting brush trucks / quick attacks. So they need to survive their environment *and* their operators.

    Now to see if I can get the beancounters to buy off on these. Since inheriting this project, I've used my own programming cables and bought a few XTL-series mics, but personal purchase for 10 of these mounts is a bit outside of my wallet.
