VHF NMO Antenna for Mobile Radio

The usbroway VHF NMO antenna covers the 136-174 range with a 17.9in whip and 2.5dBi gain. It handles up to 150Watt input and maintains a VSWR below 1.5. The kit includes a 13.1ft RG58 cable terminated in a PL259 connector plus an L-shape stainless-steel bracket for fender mounting. It is aimed at operators who need a durable VHF whip for mobile two-way radio use.

Integration with Vehicle and Radio

The NMO base mates directly with the supplied stainless-steel bracket, which bolts to a fender or similar flat surface without requiring large cut-outs. The 13.1ft RG58 run reaches most cabin-mounted transceivers while the PL259 plug fits standard mobile radio antenna ports. Compatible brands include Motorola, Kenwood, Icom, Vertex, Yaesu, TYT and HYT units operating on VHF. The bracket’s corrosion-resistant steel frees the installer from frequent re-tightening or early replacement.

Behaviour Under Continuous Transmission

At the rated 150Watt maximum the antenna sustains a VSWR under 1.5 across the band, limiting reflected power during long key-down periods. The 2.5dBi gain provides consistent coverage without relying on high-angle lobes that fade in rolling terrain. Stainless-steel hardware resists vibration-induced loosening and salt-spray corrosion, keeping electrical contact stable over extended mobile duty cycles. Buyers needing UHF coverage or a shorter whip for garage clearance should look elsewhere.

Questions about this item

What power limit does the 150W rating impose during long transmissions?

The antenna handles up to 150W input, so the radio must not exceed that level or the whip can overheat and degrade.

How hot or noisy does the stainless NMO mount get on a 13.1ft cable run?

The mount is passive metal; it produces no noise and only warms slightly from conducted RF, staying near ambient temperature.

Which connector must the mobile radio already have for the PL259 plug?

The radio needs a UHF female jack to accept the PL259 male connector on the 13.1ft RG58 cable.
