Laird GPSU15m NMO GPS Antenna

The Laird GPSU15m is an active GPS antenna designed for NMO mounting on vehicles. It serves fleet management, vehicle tracking and other location-based applications that require a durable, roof-mounted receiver. The unit operates on a 2.5 to 7 V supply and provides 26 dB of gain for reliable signal acquisition. Its black housing blends with most vehicle roofs.

Installation and common issues

The antenna fits standard NMO mounts, so installation uses a single hole and the supplied hardware. A secure ground plane on the metal roof is essential for proper performance. The most frequent problem is an insufficient voltage supply outside the 2.5 to 7 V range, which causes the active amplifier to fail. Water ingress only occurs if the O-ring seal is damaged or omitted during fitting.

Sustained operation behaviour

The fully waterproof, environmentally sealed enclosure maintains performance during continuous exposure to rain, dust and temperature extremes. The O-ring sealing protects the internal amplifier from corrosion during long-term fleet use. Signal gain remains stable at 26 dB throughout extended tracking sessions without thermal degradation. The rugged construction supports permanent outdoor mounting for the life of the vehicle.

Questions about this item

How can I confirm the GPSU15m antenna is receiving a signal after NMO installation?

The 26 dB active antenna requires 2.5 to 7 V supplied through the coaxial cable; a GPS receiver showing valid satellite lock and stable position data confirms the unit is operating correctly.

What comes with the GPSU15m and what must I source separately?

The package contains the black GPSU15m antenna with its integrated NMO base and O-ring seal; you must supply a compatible NMO-mount coaxial cable and a GPS receiver able to provide 2.5–7 V DC bias power.

Which gain and voltage version of the Laird GPSU15m should I choose for fleet tracking?

This model is a single 26 dB gain variant that operates from 2.5 to 7 V; select it when your GPS hardware can supply voltage in that range and the installation demands a fully waterproof, NMO-mount antenna.
