Combined Radio and Location Coverage

The PMAE4031B combines a UHF communication antenna and multi-constellation satellite antenna into one vehicle-mounted assembly. It supports two-way voice and data communication while providing GNSS reception for compatible radio location and fleet-tracking features.

This combined design creates a cleaner installation and requires less mounting space than separate UHF and GPS antennas.

Reliable 1/4-Wave UHF Performance

The antenna’s 1/4-wave design produces an omnidirectional signal pattern that provides balanced communication coverage around the vehicle. This makes it well suited for urban areas, varied terrain and environments containing buildings or other signal obstructions.

Its frequency-specific design is optimized for radios operating between 450 and 470 MHz, making correct frequency matching essential.

Multi-Constellation GNSS Reception

The PMAE4031B supports multiple global navigation satellite systems, including:

• GPS

• Galileo

• QZSS

• GLONASS

Multi-constellation support can improve satellite availability for compatible radio location, fleet-monitoring and tracking applications.

Permanent Through-Hole Installation

This antenna is designed for permanent installation through a suitable metal vehicle roof or trunk surface. Mounting near the center of a metal roof generally provides the strongest available ground plane and the most consistent UHF performance.

Professional installation is recommended to ensure proper placement, weather sealing, cable routing and connector installation.

Radio Compatibility

The PMAE4031B is compatible with select GPS/GNSS-capable Motorola UHF mobile radios that operate between 450 and 470 MHz and use the appropriate Mini-UHF connection.

Compatibility depends on:

• The radio’s exact UHF frequency split

• GPS or GNSS capability

• Antenna connector type

• Radio programming and location-service configuration

Confirm all compatibility requirements before ordering.

Choosing the Correct Gain

The PMAE4031B’s 1/4-wave design provides broad vertical coverage for urban areas and varied terrain.

• Choose the PMAE4031B for balanced omnidirectional coverage

• Choose the 3.5 dB PMAE4033B for mixed urban and highway operation

• Choose the 5 dB PMAE4034B for extended coverage across flatter, more open terrain

Why Choose the Motorola PMAE4031B?

The PMAE4031B combines reliable 1/4-wave UHF performance and multi-constellation satellite reception in one professional antenna system. It is an excellent choice for fleets requiring dependable 450–470 MHz communication and vehicle location reporting without installing separate antennas.
