Combined Radio and GPS Coverage

The RAD4214A combines a VHF communication antenna and GPS antenna into one vehicle-mounted assembly. It supports two-way voice and data communication while providing satellite reception for compatible radio location and fleet-tracking features.

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

Reliable 1/4-Wave VHF 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, suburban and varied-terrain environments.

Its frequency-specific design is optimized for radios operating between 136 and 144 MHz, making correct frequency matching essential.

Permanent Through-Hole Installation

The RAD4214A 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 VHF performance.

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

Radio Compatibility

The RAD4214A is compatible with select GPS-capable Motorola VHF mobile radios that operate within the supported frequency range and use the appropriate Mini-UHF connection.

Compatibility depends on:

• The radio’s exact VHF frequency split

• GPS capability

• Antenna connector type

• Radio programming and location-service configuration

Confirm all compatibility requirements before ordering.

Important GPS Requirement

The connected radio must support GPS functionality for the integrated GPS portion of the antenna to operate. GPS tracking features may also require proper radio programming, compatible dispatch software or an active location-services configuration.

Why Choose the Motorola RAD4214A?

The RAD4214A combines frequency-specific VHF communications and GPS reception in one professional antenna system. It is an excellent choice for fleets requiring reliable 136–144 MHz coverage and vehicle location reporting without installing separate antennas.
