Compact Urban Design

The HAF4025A is designed for installations where a lower antenna profile is preferred. Its approximately 3.25-inch height helps reduce interference with low-clearance areas while maintaining reliable quarter-wave performance.

It is well suited for vehicles operating around:

• Parking garages

• Urban structures

• Warehouses

• Loading areas

• Commercial facilities

• Other height-restricted environments

Quarter-Wave Coverage Pattern

A quarter-wave antenna provides broad omnidirectional coverage around the vehicle. Compared with a higher-gain antenna that concentrates more energy toward the horizon, the HAF4025A provides a more balanced signal pattern that can be useful in urban areas, uneven terrain and environments with nearby infrastructure.

Actual communication range depends on the radio system, terrain, transmitter power, antenna placement and surrounding structures.

800/900 MHz Coverage

The broad 806–941 MHz range supports compatible Motorola systems operating in select:

• 800 MHz commercial bands

• 800 MHz public-safety bands

• 900 MHz business and industrial bands

• Mixed 800/900 MHz fleet-radio applications

The antenna must match the radio’s actual operating frequencies and authorized system configuration.

Compatible Radio Families

Designed for select Motorola 800/900 MHz mobile radios, including compatible:

• XPR 4380

• XPR 4580

• XPR 5580 and XPR 5580e

• MOTOTRBO 800/900 MHz mobile radios

• Corresponding DGM and XiR mobile-radio models

Compatibility depends on the radio frequency band and Mini-UHF antenna connection. Please verify both before ordering.

Permanent Through-Hole Installation

Installation requires drilling an appropriate mounting hole through a suitable vehicle roof or other conductive metal surface. Professional installation is recommended to ensure:

• Proper antenna grounding

• Weather-resistant sealing

• Safe coaxial-cable routing

• Correct positioning on the vehicle

• Compliance with RF-exposure requirements

Important Product Distinction

The HAF4025A is a non-GPS RF antenna. It does not provide GPS reception or location tracking. Installations requiring both GPS and two-way radio coverage may need a compatible combination GPS/RF antenna assembly.
