Quarter-Wave Coverage Pattern

The HAD4009A provides broad coverage around the vehicle. Unlike a gain antenna that concentrates more energy toward the horizon, its quarter-wave design provides balanced vertical and horizontal performance.

This makes it suitable for:

• Urban environments

• Areas with tall buildings

• Rolling or uneven terrain

• Locations with elevation changes

• General commercial and government fleet operations

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

Compatible Radio Families

Designed for select Motorola VHF mobile radios operating within 162–174 MHz, including compatible:

• CM200d

• CM300d

• XPR 2500

• XPR 4000 Series

• XPR 5000 Series

• XPR 5000e Series

• CDM Series

• MOTOTRBO DM and DGM Series

• Select GM, PM and XiR mobile radios

Compatibility depends on the radio’s exact VHF frequency range and Mini-UHF antenna connection. Please verify both before ordering.

Frequency Selection Notice

The HAD4009A is designed specifically for 162–174 MHz. Motorola VHF mobile radios may operate across a broader band, but the antenna should match the radio’s programmed frequencies.

Other Motorola quarter-wave antenna models are available for lower VHF segments, including:

• 136–144 MHz

• 144–150.8 MHz

• 150.8–162 MHz

Quarter-Wave vs. Gain Antennas

The HAD4009A is a strong choice when balanced coverage is more important than maximizing horizontal range.

A higher-gain antenna may provide additional coverage across flat terrain, but its compressed vertical signal pattern can be less effective around hills, valleys or significant elevation changes.

Permanent Through-Hole Installation

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

• Proper antenna grounding

• Weather-resistant sealing

• Safe coaxial-cable routing

• Correct antenna placement

• Verification of reflected power

• Compliance with RF-exposure requirements

Important Product Distinction

The HAD4009A is a non-GPS RF antenna intended for customers who do not require location tracking from this antenna assembly.

A separate GPS antenna or compatible combination antenna is required when GPS or GNSS reception is needed.
