Reliable VHF Mobile Coverage

The HAD4007A is optimized for mobile radios operating within the lower-middle portion of the VHF band. Its omnidirectional radiation pattern helps provide balanced communication coverage around the vehicle, making it suitable for daily fleet and field operations.

Permanent Through-Hole Installation

This antenna is intended for permanent installation through a suitable metal vehicle surface. Mounting it near the center of a metal roof generally provides the strongest ground plane and most consistent radiation consistent radiation pattern.

Professional installation is recommended to ensure proper mounting, weather sealing, cable routing and overall radio performance.

Radio Compatibility

The HAD4007A is compatible with select Motorola VHF mobile radios, including appropriately configured MOTOTRBO, APX and legacy Motorola mobile models.

Compatibility depends on the radio’s exact frequency split and antenna connection. Confirm that the radio operates within the antenna’s supported VHF range before ordering.

Important Frequency Notice

Motorola accessory listings commonly identify the HAD4007A for 146–150.8 MHz, while certain Motorola technical documents list its lower limit as 144 MHz. Customers requiring operation below 146 MHz should confirm compatibility with Delmarva Communications or Motorola before purchase.

For systems operating from 150.8–162 MHz, consider the Motorola HAD4008A. For systems operating from 162–174 MHz, the HAD4009A may be the correct alternative.
