HD3-915 (Heavy-Duty 915 MHz ISM)

Heavy-Duty 915 MHz ISM Antenna


The HD3-915 is a low-profile, ground-plane-dependent antenna for 902–928 MHz ISM and RFID equipment in exposed installations.

  • Covers 902–928 MHz with 3 dBi peak gain.
  • Keeps installed height to 0.625 inch in a black IP67 ASA dome.
  • Includes a one-foot RG-58 pigtail with an SMA plug.

Customization: Cable type, cable length, and connectors can be configured for specific installation requirements.

Product Description

The HD3-915 brings 902–928 MHz ISM coverage to fixed equipment that needs a compact antenna with a heavy-duty exterior. The vertically polarized element provides 3 dBi peak gain for compatible M2M and RFID systems.

A 5/8-18 threaded stud secures the antenna through the mounting surface, and the design uses the installation ground plane. The IP67 ASA housing protects the element in industrial settings.

Ideal applications:

  • 915 MHz industrial telemetry
  • Fixed RFID and M2M equipment

Example Model Configurations: HD3-915-3C-BLK-36
