HD4-2400 (Heavy-Duty 2.4 GHz Wi-Fi)

Impact-Resistant 2.4 GHz WiFi Antenna


The HD4-2400 is a low-profile 2.4 GHz Wi-Fi antenna built for exposed equipment where impact, vibration, and weather can shorten antenna life. Ground-plane-independent operation and an IP67 overmolded housing support flexible installation on precision agriculture, industrial IoT, fixed machine-to-machine, and mobile platforms.

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

Product Description

The HD4-2400 is a heavy-duty, low-profile Wi-Fi antenna designed for equipment where a protruding antenna would face repeated contact, vibration, and weather exposure. It provides omnidirectional coverage across 2400–2485 MHz for 2.4 GHz Wi-Fi networks used in precision agriculture, industrial IoT, fixed machine-to-machine, and mobile systems.

At only 0.60 inch high, the overmolded dome stays close to the mounting surface to reduce its exposure to impact. Ground-plane-independent operation also gives system designers more placement flexibility because performance does not depend on a separate metal ground plane. The 4 dBi element distributes coverage around the installation through a 360-degree horizontal beamwidth.

A UV-stable polyamide housing and IP67 rating help protect the antenna from sunlight, dust, and water when properly mounted. EN 61373, IEEE 1478, and MIL-810G shock and vibration qualifications support a longer deployment life on working equipment. The threaded stud and integral three-foot LL-195 cable provide a compact installation package for demanding fixed or mobile applications.
