Wi‑Fi Dual λ/2 Whip Antenna

Standard

The Wi‑Fi dual λ/2 external whip antenna supports both 2.4 GHz and 5 GHz bands with an omnidirectional radiation pattern. Its half-wavelength design eliminates the need for a ground plane while maintaining stable radiation characteristics. The antenna delivers an average gain of approximately +1 dBi for reliable Wi‑Fi connectivity.

Designed for outdoor use, the housing is made of weather-resistant ASA resin. It provides IP67 ingress protection and a UL94 V-0 equivalent flame rating. Each unit undergoes 100% waterproof inspection, and secure fastening is ensured using a torque wrench for consistent installation quality. This antenna is ideal for applications requiring high reliability in demanding environments.

Features

1. Stable RF Performance – Omnidirectional antenna supporting the 2.4 GHz and 5 GHz Wi‑Fi bands.

The 1/2 wavelength design eliminates the need for a ground plane, enabling stable RF performance using the antenna element alone. The average gain across the radiation pattern is approximately +1 dBi, delivering consistent omnidirectional coverage and reliable Wi‑Fi connectivity.

2. Ingress Protection (Waterproof / Dustproof)

Every unit undergoes 100% waterproof inspection prior to shipment to verify IPX7 performance. To ensure reliable sealing, we developed a proprietary connector specifically designed for waterproof applications. The connector supports torque wrench tightening, making it ideal for high-reliability systems requiring secure mechanical fastening and stable RF performance.

3. UL 94 V-0 Flame Retardant Rating

The housing is molded from weather-resistant ASA resin and meets the UL 94 V-0 flame retardant rating. This material selection ensures long-term outdoor durability and enhanced safety in demanding industrial environments.

Applications

IoT devices, Smart Buildings, and Construction ICT systems.
