- LTE λ/4 External Whip Antenna
LTE / LPWA λ/4 Whip Antenna
Features
1. Excellent Antenna Performance
Despite its compact form factor, this antenna supports a wide frequency range from 698 MHz to 2700 MHz when integrated with an adequate ground plane. At 920 MHz, it achieves a radiation efficiency of –1 dB, delivering stable and reliable RF performance across LTE and LPWA applications.
2. Pre-Certified with Major Communication Modules Used in Japan
3. Ingress Protection (Water & Dust Resistant)
Each unit undergoes 100% waterproof inspection prior to shipment, verified to IPX7. To ensure reliable sealing performance, STAF Corporation developed a proprietary connector specifically for waterproof testing. The connector is designed for controlled tightening with a torque wrench, making it ideal for applications that require high mechanical reliability and environmental durability.
4. UL 94 V-0 Flammability Rated
The enclosure is molded from weather-resistant ASA resin and meets UL 94 V-0 flammability requirements. This material selection ensures long-term outdoor durability and safe operation in industrial environments.
Applications
With stable RF performance and high weather resistance, this antenna is widely deployed across demanding IoT and industrial applications.
Smart factories, agriculture & livestock monitoring devices, smart meters, bridge monitoring, tilt sensors, water level monitoring, insulation monitoring systems, parcel lockers, LTE routers & gateways, solar power systems, industrial equipment, construction equipment management terminals, marine monitoring, pest control systems, food temperature monitoring, and industrial drones.
