The ZDA 900 MHz ISM Collinear Omnidirectional Antenna (ZDAQJ900-11) is engineered for reliable 360° connectivity across the 902–928 MHz band, supporting industrial SCADA, telemetry, IoT/IIoT, and private wireless networks. Delivering up to +11 dBi of gain, the ZDAQJ900-11 extends range and improves site-wide coverage for gateways, base stations, and remote monitoring locations. At 3010 mm (9' 10.5") tall, it’s our tallest omnidirectional antenna, built to maximize elevation and deliver exceptional reach in demanding outdoor deployments.
ZDAQJ900-11 features a durable fiberglass radome and dual-pole stainless steel mounting hardware for long-term outdoor performance in harsh environments. Each antenna is tested to VSWR ≤ 1.5 to minimize signal reflection and maintain strong link efficiency across the ISM band. With an N-Female connector, and wind survivability up to 135 mph, the ZDAQJ900-11 is built for fast deployment in mission-critical field installations.
