The ZDA 928 MHz ISM Directional Yagi Antenna is a rugged, high-performance solution engineered to maximize the potential of the 902–928 MHz ISM band, leveraging the superior physics of the 900 MHz spectrum to punch through foliage and non-line-of-sight obstacles. Designed as the backbone for mission-critical industrial networks, it provides robust connectivity for diverse applications including SCADA telemetry in utility monitoring, RFID logistics, and LPWAN backhaul for IoT gateways. Whether aggregating data from smart metering clusters or establishing stable point-to-point wireless bridges in obstructed terrain, this antenna excels at maintaining low-noise links and consistent uptime where standard equipment often struggles.

Offered in four configurations, the lineup delivers 8 to 17 dBi of focused directional gain with selectable horizontal or vertical polarization to tailor beamwidth for specific deployments. Every unit is validated using an Anritsu S331P analyzer to certify a VSWR of ≤ 1.5, minimizing return loss and safeguarding radios connected through the standard 50 Ω N-Female interface. Supporting up to 200 W of input power, the antenna maintains strong front-to-back performance to keep signals clean in noisy RF environments, all while being housed in a durable aluminum alloy structure rated for reliable, weatherproof operation in the most demanding field conditions.
