The ZDA 430 MHz UHF Collinear Omnidirectional Antenna (ZDAQJ430) delivers robust, 360° communications for LMR, telemetry, SCADA, and industrial wireless networks across the 430–450 MHz band. With 3 configurations offering up to +7 dBi, the ZDAQJ430 omnidirectional antenna enhances coverage and link quality for base stations, industrial monitoring hubs, and distributed receiver networks. With vertical polarization, broad beamwidth, and a 50-ohm architecture, it is optimized for seamless integration into a range of critical wireless infrastructure environments.
Built to endure demanding outdoor and industrial conditions, the ZDAQJ430 features a resilient fiberglass radome and zinc-plated carbon steel mounting hardware, ensuring long-lasting performance and resistance to environmental challenges. Each antenna is tested to a VSWR ≤1.7 for minimized return loss, supporting high operational efficiency at up to 200 W input power. The N-Female connector and versatile mounting support (Ø30–Ø100 mm) enable quick, secure installations on various mast types.
