The Y409D-SS is a high-performance UHF 9 element Yagi antenna engineered for reliable, directional communication across the 450-480 MHz UHF band. Designed for precision signal control and efficient RF performance, this antenna is ideal for point-to-point links, base station infrastructure, telemetry systems, and critical communications networks operating within the UHF 450-480MHz spectrum.
Constructed from 304 stainless steel, the Y409D-SS is built for long-term durability in harsh outdoor environments, offering excellent resistance to corrosion, wind loading, and mechanical stress. Its square boom design provides enhanced structural rigidity and consistent element alignment, supporting stable electrical performance over time. The optimised 9-element array delivers a strong 11.5 dBd gain, enabling effective forward signal concentration and improved front-to-back ratio for interference reduction and signal clarity.
