WY7023 – 23 Element 70cm Yagi Beam Antenna (432 MHz, 800W PEP)

Engineered for high-performance UHF communication, the WY7023 is a precision-built 23-element Yagi antenna optimized for the 70cm amateur radio band (432 MHz). Designed for serious operators, it delivers exceptional gain, tight beamwidth, and robust power handling, making it ideal for long-range terrestrial contacts, contesting, and EME (Earth-Moon-Earth) applications.

With a standard rating of 200W FM and a special version supporting up to 800W PEP, the WY7023 accommodates both casual and high-power setups. Its low SWR (<1.6) ensures efficient transmission, while the beamwidths of 26° horizontal and 28° vertical provide excellent directivity and signal isolation.

Built from lightweight, corrosion-resistant materials, the antenna maintains structural integrity under extreme wind conditions, with wind loads rated at 40 N (80 km/h) and 160 N (160 km/h). The compact footprint and stacking distances (1.5 m horizontal / 1.6 m vertical) make it ideal for array configurations.
