Model 18B Crossed Yagi Antenna

The Synergetics Model 18B is a high-gain,  lightweight antenna designed to provide optimum performance for all  fixed-location, timed Satellite Data Collection Platforms (DCP's). It is also  well-suited for other 400 MHz applications. The basic 18B design consists of two  quadrature-phased, five-element Yagi antennae, orthogonally mounted on a common  aluminum boom. The driven elements are fed via a unique micro-strip matching  circuit. The combination of a precision aluminum structure driven by a  photo-reproduced matching circuit results in exceptionally uniform electrical  and mechanical performance. The antenna is supplied with screw-in elements for  ease of shipping, storage, and field installation.
