DUAL STACKED CIRCULAR POLARIZED YAGI ANTENNA

Design Features: CY-450D rugged, all weather crossed elements, dual stacked yagi antenna is designed for circular polarization. The phase shifter cable and harness cable comes with impedance matched molded joints for low VSWR and protection against weather. When the array is mounted on the rotator, the crossed elements array makes an angle of 45 degrees with respect to horizontal plane. A crossed member will be supplied with the array for necessary mounting arrangement on a Rotator. Dual Stacked Yagi antenna can be configured to work as RHCP or LHCP selectable by inter-changing the 90 Degrees delay harness cable.

Constructions: The Dual Stacked Yagi Antenna uses a gamma matching feed, eliminating the use of folded dipole. The antenna termination uses N-Female connector fixed on the antenna dipole. The Dual Yagi Array is supplied with complete mounting hardware balanced at its center of gravity for mounting on a rotator for azimuth and elevation plane scanning. The mounting hardware supplied is of stainless steel fasteners with an aluminum cross member for stacking.
