SATCOM ANTENNA

Design Features CY-225-406D rugged, high gain, all weather crossed elements dual stacked yagi antenna is designed for satellite communication (SATCOM) application with right hand circular polarization. When the array is mounted on the rotator (not supplied), the crossed elements array makes an angle of 45 degrees with respect to horizontal plane. A crossed member is supplied with the array for necessary mounting arrangement on a Rotator. Dual stacked circular polarized yagi array can be used with most tactical Multi-Band, Multi-Mode Receivers (MBMMR) and ground transceivers that accept 50 ohms antenna impedance.

Constructions The dual stacked yagi antenna uses a 6063T6 ultra corrosion resistant architectural aluminum alloy and supplied with powder coating to protect it further from severe environment conditions. 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 marine grade stainless steel fasteners with an aluminum cross member for stacking. If user does not have rotator, a crossover mounting plate to mount the antenna on top of the mast can be supplied.
