CPI SAT 700-70TCK Torus Multiple Band Receive Only Antenna
Simultaneous C and Ku-band linear polarized 4-port, 70° orbital arc field of view
700-70TCK Multiple Satellite RX Only
The CPI SAT (formerly GD Satcom Technologies & Prodelin) 700-70TCK Torus antenna consists of contoured, rigid aluminum panels which are parabolic in one plane and circular in the plane of satellite equatorial orbit. It is supported by a stiff steel backstructure, which is unique to each installation. The Torus antenna provides consistent high-quality RF performance across 70° of the orbital arc while utilizing a single reflecting surface. Individual feeds can be placed on a feed tray to view satellites with 2° of separation. The offset design provides a gain equivalent to that of a 7-meter parabolic antenna, while providing significantly lower sidelobes. This reduces the interference from terrestrial sources or adjacent satellites.
