11M Antenna
The 11.0 Mtr Antenna System is a Cassegrain Antenna system and is designed for high structural stability to achieve high accuracies in pointing & tracking satellite, apart from ease in installation. The Reflectors are doubly curved and formed to high RMS accuracy of 0.5mm. The cassegrain feed consists of Conical Horn and Sub Reflector and forms Optics with the shaped Reflector and thus provides about 60% efficiency of the aperture combined with excellent side lobe level performance. 48 No's of stretch formed panels in 2 Rows are mounted on 24 No's of Radial trusses emanating from a central Hub. The central Hub is spacious enough to accommodate the Receive Electronics.
The Mount is an Elevation over Azimuth available in 3 types. The first one, a conical Mount for 360° rotation in segments of ±20°,
the second one, King post Mount with 110° continuous and 180° in two positions type, Third one with ±330° in Azimuth using a Slewing Ring gear with Bearings.
In this option we supply FAST TRACK ANTENNA SYSTEM ALSO.
The Antenna meets latest Specs of ITU-RS-580-6.
