13.5 M Antenna
The 13.5 Mtr Antenna System is a Cassegrain Antenna system and is designed for high structural stability and to achieve high accuracies in pointing & tracking satellites, apart from ease in installation. The Reflector panels 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. 80 No's of Precission formed panels in 3 Rows are mounted on 32 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 mount with 360° rotation in continuous having Slewing Ring gear with Bearings.
The Antenna meets latest Specs of ITU-RS-580-6.
