The above picture is generic in nature and will be changed as per the specs complied.

The 3.8 M Antenna System can be used as Receive Only / Rx & Tx in a wide applications. TheAntenna is used as VSAT for DAMA, TDMA applications in C, Ext C & Ku Bands and as Hub station tosupport number of VSATs. The Reflector comes in 3 versions. 1st is a Prime Focus Aluminium reflector withprime focus feed, the 2nd with Gregorian feed & Aluminium reflector and the 3rd with offset type with foursegment GFRP reflector. The Antenna mount also comes in 2 versions, penetrating type, mostly used inGround installations and the other Non-penetrating type, which can be Mounted on the roof tops or on theground. Cement concrete ballast of about 2000 Kgs are to be placed over the base to resist uplift forces. For
