    Model 1200K/1210K - RCI SNG ANTENNA SYSTEM Operation and Maintenance Manual SECTION 1 - OVERVIEW TECHNICAL DESCRIPTION The 1.2M SNG Antenna System is an elevation over azimuth positioner featuring the simple, rugged Roto-Lok® drive system which produces very low backlash, high-stiffness and high- reliability and driven by a low backlash, gear box with DC motors.
  • Page 4 Model 1200K/1210K - RCI SNG ANTENNA SYSTEM Operation and Maintenance Manual SECONDARY DRIVE SYSTEM The Az and El Roto-Lok® drive systems are driven by a low backlash worm gear set with a 40:1 ratio. The factory low backlash of the worm-gear set is reduced further by the Roto-Lok® drive ratio resulting in a lash equivalent to only .06 dB as seen by the RF system.
