STR-5.4M L/X-band Limit Motion Antenna are applied for Telemetry,Tracking&Command/Remote sensing, Deep space missions/Geodesy, Radio astronomy,which is designed and manufactured by strong. It supplies continuous stroke, high speed and accelerated velocity, as well as high pointing accuracy/tracking accuracy, the antenna allow all visible operation for GEO Satellite and LEO Satellite.

Servo drive and tracking system can supply each operation modes, all antennas can equip reflector electric heating de-icing system, include integrating infrared heating rods on the antenna reflector. Antenna pedestal support/tower pedestal can be steel structure or reinforced concrete structure. Tower pedestal can be done as a hub equipment room which can supply electronic equipment.

Except the antenna system is supplied by Strong, all transmitting/receiving electronic products can be customized by the customer; strong has a professional project management team to supply design, producing, transportation, installation, debug, and acceptance test, as well as after-sale maintenance and repair service; strong is an antenna system who provides turnkey services to the customers.
