Antesky has produced 9M DBS/Ku-band Tx/Rx Limit-motion Antenna , The new 9.0M antenna that can transmit and receive Ku- and DBS-bands simultaneously,for Television Transmissions.
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 Antesky, all transmitting/receiving electronic products can be customized by the customer; Antesky 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; Antesky is an antenna system who provides turnkey services to the customers.
