- General
ANTESKY1.8m Auto Acquire Drive Away SNG Antenna which made of first grade standard carbon fiber material has much lither weight, better aerodynamics performance and stronger rigidity than other congeneric products in market. ANTESKY 1.0m/1.2m/1.5m/1.8m/2.4m auto deploy driveaway antenna system is applied to transmit C/X/Ku/Ka band data info. Compact pedestal design makes HPA /BUC installation available and reduces the signal loss in waveguide. Meanwhile, you can add the system capacity, 1.8m Auto Acquire Drive Away SNG Antenna is adaptive for 1:1 redundant HPA and BUC system.
