Global Skyware Type 123 1.2m Class II RxTx Antenna

Global Skyware 1.2m RxTx antenna

The Type 123 1.2m Class II RxTx Global Skyware Antenna is a rugged commercial grade product suitable for the most demanding applications. The reflector is thermoset-molded for strength and surface accuracy. Molded into the rear of the reflector is a network of support ribs which strengthens the antenna and sustains its critical prabolic shape necessary for transmit performance. The reflector optics feature a long focal lenghth for excellent cross-pol performance.

The heavy guage steel Az/El mount provides a rigid support to the reflector. This mount secures the antenna to any 73-76 mm (2.88″-3.00″) O.D. mast and prevents slippage in high winds. A special powder paint process offers protection from weather-related corrosion.



  • All materials comply with EU directive No. 2002/95/EC (RoHS).
  • Long focal length optics for low cross-pol performance
  • Fine azimuth and elevation adjustments
  • Available with Ku-band co-pol or cross-pol feeds.
  • Galvanized 19 mm(.75″) O.D. side feed supprot legs and 51 mm (2″) O.D. lower feed support
  • Plated hardware for maximum corrosion resistance
  • Class II system designed for typical 2 W and 4 W Ku-band Block Up-Converters(BUC)*

* 3.6 kg or 8 lb max. weight for RF electronics(BUC and LNB)
