SKYWARE GLOBAL ANTENNA 1.2M TX/RX KU BAND TYPE 120 CLASS I

The Skyware Global 1.2 m Type 120 Offset 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 not only strengthens the antenna, but also helps to sustain its critical parabolic shape.

The Az/El mount is constructed from heavygauge steel to provide a rigid support to the reflector. The Az/El mount secures the antenna to any 2.88" - 3.00" (73-76 mm) O.D. mast and prevents slippage in high winds. A specially formulated powder paint process offers excellent protection from weather-related corrosion.

TYPE 120TX FEATURES

  • One-piece thermoset-molded offset reflector.
  • Single bolt fine elevation adjustment.
  • Galvanized .75" (19 mm) O.D. feed support legs.
  • Factory pre-assembled mount.
  • Plated hardware for maximum corrosion resistance.
  • Available with a wide variety of C-Band or Ku-Band feeds.
