Skyware Global Antenna 1.8m Tx/Rx Ku-Band Type 180 Class I

SKYWARE GLOBAL TYPE 180TX 1.8M TX/RX KU-BAND CLASS I ANTENNA SYSTEM

The Skyware Global Type 180 1.8M Tx/Rx Class I Antenna System 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 parabolic shape necessary for transmit performance. The reflector optics feature a long focal length for excellent cross-pol performance.

The Az/El mount is constructed from heavy-gauge steel to provide a rigid support to the reflector. The Az/El mount secures the antenna to any 114 mm (4.50″) O.D. mast and prevents slippage in high winds. A specially formulated powder paint process offers excellent protection from weather-related corrosion.
