Skyware Global Antenna 1.2M Tx/Rx Ku-Band Type 125 Class I Low Cross-Pol

The Skyware Global Type 125TX 1.2M Class I TxRx 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 parabolic shape necessary for transmit performance. The reflector optics feature a long focal length for excellent cross-pol performance.

Description

SKYWARE GLOBAL TYPE 125 1.2M TX/RX CLASS I ANTENNA SYSTEM

The Skyware Global Type 125TX 1.2M Class I TxRx 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 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 73-76 mm (2.88″ – 3.0″) O.D. mast and prevents slippage in high winds. A special powder paint process offers excellent protection from weather-related corrosion.
