Description
1.8 Meter Ka-Band Rx/Tx Antenna System
The Skyware Global Type 1815 – 1.8 Meter Ka-Band Rx/Tx Antenna System is a rugged commercial grade product suitable for 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 that strengthens the antenna and helps to sustain the necessary parabolic shape. In addition, the reflector optics feature a long focal length for excellent cross-pol performance.
The heavy-gauge steel Az/El mount secures the antenna to any 127-141 mm (5”-5.56”) mast and prevents slippage in high winds. In addition, a unique powder paint process offers excellent protection from weather-related corrosion.
Global Skyware designs and manufactures the antenna solutions that enable the world’s leading communications equipment companies to deliver data via satellite. They offer solutions for Very Small Aperture Terminal (Data over Satellite (DOS)/VSAT), Satellite Broadband, or direct-to-home TV connectivity.
