Overview
The Skyware Global 1.8m BSS Band Antenna SFL RxTx Class I is a rugged, commercial quality product suitable for the most demanding applications.
The reflector is constructed from glass fiber reinforced polyester [SMC] for strength and accuracy. A proprietary process developed by Skyware Global insures high RF reflectivity as needed for Ku Band operation.
The precision Az/EI mount is made of galvanized steel for excellent corrosion resistance. This mount includes special features to increase pointing accuracy with low backlash and lockdown error.
This Az/EI allows the antenna to be installed on standard (114mm) 4.50” OD installation mounts.
All hardware is plated to 720 hour salt spray standards under ASTM B-117.
Cross-Polarization Isolation of 30dB on axis
Excellent Tx Port-to-Port Isolation of 80dB or better
Meets or exceeds regulator agency requirements
