Global Skyware 1.2m SFL Receiver Transmitter (RxTx) Antenna

The 1.2m 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 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 (73-73MM) 27/8 or 3” 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 90dB or better

Class I system designed for typical lightweight Ku-band RF Electronics (2.0 kg or 4.5 lb max. weight (For BUC and LNB) 2.2 kg or 4.8 lb max. weight (For Transceiver)).

Features:

• One-piece precision SMC Reflector
• Precision Az/EI Mount
• Fine Azimuth and Elevation adjustment features
• All materials comply with EU Directive No. 2002/95/EC
• 720 hour salt spray hardware
• Standard waveguide flange interface
