SKYWARE GLOBAL 1.2M KA-BAND TX/RX ANTENNA SYSTEM
w/Feed Horn, Polarizer, OMT Filter (AN121KAC202MC)
The Skyware Global l .2m Ka Band Antenna 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 Ko 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 89mm [3.5") OD installation mounts.
All hardware is plated to 720 hour salt spray standards under ASTM B-117.
Designed for use with the Skyware Global line of Ka-band transceivers with matched feed horn & polarizer.
- One-piece precision SMC Reflector
- Precision Az/El Mount
- Fine Azimuth and Elevation Adjustment Features
- All Materials Comply with EU Directive No. 2002/95/EC (RoHS]
- 720 Hour salt Spray Hardware
- Designed for Skyware Global Ka-Band Transceivers
