Overview
The Skyware Global 69cm Rx/Tx Ka-Band Antenna is a rugged, commercial grade product suitable for the most demanding applications.
The pressed steel reflector assures the surface accuracy needed for Ka-band performance. Pre-galvanized steel with a powder coat finish guarantees excellent corrosion resistance and long life.
The pressed steel back structure provides for precision alignment of the reflector and support of the RF assembly without distortion.
The reflector optics incorporate a long focal length for excellent cross-pol discrimination or “beam squint”.
The heavy gauge steel Az/El mount provides a rigid support for the antenna and incorporates precise fine elevation and azimuth adjustment.
This Az/El allows the antenna to be installed on any standard 2” (51mm) or 2 3/8” (60.3mm) OD installation mount or mast depending of customer requirements.
