98 cm RXTX Ka Band
Antenna System
The Skyware Global 98cm Ka Band Antenna is a rugged, commercial grade
product suitable for the most demanding applications.
NEW
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 die-cast 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 “bean 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
2-3/8” (60mm) OD installation mount.
A matched feed horn and polarizer
allows the antenna to be mated to the
Skyware Global Ka transceiver or
to a stand-alone feed assembly.
• RoHS compliant
• Precision pressed steel reflector
• Long focal length optics for low
cross-pol or beam squint
• Steel components are pre-galvanized
and powder coat painted for excellent
corrosion resistance
• All hardware meets 500 minimum salt
spray test requirements (ASTM B-117
• Fine elevation and azimuth
adjustments
• Ideally suited for Skyware Global
