Introduction
Like all Andrew earth station antennas, the 7.6-Meter Earth Station Antenna provides
high gain and exceptional pattern characteristics. The electrical performance and excep-
tional versatility provides the ability to configure the antenna with your choice of linearly-
or circularly-polarized 2-port or 4-port combining network. That versatility is provided at
the time of initial purchase, as well as in the future, as your satellite communication
requirements evolve.
The aluminum reflector is precision formed for accuracy and strength requiring minimal
assembly. The reflector assembly is 25-feet (7.6-meters) in diameter and segmented in
a sixteen piece configuration to reduce shipping volume and facilitate transport to
remote sites. Reflector panels are chromate converted and painted with a highly reflec-
tive white paint.
The pedestal mount can be purchased with either manual or motorizable capabilities.
The mount features 180 degree azimuth coverage in three continuous 120 degree over-
lapping ranges and executes 90 degree continuous elevation adjustment. This large
adjustment range provides non-critical foundation orientation and the ability to view geo-
stationary satellites from horizon-to-horizon, from any location worldwide.
The motorizable mount features self-aligning bearings for the elevation pivots, resulting
in "zero" backlash. This mount can be operated manually, but has the ability to be
upgraded for motorized operation, including steptracking/Smartrack™ applications.
The aluminum enclosure and hot-dipped galvanized steel mount maintain pointing accu-
racy and ensures durability and reliability. The antenna and standard manual mount with
enclosure will survive 125 mph (200 km/h) wind, in any position of operation, without
damage or permanent deformation in moderate coastal/industrial areas. The antenna
will survive 200 mph (320 km/h) wind when properly stowed in the 90 degree elevation
(zenith) position.
Andrew provides a complete line of available options, including motor drive systems
(with power interfaces addressing domestic and international standards), remote micro-
processor antenna control for motor drive systems, pressurization equipment, and inter-
connecting HELIAX
® cables and waveguide.
