Introduction
Like all Andrew earth station antennas, the 5.6-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 18.3-feet (5.6-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 versatile tripod mount can be purchased with either manual or motorizable capabili-
ties. The tripod mount features 180 degree azimuth coverage in three continuous 120
degree overlapping ranges and executes 90 degree continuous elevation adjustment.
This large adjustment range provides non-critical foundation orientation and the ability to
view geostationary satellites from horizon-to-horizon, from any location worldwide.
The motorizable tripod 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 motorizable mount type is indicated by the ES56 or ES56HS letters within the
antenna type number. The addition of the letter "HS" within the antenna type number
indicates that the mount includes High-Speed azimuth/elevation machine jackscrews,
instead of corresponding azimuth/elevation strut assemblies. The azimuth/elevation
jackscrews are equipped for integration with the optional motor drive systems. A cross-
axis grounding kit is supplied with each mount to ensure electrical interconnectivity of
the complete structure.
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. Severe condi-
tions require additional protection.
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.
