Introduction
Like all Andrew earth station antennas, the 3.7-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-
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 versatile pedestal mount can be purchased with either manual or motor-
izable capabilities. The pedestal mount features 180 degree azimuth coverage in three
continuous 120 degree overlapping ranges and executes 90 degree continuous eleva-
tion 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 pedestal 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 ES37
MPK
or ES37
MPJK
letters within
the antenna type number. The addition of the letter "J" within the antenna type number
indicates that the mount includes azimuth/elevation machine jackscrews, instead of cor-
responding azimuth/elevation strut assemblies. The azimuth/elevation jackscrews are
equipped for integration with the optional motor drive systems.
A manual pedestal mount is also available. It provides the same strong and versatile
combination of mechanical features as the motorizable version; except that the elevation
and azimuth axes are locking types, instead of bearing mounted types. This mount type
is always equipped with manual struts and a fixed mount for the separately-ordered
combining network. This mount has been designed for manual applications only and
cannot be upgraded to a motorizable mount.
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 field-installed electrical
anti-icing heaters, motor drive systems (with power interfaces addressing domestic and
international standards), remote microprocessor antenna control for motor drive sys-
tems, pressurization equipment, and interconnecting HELIAX® cables and waveguide.
