Technical data

Like all Andrew earth station antennas, the 4.0 meter earth station antenna provides high gain

and exceptional pattern characteristics. The electrical performance and exceptional versatil-

ity provides the ability to conﬁgure the antenna with your choice of transmit/receive as well

as receive-only, and for either linearly- or circularly-polarized C-band and linearly-polarized

operation. A pedestal mount version is available for addition of motorization. The versatility is

provided at the time of initial purchase, as well as in the future, as your satellite communica-

tions requirements evolve.

The segmented aluminum reﬂector panels are precision formed for accuracy and strength. The

6-piece reﬂector panel design ensures that the assembled reﬂector will maintain the extremely

accurate surface contour and guaranteed performance without reﬂector alignment.

The versatile tripod mount features 180° of coarse azimuth coverage in four overlapping

ranges, and 90° coarse elevation adjustment. This large range of adjustment provides the

ability to view geostationary satellites from horizon-to-horizon, from any location within the

continental United States.

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 potential

to be upgraded for motorized operation, including steptracking/Smartrack™ applications.

The motorizable mount type is indicated by the ES40CM-1 or ES40KM-1 letters within the

antenna type number. 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 back structure and hot-dipped galvanized steel mount maintains pointing

accuracy and ensures durability and reliability. The antenna and mount will survive 125

mph (200 km/h) wind, in any position of operation, without damage or permanent

deformation.

Andrew provides a complete line of available options, including ﬁeld-installable electrical

anti-icing heaters, pressurization equipment and interconnecting HELIAX cables and

waveguide.

An optional hoisting kit, which precludes the use of a crane, is available from Andrew and

can be utilized as an installation tool for multiple installation purposes.
