Description
Twenty-four different 3.7-meter split and solid reflector an-
tenna models are available. The Type ES37MPJK Series
antennas have a motorizable mount with machine jack-
screws, the Type ES37MPK Series antennas have a mo-
torizable mount with pipe struts, the Type ES37K Series
antennas have a manual pedestal mount and the Type
ES37 Series antennas are mountable to a 6 inch nominal
customer-supplied pipe.
Type ES37K-124W
includes a large hub enclosure, manu-
al pedestal mount, azimuth and elevation strut kit, subre-
flector subassembly, subreflector strut kit, azimuth and ele-
vation hand crank kit, 2-port combiner network, wide-band
feed horn assembly, circular waveguide assembly, 3.7-
meter split reflector assembly and various hardware kits
for assembly. This antenna model can be deployed in the
field with minimal testing of G/T as a fully-certified
INTELSAT standard E-2 under INTELSAT registration
number
IA012A00.
Further testing has allowed these 3.7-meter antennas to
be offered as E-2 approved antennas with a 65K LNA, see
the electrical performance chart on page 2.
Type ES37K-124W-25
includes all of the above men-
tioned components and an LNA/reject filter kit that is guar-
anteed to have a G/T of 29.8 dB/K at 11.0 GHz and at a
10° elevation. This antenna system can be deployed in the
field as a fully-certified INTELSAT standard E-2 under
INTELSAT registration number
IA012AB0.
Type ES37MPJK-124W
is the same as Type ES37K-
124W but is mounted on a motorizable mount and
includes jackscrews for motorized operation. The
INTELSAT registration number is
IA012A00.
Type ES37MPJK-124W-25
is the same as Type ES37K-
124W-25 but is mounted on a motorizable mount and
includes jackscrews for motorized operation. The
INTELSAT registration number is
IA012AB0.
Type ES37( )K-4124W
is the same as Type ES37( )K-
124W but incorporates a four-port combining network. The
INTELSAT registration number is
IA012B00.
Type ES37( )K-4124W-25
is the same as Type ES37( )K-
124W-25 but incorporates a four-port combining network.
The INTELSAT registration number is
IA012BB0.
Introduction
Andrew Corporation announces final INTELSAT E-2 Type
Approval of it’s 3.7-meter Ku-band earth station products.
This first ever E-class type approval by INTELSAT followed
extensive factory testing witnessed by COMSAT,
INTELSAT’s U.S. Signatory.
By specifying an Andrew INTELSAT Type Approved
E-2 3.7-meter product savings as high as $10,000 per
antenna in field testing are realized and the system turn-
on is expedited without the need of on-site engineers to
conduct testing. This may require coordination with each of
the INTELSAT signatories depending on the region.
Andrew also offers a complete line of Ku-band E-2 and
E-3, C-band F-1, F-2, F-3 and B standard INTELSAT
antennas and can provide on-site or in-factory testing of
these products whether they be fixed or transportable.
Contact your Andrew sales representative for further de-
tails on how to implement these new type approved an-
tennas into your next project.
Attached are typical patterns measured during the wit-
nessing of the Type Approval phase II testing.
The entire test report is filed with either INTELSAT,
COMSAT, EUTELSAT or ASIASAT. Other signatories can
request copies thru ESA Product Line Management.
