Encl: (1) Logistics Data, Publications, and Allowances for
the Quick Reaction Satellite Antenna, OE-361(V)2/G

1. Purpose. To provide information to Fleet Marine Force
commanders relative to the Quick Reaction Satellite Antenna
(QRSA), and OE-361(V)2/G (hereinafter referred to as the
OE-361(V)2/G QRSA) and to provide instructions for placing
these items into service.

2. Cancellation. MCO 2100.6.

3. Background

a. Required Operational Capability No. CCC1.13, issued 17
June 1976, described a need for a super high frequency (SHF)
tactical satellite communication system to provide the
commander landing force with long-haul and defense
communication system communications entry, as well as
intra-landing force communications where terrestrial radios
could not provide requisite communication links.

b. The OE-361(V)2/G QRSA operates in conjunction with
various SHF satellite communication terminals to provide high
gain transmission and reception of satellite communication
data. The 20-foot diameter OE-361(V)2/G QRSA provides an
additional 8.5 dB gain over the 8-foot diameter AS-3036/TSC
Antenna provided with the AN/TSC-85A and AN/TSC-93A Ground
Mobile Forces (GMF) Satellite Communication (SatComm)
Terminals. The additional gain increases the power efficiency
of the overall communication link by allowing more information
to be passed per unit of allocated satellite capacity. In
areas near the edge of the satellite earth coverage footprint,
the additional gain of the OE-361(V)2/G QRSA will allow for




the operation of several low data rate carriers which would
otherwise not be available.

c. The OE-361(V)2/G QRSA was originally designated as a
modification to the AN/TSC-85A and AN/TSC-93A GMF SatCom
Terminals. The distribution of two OE-361(V)2/G QRSA for
each four AN/TSC-93A GMF SatCom Terminals precluded its
designation as a modification and a table of authorized
materiel control number (TAMCN) was assigned.

d. This item of new equipment will be placed in service
following the provisions of this Order.

4. Information

a. General. Fifteen OE-361(V)2/G QRSA's were procured
from the Harris Corporation, Melborne, Florida, through the
principal developing activity, the U.S. Army Satellite
Communication Agency, (SATCOMA) Fort Monmouth, New Jersey.

b. New Items

(1) The OE-361(V)2/G QRSA is a transportable,
multiple carrier, quick reaction antenna that operates in
conjunction with various SHF satellite communication terminals.
It is capable of continuous operation and is designed to
operate in climatic conditions which may be encountered in
global deployments. The antenna exhibits a low operating
profile and can be quickly erected or disassembled in 1 hour
by a crew of four in 20 mph winds. The OE-361(V)2/G QRSA
includes all subsystem elements necessary to transport,
install, and operate the antenna.

(2) The OE-361(V)2/G QRSA uses a 20-foot (6.1
meters) diameter antenna to receive left hand circular
polarized signals in the 7.25 to 7.75 GHz frequency range and
transmit right hand circular polarized (RHCP) signals in the
7.9 to 8.4 GHz frequency range. It has a maximum voltage
standing wave ratio of 1.4:1 and a minimum G/T of 26 dB at 7.25
GHz. The OE-361(v)2/G QRSA has an minimum equivalent isotopic
radiated power of 109 dBm for a transmit power of +60.4 dBm.
It can transmit up to four carriers without significant
intermodulation noise (less than -135 dBm with four 0.5kW
carriers). The OE-361(V)2/G QRSA is equipped with an
intermodulation product (IMP) free feed and a dehydrator. It
has an estimated mean time between failure of 5,000 hours, an
estimated mean time to repair of 1 hour and an estimated
maximum time to repair of 2.5 hours.

(3) One OE-361(V)2/G QRSA with mobilizer will be
supplied for each AN/TSC-85A GMF SatCom Terminal and two
OE-361(V)2/G QRSA with mobilizers will be supplied for each


2


of four AN/TSC-93A GMF SatCom Terminals. A separate 5-ton cargo
vehicle (M925), as allotted by reference (a), will be used to
transport the OE-361(V)2/G QRSA or it may be transported by the
same means as the GMF SatCom Terminal that it is used with. The
OE-361(V)2/G QRSA is transported as a towed vehicle with the
M832 Mobilizer and by air with the C-130, C-141, and C-5
aircraft.

(4) The major components of the end item are the
20-foot shaped reflector, the feed component, the antenna
positioner, and the pallet structure. Equipment data is
contained in the enclosure.

c. Training. There will be no formal training on the
OE-361(V)2/G QRSA. The Army procurement quantity was not
sufficient to warrant the procurement of the OE-361(V)2/G
QRSA new equipment training (NET) course materials or the
addition of the OE-361(V)2/G QRSA training to the Tactical
Satellite Microwave Systems Operator course at the U.S. Army
Signal School, Fort Gordon, Georgia. The OE-361(V)2/G QRSA is a
simple system with straight forward deployment and storage
procedures. On-the-job training (OJT) should prove sufficient.

d. Support and Test Measurement and Diagnostic Equipment
(TMDE). The special tools and TMDE required for each
OE-361(V)2/G QRSA are identified in the enclosure.

e. Repair Parts Support. Repair parts support for the
OE-361(V)2/G QRSA will be provided through the normal four
echelons of maintenance. The initial issue provisioning
project code for all units is B3C.

f. Technical Representation. Contractor technical
representation will not be required to maintain the OE-361(V)2/G
QRSA.

g. Maintenance Support

(1) The using unit is authorized first through fourth
echelons of maintenance. Maintenance will consist of daily
inspection, cleaning, tightening, touch-up painting, fault
isolation, and replacement of modules/equipment. Maintenance
will also consist of lubrication of gears, actuators, etc., and
replacement of reflector panels and feed elements. Piece
parts, such as lamps, fuses, and discrete components mounted on
the chassis, may also be replaced. Maintenance reporting shall
be per reference (b). The stocking of maintenance float assets
is per reference (c) and local commander's float standard
operating procedures. Supply support at the using/maintaining
unit is per reference (d).

(2) The force service support group (FSSG) will not
perform maintenance on the OE-361(V)2/G QRSA or its modules.
The FSSG will channel unserviceable equipment, and modules to
the U.S. Army depot repair facility, Tobyhanna Army Depot for

identifying the condition code of the item. Disposition
instructions will be forwarded to the Marine Corps Logistics
Base (MCLB), Albany, GA 31704-5001.

(3) The U.S. Army Communications Electronics Command
(CECOM) has been designated as the primary inventory control
activity. The U.S. Army Depot Maintenance Activity, Tobyhanna,
Pennsylvania, will accomplish all repairs beyond the capability
of organizational and intermediate maintenance. Maintenance at
this level will be accomplished by a depot maintenance
interservice support agreement (DMISA) between the Army and the
Marine Corps.

assets for 6th CommBn will be shipped to MCLB Albany for
storage under Purpose Code C pending resolution of Marine Corps
Reserve storage, manpower, and training requirements.

6. Miscellaneous Information

a. Prime Power. The OE-361 (V) 2/G QRSA mounted equipment
derives its power via cable interfaces with the SHF satellite
communications terminal. Prime power for the dehydrator and
other use is supplied via a circuit breaker on the shelter
power distribution panel. Prime power characteristics must
satisfy the following requirements:

Voltage: 120 Vac +/- 10 percent

b. One M832 Mobilizer (Dolly Set), NSN 2330-00-221-4939,
per OE-361 (V) 2/G QRSA will be shipped to using units from
MCLB Albany with each OE-361 (V) 2/G QRSA.

c. Each OE-361 (V) 2/G QRSA is provided with rubberized
canvas weather covers for outside storage.

d. The OE-361 (V) 2/G QRSA will be delivered without a Low
Noise Amplifier (LNA), NSN 5895-01-112-2360. The LNA's were
deleted from the OE-361 (V) 2/G QRSA specification in the early
1980's by CECOM/SATCOMA as a cost saving measure. Using units
must remove the LNA from the AS-3036/TSC antenna provided with
each AN/TSC-85A/93A GMF SATCOM terminal and install it on the
OE-361 (V) 2/G QRSA when the additional gain provided by the
OE-361 (V) 2/G QRSA is required. This is a temporary procedure
until additional LNA's are received in stock. Using units
must requisition a LNA for each QRSA. The LNA will be provided
by MCLB Albany when available and will be included as a SL-3
component of the OE-361 (V) 2/G QRSA.
