Control, Teletype, Telegraph, etc.). Then deter-
mine the type of end device to be used (coal-
man battery telephone, V.H.F. base station,
duplex teletype, etc.). When these three itegs
have been decided the Application Table arl-
allies you to select the proper Channel Facig

APPLICATION
DESCRIPTION
El
The channel selector assigns each channel
a slot in the microwave transmission and
keeps multi-channel information separated
throughout the system. The channel selector
is an entirely passive device consisting of a
Description continued on next page...

... Description continued
resistor network and a coupling capacitor
mounted on a non-keyed socket. This as-
sembly is covered by an aluminum can 11/2
inches in diameter and 4 inches high. The
can is marked with the assembly model
number and the channel designation cov-
ered by the assembly. Only four different
selector assemblies are required to provide
complete 25 channel selection. Channel
changes are accomplished simply by ro-
tating the selector assembly until the de-
sired channel designation is aligned with
an index mark on the wiring duct. Two
identical channel selector assemblies are
supplied with each Channel Facility. One is
for the modulator or transmission side of
the channel and one is for the demodulator
or receiver portion.
The channel unit contains its own power
supply and performs the dual function of a
modulator and demodulator in one chassis.
It accepts information from the end device
generating the intelligence . . . telephone,
teletype, data transmitter, etc.... and pre-
sents it to the radio equipment for transmis-
sion. At a receiving end the channel unit re-
moves the information, that is intended for
that station, from the radio equipment and
presents it to the end device corresponding
to the originating transmitting device.
Termination units are designed specifically
to provide the necessary hybrids, signaling
relays, connecting blocks and other circuitry
necessary to match various end devices to
the channel unit. The termination unit con-
sists of two parts: a basic chassis which pro-
vides the common circuits and connecting
blocks to enable connection to the channel
unit, and a module which provides the
signaling relays, connections and circuits
necessary to allow connection of particular
end devices to the channel units. This type
of construction allows easy and rapid con-
version of channels to meet permanent
changes in system requirements and to sat-
isfy a need to temporarily change system
loading to meet seasonal or operational
peaks. Such changes in channel allocation
may be made without interrupting systems
operation. When special requirements arise
for channel usage, the design of the neces-
sary circuits to meet these requirements is
facilitated by the module concept.
TONES
The Application Table shows how services such
as Teletype, Telemetry, Supervisory Control and
Telegraph are applied to a microwave carrier
when these functions are assigned one function
per channel. This type of operation is often de-
sired and holds advantages for systems where
channel loading is not a problem. However, if a
system is to be heavily loaded, individual micro-
wave channels may be sub-multiplexed through
use of tones to provide multiple functions on one
channel. This sub-multiplexing is accomplished
through the use of tone equipment to generate
a signal within the voice channel that may be
used to carry Teletype, Telemetry, Supervisory
Control, Telegraph and other types of informa-
tion while using only a small portion of the chan-
nel for each function. It is possible to put 15 to
18 different pieces of information on the same
channel. A 4-Wire continuously inserted Channel
Facility is used whenever sub-multiplexing is de-
sired. Tone equipment such as General Electric
Type 8 or Type 10 Frequency Shift Tone or Type
9 AM Tone can be used to supply these sub-
carriers. Such application enables maximum use
of each individual channel. This in turn permits
maximum system loading. For application data
on tone equipment refer to General Electric bul-
letins ECM32A, ECR321B, ECR322A, ECR323A,
ECR324A, and ECR326A.

General Electric 2 KMC Microwave is designed to
provide a wide range of communication facilities with
maximum dependability.
Standard assemblies are Terminal, Multiplex Re-
peater and RF Repeater Stations. Details of these
assemblies are shown in this series of descriptive
bulletins.
Standard 2 KMC Microwave equipment type UA-
1-D operates in the F.C.C. designated bands of 1700
to 1850 MC and 1850 to 1990 MC.
Standard equipment has provision for 25 Voice
communication channels, or 375 Supervisory, Tele-
metering, Teletype or other Data and Control channels
or 125 Protective Relaying channels or a combination
of these facilities.
APPLICATION
Terminal Equipment is utilized at the terminating
ends of a microwave system. If additional stations are
required between the two end points of a system they
usually take the form of Multiplex Repeater or RF
Repeater Stations. To provide microwave spurs from
a system, Microwave Terminal Equipment is combined
with Microwave Multiplex Repeater Equipment to form
a Junction Station.
DESCRIPTION
The General Electric Type UA-1-D Microwave Ter-
minal station is supplied as a complete functional as-
sembly with the basic radio frequency and multiplex
equipment. The basic station is wired for and equipped
with the following equipment:
Primary R.F. Transmitter
Primary R.F. Receiver
Primary R.F. Power Supply & Control
Basic Multiplex Units
Basic Multiplex Power Units
Wiring duct for 1 to 17 channels
Duplexer
In addition the assembly will accommodate optional
items A through J. These options may be supplied at
the time of initial installation or at any time thereafter
since the basic stations are wired to accommodate
additional units with no changes to equipment wiring.
All interconnection wiring is available through the
wiring duct and can be exposed for servicing by
removing the 3 duct covers shown in illustration above
front side.

EQUIPMENT ILLUSTRATED -
In addition to the basic equipment, various optional functions are
available to increase the utility of the system:
The RF Standby Option ?Includes the necessary RF equipment
to provide the basic terminal with standby RF equipment which is
automatically placed in operation upon failure of the primary equip-
ment. The standby equipment comes into operation 45 seconds after
failure of the normal equipment unless the standby equipments are
continuously energized, in which case the transfer is accomplished in
20 milliseconds.
The Alarm Recording Option ? Includes the necessary equip-
ment to detect and make a permanent record of station and function
codes received. Provision is made for the operation of a remotely
located 115 v alarm annunciator during the reception of an alarm.
This option may be mounted in the basic station or in a separate rack
or cabinet at some remote point if specifically requested.
VI The Alarm Transmit Option ?Includes the necessary equipment
to encode and transmit the station identifier code and up to 6 function
codes. Normally, one of these codes is assigned to indicate operation
from auxiliary or emergency power and another to indicate restoration
of primary power. Another of these codes is normally used to indicate
transfer to RF standby when this option is elected. Thus, depending on
the system, 2 or 3 fault codes are unassigned and may be wired by
the user for such items as tower light failure, illegal building entry
or any other function he chooses.
The Service Channel Option ? Includes the necessary equip-
ment to provide a service channel telephone facility with push-button
20-cycle signalling. The telephone included is a standard desk type
instrument with push-to-talk and ring out button and requires two wires
for voice and two wires for signalling between microwave terminal and
telephone. A source of talking (48 volts DC) and ringing (20 cycle AC)
voltages must be available. (If specified, a wall-type telephone instru-
ment may be substituted.)

The terminal cabinetry consists of two racks, 22", separated by a
wiring duct. Mounted in the racks are the basic units previously listed
in "Description" in addition to the optional items described below.
I3 The Power Amplifier and Cabling Option ?Includes the nec-
essary equipment to increase the power output of the standard pri-
mary transmitter in the basic terminal by 6 db, to 80 watts. This option
is applied only to the primary RF. Thus when operating from standby
RF, the power output is reduced by 6 db until restoration to the pri-
mary RF is made.
The Diversity Reception and Overlay Cabling Option ?
Includes the necessary RF equipment, less antennas and transmission
line, to equip the basic terminal for space diversity reception. This option
uses the Primary Receiver, and an additional Diversity Receiver, a Re-
ceiving Combining Unit and a Diversity Power Supply. Mounting spaces
are identified above.
rg Channel Expansion Option ? The basic assembly provides wiring
for 1 to 17 channels. This option provides the wiring for 8 additional
channel facilities.
gi Channel Unit Option ? In the basic assembly, wiring is pro-
vided for 1 to 17 channel units. After Option G is added, a total of
25 can be accommodated. See accompanying Multiplex Bulletin for
further details on channel facilities.
fl Termination Unit Option ? In the basic assembly, wiring is pro-
vided for 1 to 17 termination units. After Option G is added, a total
of 25 can be accommodated. See accompanying Multiplex Bulletin
for further details on termination facilities.
In addition the assembly will accommodate optional items A through J.
These options may be supplied at the time of initial installation or at any
time thereafter since the basic stations are wired to accommodate addi-
tional units with no changes to equipment wiring. All interconnection
wiring is available through the wiring duct and can be exposed for
servicing by removing the 3 duct covers shown in illustrations above.

General Electric 2KMC Microwave is designed to
provide a wide range of communication facilities with
maximum dependability.
Standard assemblies are Terminal, Multiplex Re-
peater and RF Repeater Stations. Details of these as-
semblies are shown in this series of descriptive bulletins.
Standard 2 KMC Microwave equipment Type UA-1-D
operates in the F.C.C. designated bands of 1700 to
1850 MC and 1850 to 1990 MC.
APPLICATION
RF Repeater Equipment is utilized at stations be-
tween the end terminals of a system where only service
and alarm channel facilities are required.
If additional channel facilities are required other
than service and alarm, then Multiplex Repeaters must
be installed at these locations. See accompanying
bulletin on this station arrangement. RF Repeaters can
be converted with ease to Multiplex Repeater stations.
DESCRIPTION
The General Electric Type UA-1-D Microwave RF
Repeater station is supplied as a complete functional
assembly with the basic radio frequency equipment.
The basic station is wired for and equipped with the
following equipment:
0 2-Primary R.F. Transmitters
el 2-Primary R.F. Receivers
0 2-Primary R.F. Power Supplies and Control
0 2-Duplexers
In addition, the assembly will accommodate op-
tional items A through E. These options may be sup-
plied at the time of initial installation or at any time
thereafter since the basic stations are wired to accom-
modate additional units with no changes to equipment
wiring. Inter-connection wiring can be exposed by
swinging out individual unit panels on their hinges.

EQUIPMENT ILLUSTRATED
OPTIONS
In addition to the basic equipment, various optional functions are
available to increase the utility of the system.
Ei The RF Standby Option:
Includes the necessary RF equipment to provide the basic repeater
with one standby RF combination equipment which is automatically
placed in opera-ion upon failure of either one of the primary transmitter-
receiver combinations. The standby equipment comes into operation 45
seconds after failure of the normal equipment unless the standby equip-
ments are continuously energized, in which case the transfer is accom-
plished in 20 milliseconds.
0 The Alarm Transmit Option:
Includes the necessary equipment to encode and transmit the station
identifier code and up to 6 function codes in both directions from station.
Channel 1 is assigned to this function. Normally, one of these codes is
assigned to indicate operation from auxiliary or emergency power and
another to indicate restoration of primary power. One additional code
is normally used to indicate transfer to RF standby when this option is
elected. Thus, depending on the system, 3 or 4 fault codes are un-
assigned and may be wired by the user for such items as tower light
failure, illegal building entry or any other function he chooses.

the rack are the basic units previously listed in addition
to the optional items described below.
3 The Service Channel Option:
The directional service channel option furnishes equipment to pro-
vide a service channel facility and includes the telephone instrument with
a push-to-talk switch, push-button signalling and a buzzer for indication
of incoming ringing. Channel 2 is assigned to this service. Communica-
tion and signalling is to and from one direction at a time with a switch
provided to control the desired direction of communication.
CI The Power Amplifier and Cabling Option:
Includes the necessary equipment to increase the power output of a
standard primary transmitter in the basic repeater by 6 db to 80 watts.
This option is applied only to the primary RF. Thus, when operating from
standby RF the power output is reduced by 6 db until restoration to the
primary RF is made. Mounting spaces are indicated above.
The Diversity Reception and Overlay Cabling Option:
Includes the necessary RF equipment, less antennas and transmission
line to equip the basic terminal for space diversity reception in one direc-
tion only. This option uses the Primary Receiver and an additional

DESCRIPTION
The "Carfone 150" FM Desk Station is used as the central dispatching base station to provide two-way radio
communication between a fixed location and mobile units. This equipment is available for either split or wide
channel operation. Wide channel equipment is readily converted in the field to meet split channel requirements.
The separate transmitter, receiver, and power supply are housed in an attractive dynamically styled desk cabi-
net which requires comparatively little space on a desk or table. Maintenance is facilitated by "all top tuning."
Built-in metering sockets and tuning adjustments are available by merely lifting the cabinet lid.
High quality voice transmission is assured by use of the RCA transistorized microphone which features a re-
iuctanace type voice element which works into a "hal inced feedback" transistor amplifier built into the micro-
phone case.
Remote control and multiple frequency units are optional. Equipment is shipped tuned to a specified frequency
complete with a desk microphone, ready for installation and operation.

DESCRIPTION
The Ti and T2 terminal station assemblies are typical
of the new RCA series of microwave stations which
have proved outstanding in performance and reli-
ability. Station assemblies TI and T2 incorporate the
most recent advanced developments in microwave
communications engineering, and include such fea-
tures as frequency modulation, heterodyne type opera-
tion, an output amplifier which functions as an r-f
buffer, and is designed for single sideband suppressed
carrier frequency division multiplexing. Although
these stations arc shown housed in standard 84" open
frame type racks, the same station types are also avail-
able in stylized racks with front doors and in RCA
standard 84" cabinets.
STANDARD BUILDING BLOCK UNITS
Stations are composed of standard building block
units, which are readily interchangeable with other
units of the same type, for convenient maintenance
and system versatility. Power and other inter-unit
connections are made by cables terminating in plugs,
thereby facilitating quick and easy unit changing.
Circuit components are easily accessible for speedy
circuit tracing. Stations are easily installed, tuned,
and adjusted. Once tuned, radio and channeling units
rarely need retuning. Frequency control networks in-
sure constant on-frequency operation at accuracies
within ?0.02%. Every design consideration has been
given to reliable performance and continuous unin-
terrupted service.

DESCRIPTION
The D1 assembly contains two transmitters and two
receivers for duplex radio operation. Special filter
design enables one antenna to serve both a trans-
mitter and a receiver. Moreover, antennas can be
located several hundred feet away from the source
of signals at the transmitter without the introduction
of 'frequency pulling' effects.
Convenient Channel Dropping and Insertion Het-
erodyne-repeater operation makes it possible to relay
each channel at radio frequencies without the necessity
of demodulating to the baseband. This feature results
in a minimum of audio distortion and a minimum of
variation in audio levels along the system. Channels
can be conveniently inserted and dropped without
interfering in any way with the channels passing
through.
Available Frequencies?Assemblies DI and D2 arc
available for operation at any one of the following
frequency combinations. Note that both transmitters
operate on a single frequency, and both receivers
operate on a single frequency, for greater spectrum
economy.

DESCRIPTION
The D3 assembly contains two transmitters and two
receivers for duplex radio operation. Special filter
design enables one transmitter and one receiver to
use the same antenna. Moreover, antennas can be
located several hundred feet away from the source of
signals at the transmitter without the introduction of
'frequency pulling' effects.
Convenient Channel Insertion and Dropping?Heter-
odyne-repeater operation makes it possible to relay
each channel at radio frequencies without the neces-
sity of demodulating to the baseband. This feature
results in a minimum of audio distortion and a mini-
mum of variation in audio levels along the system.
Channels can be conveniently inserted and dropped
without interfering in any way with the channels
passing through.
Available Frequencies?Assemblies D3 and D4 are
available for operation at any one of the following
combinations of transmitting and receiving frequen-
cies. POT greater spectrum economy, note that both
transmitters operate on a single frequency, and both
eceivcrs operate on a single frequency.

Approved For Release 2000/05/15 : CIA-RDP79T01049A002
DESCRIPTION
The R3 assembly contains two transmitters and two
receivers for duplex radio operation. Special filter
design enables one antenna to serve both a transmitter
and a receiver. Antennas can be located several hun-
dred feet away from the source of signals at the
transmitter without the introduction of 'frequency
pulling' effects.
All the power requirements of one rack are met
by a single heavy duty power supply. The radio equip-
ment is especially designed to be insensitive to power
variations.
Of special importance, the heterodyne repeater
method of operation used in these station assemblies
avoids the use of frequency control units at repeater
stations, as transmitter frequencies are effectively
controlled at all times by received frequencies.
Standard Building Block Units?All assemblies are
composed of standard building block units. These
Through Repeater station assemblies can be con-
verted to Drop Repeater station assemblies by the
simple addition of a Baseband Unit. Because units
are readily interchangeable, the cost of maintenance
and the stocking of spare parts is minimized.
Available Frequencies Assemblies R3 and R4 are
adjusted at the factory to operate at any one of the
frequency combinations shown in the accompanying
table. Note that both transmitters operate on the same
frequency and both receivers operate on the same
frequency. This means greater spectrum economy.

Each of these standby R-f sections is associated
with one direction of transmission. One or both
standby sections will switch in automatically, as
required, to maintain the continuity of trans-
mission at a repeater station. Also included is
a standby power supply which is energized
only if the primary power supply fails. This
assures that a properly operating power supply
is not switched-out unnecessarily.
An optional 'hot standby' arrangement can
be used to keep tube filaments of standby
equipment near operating potential. Using this
method, the switching time can be reduced to
a minimum.

DESCRIPTION
Sturdy and Lightweight ? Aluminum construction con-
tributes to the unusual lightness of these antennas. Mesh
design also keeps the weight down while reducing wind
resistance by 40 percent. Despite their light weight a sturdy
rib frame enables the antennas to withstand wind loads of
90 mph directed at an angle 45 degrees to normal.
These 'dish' type parabolas concentrate the transmitted
microwave energy into highly directive beams. When used
for receiving purposes, all the available energy is concen-
trated toward the dipole for maximum system gain and
better reception. The precision workmanship of the an-
tennas contributes to a low VSWR of 1.5/1 maximum, and
low side lobe radiation characteristics.
Easily Installed ? Antennas are designed in accordance
with RCA specifications based upon years of field experi-
ence. Lightweight construction contributes to easy installa-
tion. One man at the top of a tower can easily align the
4 foot, 6 foot or I() foot models. The dipole, designed as a
separate assembly, is easily accessible from the rear for
convenient installation and orientation. A standard 7A."
RETMA flange fitting with bleeder port connects the dipole
directly to the transmission line.
Exclusive "Gas-Block" Feature?All the parabolic reflector
antennas in this series feature a Teflon insulator 'gas-block'
with double "0"-ring seal which weather seals the trans-
mission line at the dipole. The transmission line is thus
permanently protected from the effects of rain and humid-
ity at all temperatures while the use of a dipole covering
is avoided.
Conveniently Mounted?The mesh type antenna easily
mounts on wall mounting bracket MI-31041-W, which can
be installed on standard guyed towers. When desirable,
these antennas can also
be installed on standard
pipe mounting brackets
M1-3 104 I -A.
Back of Antenna showing ac-
cessory wall mount bracket.
To install, two mounting holes
are slipped over the mounting
bolts projecting from the ac-
cessory mounting bracket. It is
then only necessary to install
the dipole, orient the antenna,
and clamp the bracing rods.

DESCRIPTION
The RCA Model CP-I28 ground plane antenna is designed to provide uniform coverage from a VHF base station. The
antenna consists of a 1/4 wave folded vertical radiator with ground plane elements spaced al- intervals of 90". The
entire unit is ruggedly constructed and will withstand the most severe weather conditions. Due to the unique design of
the antenna, the entire assembly is at ground potential, thus providing safe lightning protection. This also provides an
excellent static drain, which is extremely important when the antenna is used for receiving purposes.

USES
Designed for use with RCA Type MM-I and

with other equipment operating in the frequency
range 132 - 174 MC where stability and rugged-
ness is required for all-weather operation of essen-
tial communications service.
DESCRIPTION
Type 6061T6 aluminum alloy was selected for this
antenna because of its high tensile strength, light
weight and weldability. The Yagi elements are
heavy wall 1/2" tubing with sleeve telescoping sec-
tion of 5A" aluminum. A teflon cable inside the
folded dipole tubing acts as a matching section and
the connection for the antenna feed. There are no
wires, cables or screw terminals open to the
weather and external baluns are not required with
this unique design. Gas-expanded foam plastic is
used inside the antenna feed system to prevent the
accumulation of water. Stainless steel hardware is
used to fasten the Yagi to the screen framework.
ELECTRICAL DESIGN: The screen type Yagi has
electrical advantages over a conventional Yagi,
since a perfect screen reflector produces a gain of
6 db, whereas, a reflector for a 5 element Yagi can
contribute only 1 db to the overall gain. The
screen Yagi has a front to back ratio many times
that of a conventional Yagi. Antennas can be
mounted for either horizontal or vertical polariza-
tion, increased isolation is realized between adja-

MI-22680 SINGLE TYPE SY-41-A
STACKING ANTENNAS FOR INCREASED
GAIN: Two type SY-41B antennas with 80" x 80"
screen can be mounted vertically one above the
other for increased gain. The measured perform-
ance for this system is given in the tables on
reverse side of this sheet. A gain of 13.5 cib over
a half-wave dipole is obtained with this arrange-
ment, extremely high for antennas in the frequency
range of I 50 MC.
MOUNTING
The mounting kit SY-41-M consists of a tower
mounting bracket all the parts necessary to fasten
either one 40" x 80" screen (SY-41-A) or one
80" x 80" screen (5Y -41-B) to a tower. The mount-
ing kit is not supplied as part of the antenna and
