INTRODUCTION
The Kuybyshev High-Frequency
covered by photography of
6 nautical miles north-northeast of
Kuybyshev, USSR (see Figure 1).
The station is situated on rolling
upland etched by gullies, approxi-
mately 600 feet above sea level. It
includes a fenced operations area
and a support complex made up of
a housing and administration area,
a maintenance area, and a storage
area (see Figures 2 and 3). A 25-
foot-wide paved road serves the
station and connects with the main
Broadcast/Broadcast-Relay Station,
is located at 53-17N 50-15E,

road leading north from the Kuybyshev urban area. Operational facilities
at the station appeared to be undergoing modernization at the time of the
photography.
OPERATIONS AREA
25X1D
The operations area is roughly rectangular and covers approximately
580 acres (maximum dimensions of 6,500 by 4,900 feet). The entire area
is secured by a wire fence supported on line poles. A large
portion of the operations area (approximately 200 acres) is covered by
dense mature timber. The area contains 39 curtain antennas supported
by 43 quadrupedal lattice towers, 3 dual horizontal rhombic antennas, 2
center-fed horizontal dipole antennas, one microwave tower, 4 transmitter
buildings (one under construction), one antenna maintenance area, and a
group of construction support buildings.

The 39 curtain antennas are divided into four groups, designated
Antenna Groups A, B, C, and D The three dual horizontal rhombic an-
tennas are designated Ra, Rb, and R. The two center-fed horizontal dipole
antennas are designated Da and Db. The four transmitter buildings are
designated transmitter buildings A, B, C, and D. Because of the complex
feeding arrangements for the curtain antennas, these antennas are not
described according to their group, but according to their association with
specific transmitter buildings. In certain cases, an antenna is fed from
two transmitter buildings.
Transmitter Building A and Associated Antennas
Transmitter building A is a modern structure measuring 210 by 95
and 30 feet high. It has a longitudinal monitor and four vents on the roof.
The monitor measures 165 by 25 feet and each vent measures 15 by 10
feet. Feeders lead from the transmitter building to two outdoor multi-
position switch yards measuring 260 by 110 feet and 140 by 50 feet, res-
pectively (see Figure 4). All the curtain antennas in Antenna Group A and
antenna p in Antenna Group B are fed solely from transmitter building A.
Antennas e through j in Antenna Group B are fed from both transmitter
building A and transmitter building B. Feed-line lengths from switch yard
to antenna vary from 650 feet (antenna a, group A) to 3,250 feet (antenna p,
group B). Pertinent information concerning the antennas is given in Tables
1 and 2
Transmitter Building B and Associated Antennas
Transmitter building B is an old-type structure measuring 235 by
45 and 35 feet high. The roof supports numerous objects which appear to
be ornamental rather than functional. A buried feed line leads northwest

from the transmitter building to the main switch house measuring 60 by
20 and 20 feet high (see Figure 5).
Transmitter building B feeds all the antennas in Antenna Group B
except antenna p (located between towers 16 and 17), which is fed only
from transmitter building A. Six of the antennas in Antenna Group B
(antennas e through j) are fed jointly by transmitter buildings A and B.
The feed-line lengths from the main switch house to the antennas in
Antenna Group B vary from 800 feet (antenna k) to 2,700 feet (antenna a).
All feed lines are aboveground wire lines with the exception of a portion
of the feed to antennas 1 through n, which is buried. This buried feed line
is of recent construction and may indicate future modernization of feed
lines, since aboveground wire lines always create serious technical prob-
lems of winter maintenance. Three secondary switch houses, in addition
to the main switch house, are utilized to handle the complex feeding ar-
rangements for the antennas.
A 50-foot-high microwave tower, with two possible reflectors, is
located south of transmitter building B. Pertinent information concerning
the antennas in Antenna Group B is given in Table 2.
Transmitter Building C
Transmitter building C is similar to transmitter building A and mea-
sures 210 by 95 and 30 feet high (see Figure 5). It has a longitudinal mon-
itor and four vents on the roof. The monitor measures 165 by 25 feet and
each vent measures 15 by 10 feet. Externally, the structure appears com-
plete, but as indicated by the absence of feed lines and the rough appear-
ance of the ground surrounding the structure, the building is undergoing
internal construction or equipment installation. The closeness of this
transmitter building to transmitter building B suggests that the former
might be intended to replace the latter.

Antennas Ra Rb' and Rc are dual horizontal rhombic antennas with
optimal wave lengths in the upper limits of the high-frequency band. A
dual horizontal rhombic antenna consists of two single rhombic antennas
suspended in two horizontal planes and displaced along the small diagonal
of the rhombus, the larger diagonals of the rhombuses remaining parallel.
Antenna Ra is a bidirectional transmitting rhombic with a centrally
located transmission direction switch and an obliquely located absorbing
(dissipation) line. Antennas Rb and Rc are graphically shown in Figure 6
as transmitting and receiving, respectively. Both antennas could be for
transmitting or bidirectional transmitting, but this cannot be determined
because the photographic image in this area is poor. The apparent parallel
hookup also suggests a design to increase the coefficient of amplification.
Antennas Da and Db are high-frequency center-fed horizontal dipoles.
Antenna Da appears to be a standard doublet, while antenna Db appears to
be a delta-matched doublet.
Radiation Azimuths
The radiation azimuths shown in Figure 7 are calculated from per-
pendicular bisectors of the curtain antennas and horizontal dipoles and
along the major axes of the rhombics. These azimuths represent the
major radiation lobes, without regard to minor or secondary lobes. Both
fore and aft azimuths are shown since director-reflector characteristics
cannot be determined from the photography.
Operational Support Facilities

cooling ponds, and transmitter building C (item 3)has two nearby probable
cooling towers. Approximately 20 construction 'support structures and a
possible earth-covered water-storage tank are in the vicinity of these two
transmitter buildings. Transmitter building D (item 4) has two working
cooling ponds. All the transmitter buildings are served by a paved road,
and there are paved parking aprons in front of each building.
A fenced probable antenna maintenance area (item 5) contains ten
structures and an area for open storage. Five major structures in this
area are single-story gable-roofed buildings measuring 190 by 35 feet,
95 by 35 feet, 85 by 35 feet, 80 by 35 feet, and 60 by 35 feet, respectively.
High-voltage power (item 6) enters the eastern portion of the opera-
tions area from two separate grids to a fenced substation (item 7). The
internal power network (item 8) appears to be in the final stages of conr
version from aboveground wire lines to underground conduits. Above-
ground probable telephone lines (item 9) interconnect the transmitter
buildings
SUPPORT COMPLEX
The support complex is located adjacent to and south of the operations
area (see Figure 3). This complex consists of a housing and administra-
tion area with 30 major structures (item 10), a general maintenance area
with 6 major structures (item 11), and a general storage area with 13
major structures (item 12).
CONCLUSIONS
At the time of photography, the Kuybyshev High-Frequency Broadcast/
Broadcast-Relay Station appeared to be operational, as evidenced by the
working cooling ponds. It also appeared to be an old station undergoing
modernization, as indicated by recently constructed underground power

and underground feed lines. Another indicator of this is the possible fu-
ture replacement of transmitter building B by transmitter building C,
still under construction. This station probably broadcasts programs
which originate here as well as programs which originate elsewhere. The
