The Sverdlovsk High-Frequency Broadcast/Broadcast-Relay Station,
covered by photography of (see Figure leis located at 56-55N
60-41E, 5 nautical miles north-
northeast of Sverdlovsk,. USSR (see
Figure 2). The station is situated
on nearly level terrain, approxi-
mately 900 feet above sea level. It
includes a fenced operations area,
a housing and administration area,
and a maintenance and storage area
(see Figure 3). All facilities appear
to be in the final construction phase.
A 25-foot-wide paved road serves
the station and connects with the
road net in the Sverdlovsk urban
area.
The operations area is roughly rectangular and covers approximately
436 acres c7,600 by 2,500 feet). Security provisions include a perimeter
fence with eight guard towers and a gatehouse at the entrance. An internal
fence restricts station personnel to the road and operational structures.
The area contains 40 curtain antennas supported by 42 self-supporting
lattice towers, 5 rhombic receiving antennas, 2 transmitter buildings, and
la support-type structures.

The 4Q curtain antennas are divided into two groups, designated East
Group and \\''est Group. East Group contains 16 curtain antennas of uni-
form height, 'width, and number of feeds (Figure 3, items a through p).
West Group contains 24 curtain antennas of varying height, width, and
number of feeds (items as through xx). All curtain antennas are similar
to types described in a Russian publication GOST 88@5-58, Group E93,
titled Transmitting Short-Wave Synphase Horizontal Wide-Band Antennas,
Moscow, 19 8.
All the curtain antenna feed lines are buried. The southernmost
transmitter building (item A) feeds antennas a through h in East Group
and antennas as through 11 in West Group. The other transmitter building
(item Q) f ds antennas i through pin East Group and antennas mm through
xx in West Group. The feed lines vary in length from 270 to 780 meters,
with an IN,
age length of 460 meters (see Table 1).

between the two curtain antenna groups and are connected by a service
road. Each building has a modified T-shaped appearance, measures 240
by 75 feet (see Table 6), and provides 18000 square feet of covered floor
space. Each building has a flat roof with a flat-roofed monitor.(10 feet
high and 30 feet wide), probably for ventilation and light. Also located on
the roof are two vents, each 5 feet square. Two cooling ponds, one trans-
former building,
operational support building are adjacent to
Ten buildings are located along the 'service road between the trans-
mitter buildings. Three of these buildings are for operational support,
3 are for storage, one is for personnel support, 2 are for construction
support, and one is under construction. Two other buildings (items S and.
U) are water pump houses.
Utilities for the operations area include external power and internal
water. Two overhead power lines lead into the southern section of the

HOUSING AND ADMIN4NTRATION AREA

I
The housing and administration area is east of the operations area
on the south side of the entrance road.. This area contains 10 major struc-
tures of which 3 are family-type quarters, 3 are barracks-type quarters,
2 are bathhouses, and 2 are administrative-type buildings. The family-
type quarters have 2'8,500 square feet of floor space. The. barracks-type
quarters have 21,000 square feet of floor space.
The maintenance and storage area is east of the operations area on
the north side of the entrance road. This area contains 29 major struc-
tures, 2 motor pools, and 4 open-storage sites. The total covered floor
space in the area is approximately 94,000 square feet.
CONCLUSIONS
At the time of photography, the Sverdlovsk Broadcast/Broadcast-1'N elay 25X1 D
Station appeared to be (lin the final or nearly complete construction phase
and may have been pa\tially operational,
This station will probably broadcast programs which
originate here along with programs which originate elsewhere.
