six antennas of an unusual configuration at broad -
cast/communications facilities near Taldom
and Nikolayev (Figure 1). This report contains
a general description of each facility and a
detailed consideration of the antennas in which
various aspects of their physical arrangement,
engineering design, and probable correspondents
are discussed, together with some comment on
the methodology utilized in developing this in-
formation. The layout of each antenna's compo-
nents is shown graphically on the appropriate
figure for each facility; dimensions have been
collected in Table 1 for purposes of comparison.
Age of Facilities and Antennas
Although only recently noted, the antennas
are not new, their detection at this time being
largely a result of the steadily improving quality
of =IP hotography, a development that not only
makes possible the present detailed analysis of
the antennas

Comparison of Facilities
The two facilities have certain similarities,
particularly the unusually configured antennas
of which the larger and more complex Taldom
facility has four and the smaller Nikoleyev
facility only two. Other, less important simi-
larities existing between the two facilities in-
clude both being fenced and both having rhombic
high-frequency (IIF) communications antennas
arranged for the most part in day-night pairs.
Differences occur in that at Taldom the
rhombic antennas are apparently older and are
within the fenced limits of the facility, while at
Nikolayev the rhombic antennas are still under
construction and are outside the fenced limits

of the facility. Other items not found at both
facilities include several curtain arrays noted
only at Nikolayev and two tower-mounted re-
flectors observed only at Taldom.
final noteworthy similarity between the
facilities is that both also contain in addition to
so-called standard control buildings- -cleanly
designed, rectangular structures with adjacent
cooling ponds/tanks--other probable control
buildings of a distinctly unique appearance.

The Taldom broadcast/communications fa-
cility is situated at 56-
44-25N 37-36-00E, an area of slight relief 2.3
nautical miles (nm) east-northeast of the center
of the town of Taldom (Figure 2). The approxi-

reasonably heavy vegetation covering a major
portion of its fenced area (Figure 3). Elec-

antenna (there is also a seventh, seemingly extra
building at I'aldom for which no corresponding
antenna can be located), consist of a relatively
small, generally rectangular end structure with
from two to four long, narrow wings or linear
cells, lower than the end structure and most often
attached to and perpendicular to it, but in some
cases apparently not connected, and in one
instance placed at an angle. (A perspective
view of one of these probable control buildings
appears at the foot of the single tower in
Figure 9.)
tronic components in the operations area of the
facility (Figure 4) include 4 of the previously
mentioned antennas of unusual configuration,
11 IIF rhombic antennas, 2 antenna reflectors
with probable feed towers, a probable vertical
:radiator antenna tower with a probable ground
system, and at least 6 other unidentified towers.
The four unusually configured antennas are
discussed in detail in a separate section of this
report, below; their dimensions are given in

ground level. One hundred and five feet north
of the eastern antenna reflector is a 70-foot-
high probable feed tower; in all likelihood a
similar tower is situated in front of the western
reflector, but ground shadows preclude its
observation. Centered just north of the probable
feed towers is a small control building with an
adjacent cooling pond/tank.
Other standard-type control buildings, in
addition to the one just mentioned, include at
least one other small and three larger ones,
the latter all having adjacent cooling ponds/
tanks. There are also five of the probable
control buildings of unique appearance which
have been described previously.
A small support area is situated in the ex-
treme southern part of the facility, adjacent to
the village of Yurkino.

area include two curtain arrays (one 3-bay and
one 2-hay), and a probable vertical radiator.
Under construction outside the fence are 10
double rhombic antennas, 8 of which are arranged
as 4 day-night pairs. The azimuths shown for
these antennas on Figure 8 are only approximate.
Control buildings in the area include 3 of the
standard I-IF type, each having 2 adjacent cooling
ponds/tanks, and 2 of the previously described
probable control buildings of unique appearance,
one associated with each unusually configured
antenna. In the northwestern corner of the area
is a large reservoir with several adjacent sup-
port buildings, and a few other support/control
buildings are found throughout the area.
The support area, adjoining the northern
limit of the operations area, contains over 20
barracks-type, administration, and general-
purpose buildings.

150 feet. The facility (Figures 7 and 8) con-
sists of separately fenced operations and sup-
port areas, with a number of rhombic antennas
under construction to the south and west of the
operations area fence.
The operations area includes two of the
unusually configured antennas, one large and
one small, which appear virtually identical in
design to those at Taldom. llowever, the larger
antenna has two fixed self-supporting feed
towers, and the smaller antenna has its single
feed tower mounted on a two-rail track which
is somewhat wider than--although otherwise
similar to--the three comparable tracks at

General Description 25X1 D
Basically, the antennas consist of either 9
or 13 guyed towers arranged in a slight are
that faces a self-supporting feed tower which is
either fixed or mounted on a low gantry-like
structure on a two-rail track laid out parallel
to a line drawn between the end towers of the
