Detailed analysis of the six international
radio communication/broadcast stations de-
tected on photographic coverage of Cuba through

bility with Moscow, with nearly all of the capital
cities of Central and South America, with many
of the capital cities of Central -Europe, and
probably with certain countries of Central
Africa.
This study, made possible through the larger
0
scale and greater detail of recent photography,
presents precise data on the six presently known
international radio stations in Cuba, including
several previously unreported locations. All
six are in the general area of Havana (Figure
1 and Table 1). A subsequent report is expected
to cover internal Cuban communication facili-
ties. -
Utilizing the more comprehensive photo-
graphic coverage now available, not only can the
approximate frequency range be estimated,** but
it is also possible to align the antennas with
such accuracy that in most cases the probable
correspondent can be determined. Thus, of
the majority of the 73 long-range antennas de-
tected, the great circle projection of their orien-
tation azimuth passes through a single capital
city. Further, certain capitals, such as Moscow,
are intersected by more than one antenna orien-

tation azimuth projection from more than one
station. Therefore, it would appear-that with
few exceptions the stations operate on a point-
to-point rather than general broadcast basis.
The information produced by this study is
presented in graphical and tabular form. For
each of the six stations reported on, there is 1)
an annotated photograph (Figures 2 through 7);
2) a table of measurements and other data (Tables
2 through 7); and 3) a world map showing the
probable correspondent of each antenna (Figures
8 through 13).
Generally, no distinction is made between
those antennas used for radio communication and
those used for radio broadcasting, as this func-
tion is not determinable from aerial photography,
the sole source utilized in the preparation of this
report. However, detailed examination did de-
termine the design of the antennas to be such
that they could be adapted to perform either
function on the point-to-point basis mentioned
above.
In addition, unless there is no doubt as to an
antenna's directivity, the tables show both the
forward and back (180 degree opposite) orienta-

tion azimuths. This is necessary with many re-
ceiving rhombic antennas, for example, since
there is no dissipation line and propagation could
be off either end of the antenna. In such cases,
no attempt was made through collateral intelli-
gence to determine the actual correspondent, but
the most likely entered in the forward projection
column as determined from photographic evi-
dence alone. Thus, if an antenna is beamed in
one direction through a field of other antennas,
while the opposite end has a clear "field of fire,"
then the clear end will be shown as the forward
projection entry unless some further considera-
tion takes precedence.
