ELECTRONIC INSTALLATION. FOOCHO'+K
This report was prepared in answer to a request for detailed photo
analysis of possible rhombic antenna installations located near Foochow,
China'
The tennas were located on the aerial photography of
The photos have a scale of 1:9450, and were taken wit
The location of the antennas was found to be 260 06' 15" North
latitude, 1110 18' 20" Fast longitude. Polyconic grid reference. Band
III N. Lone "D", 334583 Sheet 8833-II of AMS series L783, 1:5C.000 was
used. This map sheet was also used in the determination of the angular
orientation of the antennas,
The orientation of the antennas was found to be
orientation of both the large and the small arrays, using the long axes
as the references
The two antennae arrays are geometrically similar. as shcwn by the
arrangement of the poles. Each is symmetrical about both axes.'
The heights of the poles could be determined only approximately,
although both parallax and shadow methods were attempted. Photographs
made from copy negatives were the only ones suitable for measurement
 I
because the area on the original photos had been defaced, Because of the
poor resolution of the copy prints, precise heights could not be determined:
when other prints from the original negatives become available, better
height measurements will be made. if still desired8
The heights, distances between poles, and relative location of the poles
are shown on enclosures 1 and 2a
Aside from-the poles, only one characteristic of the installation
was noted. It is a small building. enclosed by a compoyni)-like fence,
and appears to be a part of the electronics-antenna complex.,
.The heights of the poles are
