LIU-LI-HO RADIO STATION, 'CHINA
The Liu-Ii-ho Radio Station* is located
at 39-38-18N 116-05-20E, approximately 3.0
nautical miles (nm) north-northeast of Liu-li-
ho, China (Figure 1). The station covers approx-
imately 285 acres, and contains a fenced oper-
ations area and an adjacent fenced support area
(Figure 2).
The operations area contains a domed
multistory studio/control building, 120 by 120
feet- (Item A, Figure 2); one multistory trans-
mitter building, 120 by 50 feet (Item B, Figure
2); one multistory transmitter building, 100 by
55 feet with a 90- by 45-foot wing (Item C, Fig-
ure 2); four cooling ponds, each 50 feet in diam-
eter; approximately 20 smaller buildings; and 24
self-supporting lattice towers, each bearing a
crossarm on top.
The 24 lattice towers are capable of sup-
porting up to 23 high-frequency curtain arrays.
Lack of adequate photography precludes the iden-
tification of all the transmission lines and it
cannot be determined if a curtain array is
present between each set of towers. The cross-
0
CIA/PIR-23/64
arms on the towers indicate that each curtain
array has a reflector screen and/or beam-
switching capacity. Table 1 gives the azimuths
and other mensural data for each curtain array,
with nominal design frequency for both four
bays and eight bays.
At the Hsien- yang Radio Communications
Station, China, 1/ it was assumed, based on the
number of feed points, that each curtain array
probably contained four or eight bays (one bay
equaling one-half wave length). At Liu-Ii-ho,
feed points cannot be established, but the simi-
larity between these two stations suggests that
the higher curtain arrays at Liu-Ii-ho may each
contain four bays, and those of lower height may
each contain eight. Table 2 groups the antenna
arrays by their orientation, and predicates the
number of bays for each array on the basis of
its height. Measurements in both Tables 1 and
2 are estimated to be accurate to within 10 to
15 percent.
The support area contains about 33 build-
ings, including 16 barracks, 3 administration
buildings, and 14 storage and miscellaneous
buildings.

*Curtain antenna array designators are based on the numbers on Figure 2 identifying the towers between which each
array is suspended.
**Based on total height of shortest supporting tower. Allowance has not been made for curtain sag.
***See Figure 1.
****Based on one-half wave length per bay with one-quarter wave length allowed at each end of curtain for support wires.
