the antenna weighs 2500 pounds and is 15 feet high,
10 feet wide, and 10 feet deep. The gain characteris-
tics of this antenna are nominally 15 dB in transmit
and 18 dB in receive.
ANDREW 58622 SHORE ANTENNA
The Andrew 58622 antenna (fig. 2-33) is a bifilar,
16-turn helical antenna right-hand circularly polarized,
with gain varying between 11.2 and 13.2 dB in the
240-315 MKz frequency band. It has a 39-inch ground
plate and is about 9 feet, 7 inches long. It can be
adjusted manually in azimuth and elevation. This
antenna is used at various shore installations, other
than NCTAMS, for transmit and receive operations.
AN/WSC-6(V) SHF SATCOM
The antennas used on current shf SATCOM
shipboard terminals are parabolic reflectors with
casseegrain feeds. These antennas provide for LPI (low
probability of intercept), with beamwidths less than
2.5 degrees (fig. 2-34). The reflectors are mounted
on three-axis pedestals and provide autotracking of
a beacon or communication signal by conical scanning

techniques. The antennas are radome enclosed and
include various electronic components. Both a 7-foot
model (fig. 2-35) and a 4-foot model (fig. 2-36) are
operational in the fleet.
