1.
VHF/UHF SATCOM ANTENNA, MODEL ADM-C2
Model ADM-C2 is a quick setup, less
than 3 minutes and easy to store, transportable, light weight crossed
Yagi satellite communication (SATCOM) antenna designed for the frequency
range from 240 to 318 MHz. The antenna is right hand circularly
polarized with an axial ratio of less than 3 dB at 3dB beamwidth
points. The antenna produces a horizontal beam width of 6 to 26 degrees
at - 3 dB points and 11 to 46 degrees at 10dB points with sidelobe
suppression of greater than 12 dB. ADM-C2 has a minimum power gain of 10
dBi at 244 MHz and 14 dBi at 318 MHz and is capable of handling 200
Watts of Cw power. The SWR of the antenna less than 1.5:1.0 over the
frequency range with a nominal impedance of 50 Ohms.
ADM-C2 mounts on a tripod with
adjustable leg length. The antenna can be positioned in azimuth over 360
degrees and elevation can be adjusted over 0 to 90 degrees in 10 degree
increments. Tripod legs support a ballast on which a radio or sand bag
can be placed.

HIGH GAIN SATCOM HELICAL ANTENNA, MODEL ADM-C5
ADM Corporations Helical Antenna
has been designed to meet the requirements for a fully militarized high
gain base station SATCOM Antenna.
Model ADM-C5 is a Right Hand
Circularly polarized helical antenna of very rugged construction,
designed to operate under the most difficult operating conditions of
high wind, ice or snow. The helical antennas are built to withstand wind
speeds to 60 knots while coated with two inches ice.
The aluminum antenna mast Model
MAST-C5 (optional) can be used to set antenna elevation from the
horizontal to the vertical, and azimuth may be adjusted through 360
degrees.

GROUND/SHIPBOARD/MOBILE SATCOM ANTENNA, MODELL ADM-
C25/HM
Model ADM-C25/HM antenna is a low
silhouette/profile hatch/ground/shipboard/mobile SATELLITE COMMUNICATION
(SATCOM) ANTENNA designed for the frequency range from 225 to 400 MHz.
The antenna is right hand circularly polarized and produces
hemispherical (broadbeam) radiation pattern in the upper half of the
sphere. The antenna has a nominal power gain of +3dBic and it is capable
of handling 200 watts of Cw power. The SWR of the antenna is less than
1.5: 1.0 with a nominal impedance of 50 Ohms.
The antenna is protected from damage
and environment by a dome shaped fiberglass radome.

VHF/UHF SATCOM MANPACK ANTENNA, MODEL ADM-C8A
Model ADM-C8A is a quick setup, easy
to store, and easily transportable, lightweight VHF/UHF SATELLITE
COMMUNICATION MANPACK ANTENNA designed for the frequency range from 240
to 400 MHz. The antenna is RHC polarized with an axial ratio of less
than 3 dB. The antenna produces unidirectional radiation pattern with a
nominal power gain of 7 dBic, and with two extensions for a total of six
director elements a power gain of 11 dBic. The SWR of the antenna is
