• Right hand Circular Polarization
The 20-30-07 series are right hand circularly polarized directional antennas. Two plug-in extensions are supplied with the 20-30-07 to provide an increase in gain to 11 dBiC.
The antenna can easily be adjusted in azimuth and elevation for best performance and locked in position with a single thumbscrew. The tripod legs can be removed by a single thumbscrew to enable the antennas to be used as hand-held units. They are compatible with all popular military SATCOM radios operating in the UHF band.
These antennas are members of a family of quickly deployed lightweight antennas developed by Cooper Antennas Ltd for tactical military communications. Rugged design ensures reliability in arctic, jungle or equatorial desert environments. The unique Cooper Antennas design enables a single person to set up the antennas in 30 seconds, under the most demanding combat
conditions. They are especially well suited to special mission applications.
