The DM C101-3 Ground-Based Satellite Communication Antenna (Military Nomenclature AS-3438/G)
is a high-gain directive crossed dipole array. The unit is for ground-based deployment where a higher
antenna gain for more secure communications or high data rate transmission is required. When used
in conjunction with masts, the DM C101-3 may be taken from a stored configuration and be fully
deployed in less than five minutes.
The DM C101-3 is compatible with the DM AB-1 or DM EM4-1 antenna masts, both of which can be
mounted to shelters for manual directional (azimuth and elevation) steering. Optional accessories
such as the DM U112-Series and DM U131-Series permit fixed site installations on customer provided
masts.
The DM C101-3 is extremely rugged and withstands difficult environments including the MSC-64
system requirements.
