Many applications require a single box solution, easy-to-use and containing everything needed for high-power
transmission. EB downlink solution includes, within a rugged briefcase the MPEG2 audio/video encoder, the COFDM modulator and an high-power amplifier.ESAD Airborne Downlink System
AIRBORNE DENG SYSTEMY
The unit provides everything required in an ultra compact case for use
into helicopters and fixed wings aircrafts.
The downlink unit can be powered by a 12Vcc battery pack or by 28Vcc
of the helicopter or aircraft.
A separate control panel is available as optional unit.
Standard transmission frequency range is 2.5 – 2.7 GHz.
Other frequency ranges are available on request.
Output power: 1W – 5W switchable.
TX antenna: linear omni-directional with 360° constant azimuth
coverage, housed in a self-contained fiberglass radome, weather resistant – low profile.
Helicopter option: electro-mechanical actuator mount.
Ground DENG system The reception of the downlinked signals can be achieved by different antenna systems: •
Omni-directional antenna with 360° constant azimuth coverage, housed in a self-contained fiberglass
radome, weather resistant – low profile. •
Directional antenna •
Array of four directional sector antenna housed in a fiberglass radome with 4 ways diversity receiver •
Array of eight directional sector antenna housed in a fiberglass radome with 8 ways diversity receiver The choice of the proper antenna receiving system depends on the area coverage needs. Furthermore it is very important to know if you have or not line-of-sight, in respect of the transmitted signal. The choice of a diversity receiver system Applications • • • • • Features • • • • •
