677-A0181 Cobham Aviator IGA-5001 Intermediate Gain Antenna
677-A0181 Cobham Aviator IGA-5001 Intermediate Gain Antenna, Aeronautical
The IGA-5001 is an Intermediate Gain Antenna (IGA) that is designed for direct interfacing with the COBHAM series of Satellite Data Units (SDU’s) which contain the beam steering function.
The IGA communicates with the SDU using the COBHAM proprietary modem interface via the control port along with the 28 VDC. and the GPS RF signal. The antenna is ideally suited for use in dual Channel Class 7 SBB systems
The IGA-5001 is a fuselage mount electronically steered, phased array antenna.
It is a rugged and reliable product gaining from the field experience of the HGA-7000 and HGA-7001, the latter being the antenna
of choice on new air transport aircraft.
It is fully compliant with the Inmarsat SDM and is considered to be the optimum antenna solution for Inmarsat’s SwiftBroadband
Class 7 service.
It is by far the smallest Intermediate Gain Antenna certified for both single and multi-channel operation.
Features
- Low profile
- Small footprint
- Solid state highly reliable design
- Integrated GPS antenna
- TSO-C132 certified
- Fuselage mount with simple connection via two TNC Bulkhead feedthroughs
- Over 60% smaller and 34% lighter than its nearest competitor
Partnered with Cobham’s AVIATOR range, it makes a compelling case for moving Inmarsat voice and data services onto
smaller aircraft types.
