677-A0205 Cobham Aviator LGA-3000 Low Gain Antenna
677-A0205 Cobham Aviator LGA-3000 Low Gain Antenna, Aeronautical
The LGA-3000 is a fuselage mount omni- directional antenna, designed to enable access to Inmarsat SB200 services.
A unique feature of this product is the integrated GPS antenna that enables the Cobham AVIATOR 200 range of solutions to operate
as stand-alone systems, without inputs from aircraft navigation or the installation and connection of a third party GPS antenna.
This makes the Cobham AVIATOR 200 systems the most compact solutions for the provision of reliable and affordable voice and data connectivity, and extends SwiftBroadband connectivity options right down to the smallest of manned and unmanned airframes.
General Description
The LGA-3000 is a Low Gain Blade Antenna with integral Global Positioning System (GPS) Antenna
functionality, forming one component of an Inmarsat SB200 Class 15 SwiftBroadband solution. The antenna
complies with the relevant Inmarsat standards.
Equipment Description
The LGA-3000 Low Gain Antenna (PN: 677-A0205) is a non-steered antenna taking the form of a typical
aeronautical blade. It includes a GPS Patch for the position reporting required by Inmarsat’s network (for
operational reasons), making it the only antenna capable of supporting a self-contained 3 LRU SB200
solution.
The main features of the antenna are:
1. Inmarsat approved for SB200;
2. Designed specifically for Inmarsat’s SB200 Service and its relevant system architecture;
3. Extended L-Band compliant;
4. Built-in GPS Antenna and LNA;
5. Weight of less than 630 grams or 1.38 lbs.
