Hughes 9450-C11 BGAN Satellite Antenna (Magnetic Mounts Not Included)

Automatic On-the-Move Tracking

The C11 is a fully autonomous tracking antenna designed for land-mobile BGAN communications. Once connected to a compatible Hughes 9450 terminal, it automatically acquires and tracks the Inmarsat satellite while the vehicle is moving. This allows the connected system to support shared IP data rates up to 464 kbps and streaming IP service up to 128 kbps, depending on the terminal, service plan, and network conditions.

Compact Vehicle Installation

With a diameter of 25.2 cm and a height of 11.9 cm, the C11 has a low-profile design suited to vehicle roofs where installation space is limited. It can be permanently mounted using the integrated mounting holes or paired with the separately available three-piece C11 magnetic mounting set for removable installations on compatible steel roofs.

The antenna should be installed horizontally with a clear view of the sky. Hughes recommends maintaining a minimum safe distance of 1 m to the side of and above the antenna during operation.

Single RF Connection

The antenna uses a 50-ohm female TNC port that carries L-band RF signals, antenna-control signaling, and 42V DC power from the Hughes 9450 Indoor Unit. A compatible 50-ohm coaxial RF cable with TNC connectors is required between the antenna and modem.

Because the RF cable also supplies DC power, the Hughes terminal must be switched off before the cable is connected or disconnected.

Outdoor Operating Protection

The antenna housing is rated IP56 for protection against dust and water exposure. It operates from -25°C to 55°C and can withstand survival temperatures from -40°C to 80°C. The permanently mounted antenna is rated for wind speeds up to 125 mph, while an installation using the optional magnetic mounts is limited to 100 mph.
