Description
Replacement Antenna for the EXPLORER 710
This antenna module replaces the detachable antenna supplied with the Cobham EXPLORER 710. It contains both the BGAN satellite antenna and the GNSS receiver used by the terminal for positioning and satellite acquisition.
It is a dedicated EXPLORER 710 component and does not operate as a standalone satellite terminal.
Attached or Separated Operation
The antenna can be connected directly to the EXPLORER 710 transceiver for compact portable use. It can also be detached and connected through a compatible TNC antenna cable, making it easier to position the antenna without moving the transceiver or connected equipment.
This arrangement is useful for temporary offices, broadcasting locations, field camps, shelters, and other installations where the best satellite view is separate from the main work area.
Directional BGAN Connection
The manually adjustable directional patch array must be pointed toward the serving Inmarsat satellite. It supports the Inmarsat I-4 frequency bands and extended L-band operation within applicable Alphasat coverage. Right-hand circular polarization is used for both transmission and reception.
The antenna should be installed with an unobstructed view toward the satellite and kept at least 1 meter from people during transmission.
Outdoor Environmental Protection
The antenna module carries an IP66 water- and dust-protection rating, allowing it to be positioned outdoors while the EXPLORER 710 transceiver remains protected indoors. Connections and cable routing must still be properly secured for the installation.
Cable and Terminal Requirements
A compatible EXPLORER 710 transceiver, BGAN SIM and service plan, and antenna cable are required for operation. The transceiver uses a female TNC antenna interface, and available EXPLORER 710 cable options allow the antenna to be positioned at different distances from the terminal.
