An improved mobile satellite communication system comprises an antenna configured to transmit and receive signals from a satellite and a modem connected to a mast to generate a wireless WiFi zone around the system to allow persons within the zone to access the Internet and communicate via wireless telephones and fax machines. The system comprises a lightweight, relatively small sized trailer having electronic cases containing the necessary electronics and storage cabinets containing other equipment and materials. Front and rear stabilizing mechanisms extend outward from the trailer to stabilize the system when in use. A collapsible or foldable tow bar is provided for transporting the system with a vehicle. The antenna is mounted on a support structure above the electronic cases and supported by the cabinets. Preferably, the satellite system is sized and configured to be transported by conventional, smaller sized helicopters and to be relatively inexpensive to manufacture.
