Activating the Cobham SAILOR 900 Ku VSAT system involves securing the antenna, connecting it to the modem, and configuring the settings for the network. Ensure the antenna is mounted in a location with clear access to the satellite. Connect the modem to the antenna and input the activation settings provided by your VSAT provider. Once activation is complete, test the system’s functionality to verify that internet connectivity is stable. For any issues during activation, such as poor signal strength or modem errors, contact Cobham support for troubleshooting or professional installation assistance.
