The SOMA-800D SATCOM on the move antenna is a popular selection of Ku band antenna for emergency mobile broadband satellite communication. It is a low profile antenna with great performance in receiving and transmitting signals. The system adopts a fiber optic gyro inertial navigation tracking and satellite beacon tracking system. This SOTM antenna system features reacquisition time less than two seconds when the signal is lost.
