    The MIL Series brings a new level of digital performance and reliability to video and audio transmission. Available in P, L, S, and C–Bands, the MIL Series provides a minimum of 200mW to deliver highly reliable link performance. Utilizing COFDM modulation coding, the MIL Series provides superior multipath performance compared to traditional analog video transmission.

    As a result of COFDM, stable imagery is obtainable over a wide range of operational conditions. Image quality is excellent due to high-quality low-latency MPEG-2 video compression and advanced forward error correction algorithms. The MIL Series is designed for long range non-line-of-sight video collection activities. A user selectable AES encryption key safeguards against unauthorized interception.

    Packaged in rugged aluminum housing, the MIL Series is engineered for applications where severe environmental conditions are the norm. Frequency selection, COFDM mode, and encryption keys are controlled through a multifunction front panel user interface. A comprehensive front panel 25-pin connector provides quick and easy integration into any system without expensive specialized connectors. Transmission parameters may be programmed into the unit through the built-in LAN interface.

    The MIL Series transmitter is well suited for applications in Homeland Security, surveillance, law enforcement, military UAV, UGV, RPV and MOUT, as well as airborne data/telemetry.
