Airborne Downlink

In 30 years of business, BMS has earned the title “The Downlink Experts”
Our fourth-generation COFDM digital downlink system, powered by the flagship Heli-Coder 4 transmitter, represents the culmination of over 10 years of work, customer input, and BMS innovation in the digital downlink market. The Heli-Coder 4 incorporates MPEG-4/H.264 compression, uni-directional Ethernet input, and decreased power consumption into one box.

Great things come in small packages, and the Heli-Coder 4 is no exception. With a transmitter weight of 6 lbs. and a total system weight of approximately 8 lbs. (not including optional TAA-101 Antenna Actuator), the Heli-Coder 4 weighs less than 50% of the Heli-Coder II and exactly half of the weight of the Heli-Coder III. This reduction in weight is accompanied by an 80% reduction in volume over the Heli-Coder II, and a 50% reduction in volume over the Heli-Coder III.
