The Application of Medium Range (up to 50 miles) Video Downlinks from a Law Enforcement Helicopter

A Medium Range System has an Omni directional antenna on the aircraft and a high gain directional antenna on the receive end (ground). The aircraft can transmit to both short range receivers and medium range receive sites simultaneously. High gain antennas have narrow beam widths, and have to be pointed at the transmit site (aircraft). The pointing can be done manually, or automatically with GPS steering. GPS steered receive systems are typically located in a fixed place like a dispatch center. The Medium Range system gives coverage up to 50 miles radium from the receive antenna.
