pharosantenna Edit

http://diydrones.com/profiles/blogs/cool-pixhawk-compatible-long-distance-directional-radio Pharos matches a dynamic directional (beam shaping) radio on the air with another on the ground, with the two tracking each other for multi-mile range for video and telemetry. Coming to Kickstarter in 2-3 weeks. The Pharos is a newly-developed smart antenna. Unlike conventional omni-directional antennas that waste energy in all directions, the Pharos concentrates the available power where you need it most. Working in conjunction with the Pixhawk autopilot (a version with its own autopilot is being also developed), the antenna activates the side facing your UAV, boosting reception and range. A second Pharos can also be used on the aircraft, quadrocopter or UAV, keeping ground control in aim at all times. The Pharos is also circular-polarized, granting immunity to polarization losses and multipathing signals, an optimum choice for challenging environments.

2.4ghz video units Edit

From 50mW to 1Watt

www.jasco.co.za Edit

http://www.jasco.co.za have electronic engineers that can develop radio systems on any frequency. They did systems on 1Ghz for the mines(illegally) in South-Africa, a frequency used for missile tracking in the northern hemisphere. 1Ghz will give better LOS throughput that 2.4ghz or 1.2ghz and cut down on spectrum pollution in the ISM bands.
