Hey Bob thanks for posting that
The antenna he's using doesn't look all that flash but I like the tracker
The APM flight controller can be used as an antenna tracker controller.
It wouldn't be that expencive to make up
One of the issues with an antenna controller that relies on GPS is that if the GPS signal fails for some reason then you've lost tracking. At least with a diversity system as long as you have a video signal it will choose the best antenna.
There are antenna trackers that work on RSSI (received signal strength indicator) to track the signal. This is pretty easy to set up if you have two recievers and two antennas and only track in one plane.
I've often thought about making an antenna tracker but the amount of work and complexity involved was out weighed by the simplicity of a diversity system. Antenna trackers are very cool things and probably a better option if you had a really high gain directional antenna and wanted to go for long distances
