Bayed ?70cms? yagis with an altitude-azimuth
rotator. The yagis look to be 20 or so elements.
The rotator can swing the antennas around 360
degrees but also tilt it up and down so it can
aim anywhere in the sky. Two antennas are used
to get an extra ~3dB gain, double the signal.
Very high gain, but narrow beamwidth so the aiming
software has to be good to track the 'bird'.
Looks like some kind of portable mast being used
as support.
