If the aircraft/UAV is large enough it is not be an issue generally. The restricting factors are power and weight sufficient to give you realtime broadband rates in X-Band or even Ku-Band. Antenna size is an issue if the platform is too small. The solution as I mentioned is a well established UAU for local use and then the big expensive one for long range stand off. Something the size of the DA42 or similar size already has to power cameras, recorders then the transmission gear. Its probably at best very very close to the limits. Its best to remove the pilot as they are a waste of valueable real estate plus also a liability if they come down on the wrong side of the line. Hence in answer the Israeli type UAV is good for the tactic solution and leave the long range big ones to those countries who can afford them.
