I suggested this about two years ago as a DXpedition antenna for 160m.
With the right drone, it could hold up enough wire to continuously power
it, and with GPS it would automatically adjust for varying wind. It's
not a backpacking antenna, though ... far too much weight.

Then there is the possibility of having synchronised pairs of drones suspending a multi element Yagi, which can be rotated, height varied to suit desired desired take off angle, element lengths reeled in and out to change bands. <patent pending>
