Mmmm. Kite antennas are for summer ;-)


What? Ehm, no. They are for winter! :-)
See: http://www.iup.uni-heidelberg.de/schaefer_vlf/VLF/300m%20VLF%20kite%20vertical.jpg

Helium is much to expensive and you can use the baloon just one time, then you have to release the gas again. This is not practical! And if there is strong wind, the baloon is not very stable, expect you make it much larger than necessary, so there is a strong force on the wire.

A kite however can stay stable in the air for hours! Once i kept it in the air (including a 100m wire connected) for > 24 hours. Everyone (even if retired!) can buy a kite and some string and rise it somewhere :-)
