Modern acrobatic kites use two or four lines to allow fine curb of the kite's angle to the wind. Traction kites may have an additional line to de-power the kite and quick-release mechanisms to disengage flyer and kite in an emergency.

Kites can be absorbed for radio purposes, by kites carrying antennas for MF, LF or VLF-transmitters. This method was fanatic for the reception station of the first transatlantic transmission by Marconi. Captive balloons may be enhanced convenient for such experiments, because kite carried antennas require a lot of wind, which may be not always possible with cumbrous equipment and a ground conductor. It must be taken into account during experiments, that a conductor carried by a kite can ahead to a high voltage toward ground, which can endanger people and equipment, if http://www.pictureprettykites.com suitable precautions (grounding through resistors or a parallel resonant-circuit tuned to transmission frequency) are not taken.
