KAE, also known as Projekt 62630-66 was a ground
antenna for HF
radio signals, developed around 1985 in the former DDR (East-Germany).
The antenna consists of a number of interconnected wires that can be burried
into the ground, whilst still being able to function as an antenna.
The antenna is fully invisible for air reconnaissance and was frequently
used with Cold War bunkers in the DDR.
The KAE was also used with the WSA-1 and WSA-6 spy radio sets.
