Back in the WW II years,some of the Swiss people used transmitters and
to get the antennas up high enough in the air because of the mountains
they used some big baloons filled with hydrogen or helium gas and the
antenna wire was which was attatched to a baloon and the other end of
the long wire was attatched to a home made reel which was usually made
of wood,sort of like a big fishing reel.When they was through
transmitting untill next time,they would use the reel to haul down the
antenna.I read about that in a Saga magazine way back in the 1950's.
