The U.S. Navy used them for transmitting from ships in the 50's........hung

I recently read somewhere where, and please don't laugh, someone actually
used a metal slinky toy as an antenna in just your situation. He said
that
he simply let it drop out a window for DX'ing and when he was done, just
pulled it back in.

I've never heard of how successful it was, but it may be cheap and fun way
to experiment.
