I knew that answer 20 years ago Mike. Perhaps someone has a large Slinky,
can count the turns and then give it back to his grandson (-:
Using your idea I wonder if a pair could be wound bifilar and used as
switched bidirectional?

If I every put up a Slinky-style Beverage, I'm probably going to try #12 TW
solid insulated copper wire. Probably will close-wind it on a ~4" diameter
fixture made from PVC pipe, and then stretch it out along its rope support.
Any ballpark idea what the pitch should be?

that accounted for several new countries in the Mid East and beyond and was
quite directional due to the high velocity factor making it appear to be
much longer. It is not an antenna for high conductivity soils but fine for
my granite ledge just below the surface. The steel coils also rusted away
after 18 months and after 3 replacements I quit using; painting would have
helped Im sure.
