Hi Jim,
As we move the turns closer, we increase the velocity factor too much. At
some point, the Slinky will receive off the opposite (feed) end. Tom
explains it at
www.w8ji.com/slinky_and_loaded_beverages.htm .
And I just found this, where K5UO seems to say that his Slinky was about 12
turns pe
the rope, past the point where it fires backwards (and
then some), maybe.
Using your idea I wonder if a pair could be wound bifilar and used as

The best thing I ever did for Topband receiving was to lay out a 220 foot wire
on the ground pointed NE to Europe. I then put one down for 480 feet due West.
Switching from one to the other was dramatic. Because I could just hear
stations to the south but not copy them I put up a short conventio

Any ballpark idea what the pitch should be?
