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

And I just found this, where K5UO seems to say that his Slinky was about 12

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?

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

I'm planning on putting up some Beverages for the fall season...primarily
for use on 160. Unfortunately, they have to be taken down again in the
Spring for crops. The good news is they can be any length up to around
1200-1300 feet.
Many have said that around 880 ft is the sweet spot. Is
I'm sure it varies a lot from QTH to QTH, but here, over mostly volcanic
ash and sand, I could see significant difference between 800 foot and
1100 foot.
I never got around to trying longer than 1100 because I could not work
all that I could hear with those.

I actually tried this and discovered that any wire beyond
400 feet made no difference whatsoever. This is because
