How about using a slip ring coupler for the wires and spinning the loop to
obtain an omni directional pattern??? Maybe just spin it at 1 RPM or
something slow anyhow.
Thanks for trying it in the horizontal position. Now we all know the truth
to what has been said before about horizontal LF antennas not radiating
worth a darn.

Lloyd, Larry, Dex, John, Mitch, and others:
Thanks for looking at these signals. The horizontal loop orientation
resulted in at least a 20db reduction in signal strength from the vertical
position. This appears to be the case for both surface and sky wave signals.
If you haven't had the chance, look at Lloydss's set of captures. A good
deal of the time there is no test loop signal at all, while the big loop
signal is strong, but it does come through at times. Dex, I have yet to look
at your captures. The net here is all jammed up and they don't seem to come
through. Will check later.
It's possible that the reduction could have been even greater if the loop
had been more precisely mounted and/or the location had been a good distance
from the house or the other loop. I guess it could be said that the
operation was a success but the signal died. :~) Sorry Mike.
Any requests for other tests? Elevating the loop to 600ft? Burying and
operating under the snow? Encircling the house with a 3/4" pipe (using
existing plumbing for the lower section <G>)? Bob: I still have that 'tilt'
idea in mind. BTW, using the big loop as a reference signal appears to work
really well.
