Just as a basic experament, I tried building a loop antenna out of a hoola
hoop.

I wrapped 4 turns of 24 gauge (cheap speaker wire) around a hoola-hoop.

While the antenna "worked" it didn't have the directional properties I had
expected. It basically seemed as though it was just a plain wire antenna.

Rotating it or placing magnetic materials inside of the loop seemed to have
little or no effect.

Could it be that I used electrical tape to hold the wires in place? Could it be
the curve of the tubing? (Unlike a very large diameter cardboard tube or spool,
with a flat surface, the wires aren't flat they're on a curved surface (plastic
tubing) making a circle. I hope I'm explaining this right.

How does one determine the number of twists to use?

Anyone else try this with success?
