Just for fun I set up my frequency generator at 60KHz and held my AM tuned loop antenna (seven loops of wire on a 2 1/2 foot square frame) as I walked back and forth searching for the signal line and tuning the antenna on each pass. I ended up holding the antenna downwind and perpendicular from the transmitter. I tuned as best I could and did not see any improvement in signal strength but I did notice the coil felt like I was holding a shield (to block anything from downwind) so I only concentrate on the line back to the transmitter.
So then I thought about a parabolic shaped spiral wound antenna for the 60KHZ. One-hundred loops of wire would look like a giant spider web.
