Been looking at some antenna designs and have one I plan to build. It is a tuned loop antenna. Haven't quite decided on how to use it, but I would likely carry it like a backpack and I might try to add one inductor loop and hook this up to the L-rods. The idea here is hopefully it will give off a stronger signal.
I would like to build one for extreme low frequencies but it's a lot of copper--one guy used 20Kgs of copper! So instead I decided to bump up the frequency into the 62K area to save some money and weight. A square frame about 2.5 feet on a side gives about 10 feet per wrap and I need 100 turns or 1000 feet of wire.
Like i said, I am no electronics expert, but what I have read about the magnetic component is strong in the first quarter wavelength--this might not be "strong" but it's there. Unlike the Witricity where the wavelength is only 30 meters, most MFD's run into the miles. I would like to learn more about the Witricity as I think there is something there that will be very useful for locating.
