[Antennas] Mag Loops

OOPS, sorry about that - the URL should make this much more interesting!
Loop arrays have been in professional use for several decades.
Take a look at this U.S. manufacturer for professional quality loops and
some illustrations and specifications for arrays of receiving loops. I
imagine that the price would be well out of the range of most of our
budgets!

My old second hand Wellbrook loop significantly outperforms my vertical
and inverted L, especially on the lower frequencies and a small rotator
allows me to null out QRM and QRN. It works well from at least 20kHz to
50MHz. Although the pattern varies somewhat as the frequency is increased.
