"Why don't every American have this aerial ? It is beyond Big!"
Yep, big... and expensive. Probably two good reasons why not all of
us have one. Never used one so can't say if it's any good or not. I
have used loops (big ones) made of wire and I like the results. A
single loop, all by it's self, has no appreciable directivity.
Certainly possible with another 'element', or something near it, but
not just by it's self. Sorry 'bout that.
