Topband: Found my K9AY by WX0B AX-AYl-4 unit

[Steve Sacco NN4X]

I concur with Tim's comment, below.  With a K9AY loop array, you're 
really pointing the null much more than the forward lobe.

Additionally, I've noticed that when there is high angle QRN (generally 
T-storm activity from wherever), my K9AY loop array is not especially 
useful, and I can't get a null on the noise in any of the four 
directions.  Without that kind of noise source, it works well.   It's 
not as good as my 700' Beverage, but I'm glad to have it available.

73,
