Mike,

Interesting. Would you tell us how you conducted the A/B comparison tests. 
We hear a lot of conjecture like you said how "well' they work and how "quiet"
they are.  Please give us the facts on the test antennas and how the A/B tests 
were conducted and the data from the tests.  This might be worthy of a QST article..............
