Hi we enjoy a relatively high level of propagated QRN here right up through 30 
mHz. We have some good transmitting antennas that certainly help but even using 
stacks we get some very deep mid-angle nulls with our flat Fresnel zone. The 
phased vertical rx arrays look very attractive with a beam width comparable to 
our yagis but a much nicer elevation profile and F/B. Plus the ability to 
switch directions very rapidly. The downside might be their low sensitivity 
below 6-7 degrees elevation compared to the high horizontal antennas.
Does anyone have experience using rx arrays on the high bands in contests?
