I have switched to many different receiving antennas on the high bands.
The ability to listen in many different direction with the array would
be a plus. It never fails that when I turn my beam to EU, AF or SA
call. I don't see why a circle or 4 sq array would not work on the high
bands. Finding the sweet spot for 20, 15 and 10 might be more challenging.
K3LR or W3LPL or others might have comments based on modeling.

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?
