Absolutely not ... study "crossfire phasing" (W8JI term) or look for
information on frequency independent phasing.  For receive operation
flipping phase of alternate elements allows phasing to work across
a couple of octaves or more as long as the element spacing does not
become significantly greater than 1/4 wave at the highest frequency.

hears very well with the HiZ on 80 and 40 with it, but does not benefit
from the exceptional noise cancelling on those bands due to the length
of the phasing lines.
