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.
