We seem to be going around in circles.  If different components of the
radiated signal arrive at a distant point with equal and opposite phases,
the net signal at that point is zero, right?  I don't think it violates the
conservation of energy to argue that some antennas may be more prone to
this sort of cancellation than others.  Moreover, why isn't it plausible
that such cancellation effects could be more prevalent in the forward field
than to the rear?
