If my antenna has a deep null at the favored angle, it is
there on both transmitting and receiving.

I think most cases of "one-way skip" are really other easily
explained very common effects, like high noise or poor
antennas.

Remember that antenna GAIN  and pattern is identical whether
receiving or transmitting. S/N ratio is not.
