If Station A is using a traditional horizontal Yagi in contact with Station B using a horizontal Yagi, via 50 mHz Sporadic Es or some form of F-layer propagation, either single or multiple hop, does

Perhaps it's just an "old wive's tale" but I think I once was taught (EM Wave Theory 401) that the F-layer, combined with earth reflections, tended to turn all signals into near horizaontal polarizat

Over an ionospheric path the polarization is changed randomly and is time-variant. There is no advantage in trying to match (or otherwise) transmit and receive antenna polarizations. Steve G3TXQ ____
