... unlike tropos, where you can expect to see the polarization uneffected.

Subject: Re: [TowerTalk] Polarization: Quad vs Horizontal at 50 mHz
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.
