Horizontal Polarization for VHF/UHF DX
Whenever people do weak-signal work on VHF and UHF frequencies, it's always done with horizontal polarization. I'm trying to understand exactly why in the context of some long distance packet radio experiments I'm currently performing. Looking around the Internets, I find answers ranging from "you use horizontal polarization for weak signal VHF/UHF because that's what everyone else is doing" to various justifications for its superiority. Note that I'm discussing weak-signal work via e.g. troposcatter and diffraction, and not Es, meteor scatter, or EME.
Here are some of the answers that I've seen:
