RSGB Convention lecture 2016 - Polarisation of 50MHz signals

RSGB Convention lecture 2016 - Polarisation of 50MHz signals.

At VHF we tend to assume that our signals arrive at the other end with more or less the same polarisation as they left with, whereas at HF it’s commonly believed that polarisation is effectively ‘scrambled’ as a signal goes through the ionosphere. But how many of us know what’s really happening to our signals, particularly at the ‘in between’ frequencies like 50MHz? Chris Deacon, G4IFX will introduce polarisation effects and why they are important, and will then describe early results from his ongoing research into the polarisation of real received signals at 50MHz.
