polarization of 160 meter FT8 signals

[David Lonard]

Hello everyone,

Here is a polarization analysis of FT8 signals at 1.84 MHz using a pair of orthogonally oriented magnetic loop antennas. It is clear that different stations have their own distinct polarization in the phase plots which are the images that have a mostly smooth cyan background. The color represents difference in phase angle between the two antennas. 

Some FT8 stations hold a constant phase, while others turn.

A power spectrum is also included.
