Hi, I read few remarks like this in last few months on TB reflector: Just curios - what is the physics/mystic behind? Different laws on 160 than 80? Distnace to ionosphere is very different? RU1A guy

I'm convinced that the reason verticals play so much better on 160 than their vertical and horizontal patterns suggests is related to the way vertically and horizontally waves propagate on 160. 73, J

Arunas, There's nothing mystical about it. It's all in the physics of a plasma (the ionosphere) immersed in a magnetic field. The polarization effect is tied to the electron gyro-frequency (the frequ
