Domenico,

Thanks for sending the K4KJ article.

However my question was why does STRaND1, which only has a whip antenna, 
sometimes appear to exhibit circular polarity characteristics?  I would 
expect a whip antenna transmitting from space to have the same signal 
strength on the ground using either RH or LH polarity on my receiving 
antenna.

Ken, W7KKE

Hi Ken, W7KKE

The answere to your question is clearly described into the zipped article
"Circular Polarization" by K4KJ, 5 MB long that I have sent to you in
a separate email.
