[amsat-bb] Re: Arecibo and circular polarization using cheap yagis

[i8cvs]

Hi Rick, WA4NVM

Plese look at the two last drawing of the SV1BSX page:

http://sv1bsx.50webs.com/antenna-pol/polarization.html

You will see that the polarity marked (+) over the dipoles are correct for
both the clockwice CW or RHCP polarization as well for the counterclockwise
CCW or LHCP polarization.

By the way the drawings of the circular pats of the wave along the antennas
are wrong and must be inverted. The green path on the top picture is LHCP
and  must be inverted with the red path in the bottom picture  wich is RHCP

Sorry I can't informe my very good friend Mak SV1BSX because unfortunately
the last year he went SK but he did a very beautiful job.
