[TowerTalk] 2 antennas

[Gary Schafer]

I haven't tried it on 80 but I don't see why it wouldn't work there too. 
I did do that on 10 meters. Mounted a vertical element on the 3 element 
beams boom. Phased them with proper length lines.

I tried right hand, left hand circular and could see quite a difference 
when switching as the propagation rotated. This was at times when 
signals were fading badly on either horizontal or vertical mode. I set 
up the circular polarization to try and confirm that the propagation was 
indeed rotating and not just fading of one polarization. The circular 
confirmed that it was rotating as when it would fade on right hand, left 
hand would be much better etc.

I found that running both vertical and horizontal in phase smoothed out 
the fading at the cost of around 3 db with both antennas together. With 
that setup I did not have to continually switch polarization.

It made such a difference that with just horizontal or vertical, at 
times the signal would fade into the noise. With the 2 antennas signals 
did not go into the noise.

At times of little fading the horizontal beam worked best by itself.
