[Moon-net] Polarity switching - 45 degree steps?

[Vic Nyman]

Hello all,

After more than a year off the air, an interstate move, and a new call  
K4UCY (ex K6UCY), I am planning the new station for the spring. I  
could use some experienced advice from the group:

I am planning to put up crossed yagis with polarity switching. I have  
been seeing references to polarity switching using 45 degree  
increments, but I have been unable to find practical references to the  
implementations. I have been able to design a couple systems myself,  
but I am certain that there must be better implementations.

Can someone point me to a web site or send me a document about 45  
degree switching configurations?

Thanks, Vic - K4UCY
