[amsat-bb] Re: LHCP or RHCP?

[Bob- W7LRD]

Hi Tom-The vague answer is " it depends".  I have found that different polarizations are more effective on the same satellite during the same pass at different times.   Why that happens?   I have no idea, the answer to that is out of my pay grade.  I have a L & R switches and they get used a fair amount.  I am sure everyone else's mileage will vary.  This has been my experience.

On the premise that the only dumb question is the one that goes unasked, 
here goes. 
  
If I'm building an antenna of circular polarization for use with the birds 
what determines if it should be LHCP or RHCP? I've read the ARRL Satellite 
Handbook and "sort of" searched the AMSAT-BB archives but found nothing 
about this question. 
  
Thanks.
