  Hi David, 4X1DG

  It is a long matter to explain in a few words so that in a separate email 
  I have sent to you the 5 MB zipped file of the following nice article:

  "The Advantages of Circular Polarization for Amateur Satellite Ground
  Stations" by John J. Nagle, K4KJ 

  I can send the above artiche to anybody interested to it.
