John, don't forget to add in the increased loss of the vertical as well when
you compare performance. I saw a thorough analysis some time ago by one of
our UK friends (not HM <G>) that places the comparison under 2 db. Lots of
factors in play. I'll see if I can dig this up.
Hope to be able to test this first-hand in the near future. XX XX (fingers)
