  I might have agree with that last year.  The ground conductivity
here is very high.  Last year my Beverages generally were lucky to be
as good as my parasitic vertical array for reception to Europe.  Since
then I improved my transmit antenna's European director and I have
received better reports from Europe on its performance.  I also have
changed my Beverages--lowered their height to about one meter above
ground, changed matching on coax to some, changed some lengths, and
changed the termination resistance a bit.  This year I rarely saw
improved reception while using my transmit antenna...

What software was used?  To quote from a response that I received
to my past topband posting on modeling Beverages from K6STI:
