I built a 15 meter beam with the DE cut for 21.250.  The MFJ analyzer
reads 23.000 for a 1-1 match.  I added about 8 inches and the best SWR
is at 22.500.  These tests were made at 10 feet.  Will the frequency go
down when the beam is at 40 feet?  I can't believe that I have to keep
adding to the DE.
