Thank you for the response, folks. I appreciate it.

The swr is higher than I had hoped for. I was hoping to use a duo-
band 15/40 meter wire dipole that could be fed directly with 50 ohm
coax connected to my Yaesu FT-450AT with internal tuner.
But the FT 450 AT internal tuner will only match up to a 3:1 swr, so
that won't be "do-able".
Thank you again......

See QST Dec. 1991 Hints and Kinks. The author cut the dipole for the
low end of 40M~67' and used a Q section of RG59 cut for 21 MHZ to
improve the match on 15M.
