Zack,
That got me close. When I set the length to 137' and changed from inverted V to horiz. dipole at 60' I got great results. Again, thanks for your help.

Thanks, Zack. I put in the numbers you gave me and the lowest SWR I could find was 2.5 at 3.9, 6.0 at 7.3, and 6.0 at 14.3.
I've tried all sorts of numbers without much luck and haven't seen any coordinates that give a good swr at 200 or 300 ohms.

I entered the parameters of the OCF dipole listed in the latest Antenna Book and ran it on 4nec2 modeling software, using specified lengths (45.3' & 84.7'), a height of 66', sloping to 33' and 14 gauge antenna wire. At an impedance of 200 ohms it gives high swrs on all the bands. Any suggestions?
Thanks, Gordy - WA2RUP
