And, the source for such 600 ohm line and doublet is:
Go for the one with 240 of wire each side of center; cut
it shorter, or as Chuck suggests, droop the ends. I am
using one of his 125 foot set ups. Operates just fine for
me on 80, will on 60, 40, and 30. Have not used it
on the higher bands. I feed it with a very old Johnson
Matchbox tuner, which is balanced without using a balun
See if you can find one of those. They are around.
I have checked mine on 60 with the MFJ 259 analyzer; it
will tune there just fine using the 80 meter secondary
coil tap of the Matchbox.
