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.
