Given I am currently using 75 ohm coax to feed my random wire, I
believe I could use a 300 ohm to 75 ohm (4:1) TV twin lead to coax
converter and get away with it.

Mike, I used a 1:9 un-bal transformer, Its early and I'm rushing ,
but, 9 turns trifilar IIRC on an T50-2 toroid. the endfed was about
65' long. I fed it with 75R coax with the ground side of the unbal
going to the screen of the coax.


a bit like this (ant -u-u-----u-u--coax--u-u--gnd )
where --u-u-- is a winding of the unbal.

It worked reasonable well with 10watts on 40m and above using an atu,
but had problems with 80m due to RF feedback. A counterpoise from the
unbal gnd would probably have helped this.
gotta go.
