Back to my question: I am measuring about 125 watts forward and 4-5
watts reflected at my desired frequency ( 146.000 ). While this may be
acceptable to some, I would like to get the match down to 1:1 SWR.

You could always construct one of the "fancy" and esoteric 50:75 ohm
ununs to accomplish, however, you would probably not gain much if
anything, as there will be some loss--even if you construct the unun
from optimum material.

However, if ONLY the mismatch bothers you (and not the insignificant 4-5
watts) and not the actual loss of watts--it is an option. But any
"gain" you would get from this option would be virtually
"insignificant", or so in my humble opinion.
