I used to be good at this stuff, Cecil, but that was long ago.
The only balun that has worked with any success so far has been the built-in
balun (4:1 allegedly) in my MFJ-989C. That I can get to work. When hooking
up other baluns and using the coax output on my tuner, none of the other
baluns work worth a hoot with one exception. I have an LDG 1:1 200 watt
balun that will tune my Van Gordon All Bander from one end to the other of
the HF spectrum, using just the internal tuner of my Yaesu FT-890AT. Go
figure.
I used to be a fairly sharp cookie at this stuff, but those days are in the
past. Got a serious case of "brick brain syndrome", if you know what I mean?
To my way of thinking (which is probably incorrect), using the 4:1 balun
would broaden the impedances that I could match versus the 1:1 balun. What
you are saying is just the opposite. Please elaborate. I will be most
grateful.
