Very confused over this manual tuner the MFJ 989D
The literature boasts of a built in 1:1 balun consisting of two large toroids. And on the back it accepts a balanced feed line . And the documentation says to hook up your balanced feed line.
OK, call me dimwitted, but I thought that the purpose of a balan is to balance an unbalanced feedline. What would be the sense in having a built-in balun if I have to feed a balanced line? So this means that I must already have a balun already in line of my 300 ohm landline before it hits the tuner?
Or am I just completely missing the mark here?
