For several years, I've been using my multiband non-resonant 94'
doublet, fed with a short run of 450 ohm window line, to a remotely
mounted SG234 autocoupler and then a 25 foot run of 50 ohm coax to my
KX3.
Has been working with perfection; no complaints, except I cannot operate
QRP below 3 watts because that's the minimum RF required for the
autocoupler.
Now, if I wanted to extend my 450 ohm line and connect it directly to
the KX3 and use the KX3's internal tuner, would there be any benefit in
a 1:1 isolation balun at the KX3?
I can't think of any reason this would be necessary except as a
transition from the window line to a convenient coax output to the KX3.
What would the KX3 prefer??
Thanks,
Stan WB2LQF
