Danny,

I've never built a balanced L tuner so I admit I'm speculating. The
link coupled designs I've built seemed much easier & simpler
mechanically & they will give 1:1 if the taps are in the right place.
Just takes some intial fiddling to find the right places but once
that's done you're good.

I'll agree the double L's seem to be just as easy to tune but the
building always deterred me.

Have you ever measured the balance of your double L at various
freqs. (current on each leg of the feedline)?

I wonder if you have built a balanced L tuner? I made mine using only
hand tools and a drill press and had no problems. Also why do you say
they are a PITA to use? I adjust mine using only two knobs - the same
number of adustments I use on my Matchbox. Yes, I have both tuners.

Also, just how much of that terrible inefficiency and power loss does
that balun have? In the link you gave the balun consisted of nothing
more than a length of coax. There would be even less loss using a W2DU
type balun in that it requires a shorter length of coax.

Additionally, my balance tuner will give a 1:1 match on all the HF
bands (and anything in between) - something the Johnson Matchbox will
not do.

So are you talking from experience or just hear say?
