It's measurably better than a tuner in terms of near-field strength;
14 turns of #12 insulated copper wire on a ferrite toroid ripped from an R7.
How much coax is needed for that transmission line transformer?
Mobiles are so inefficient, I'm always looking for that last 0.1 db.

Got any idea what the efficiency of your autoformer is?
I'm assuming a single coil for a primary, tapped down for
the load. Would a 4:1 transmission line transformer be more
efficient over all the bands?
