Another ham gave me a homebrew PI network tuner he used to tuning
single wire feed antennas. I'm planning to build a multiband antenna
and feed it with twinlead or ladder line since it's less lossy than
coax.

I'd like to make or buy a balun for this tuner. I don't plan to run
more than 100 watts, and will probably start experimenting with QRP
operating as well.

Any guidance is appreciated.
