18 kwi 2020 · A well-designed Z-match tuner has a high Q and is more efficient (less lossy) than other types of tuners. The fixed inductor simplifies construction (no taps or rollers needed). Using a toroid inductor and some small poly-film variable capacitors, the Z-match can be built into a very compact package.

My favourite antenna tuner is the single coil Z-Match. I tend to use ladder-line feeder instead of coax, so I believe a tuner designed for balanced feeder is a much better solution than a T-Match or SPC using an external 4:1 balun or similar.

I decided to build a homebrew antenna tuner because I needed a passive pre-selector network to match an experimental end-fed wire antenna to my QS1R SDR receiver. Please Note: In the last version of my modified FRI-Match (diagram above), I replaced the 470 pf variable capacitors with 500 pf. This Page Covers.
