I have a z match tuner and two conventional "link" coupled
tuners....home made.......they all work as good or better than any of my
3 commercial t tuner with balun designs. (Yes, I own too many tuners!)
The z match is not as easy to use (more finicky) but seems to match a
greater impedance range. But, what do I know......just my .72 cents
