Z-match tuner for ft817
I chose to use the dual balanced output link configuration suggested by Mr. Lofgren. One link is a low impedance, the other a high impedance
Z-match ATU covering 160m - 10m
I put up a homebrew 40m coaxial dipole which wouldn’t even give me a good SWR on 40m! I looked around for an appropriate ATU circuit to build

The two transformers that need to be wound, one on toroid and the other on a binocular core, were pretty easy, and anyone who has wound inductors before will have no problem
Z-Match, un circuito da riscoprire
L'originalita' dell'idea consiste nell'usare due circuiti accordati, in parallelo, che lavorano su frequenze diverse, eliminando la necessita' di induttanze tipo roller o con prese commutabili
