Z-Match Antenna Tuner

This Z-Match is a link coupled all-band tuner. Two all band tank circuits cover 3-14mhz and 14-30mhz. The tank output links are selected with a very heavy duty SPDT rotary switch.

In addition to the basic Z-Match circuit, the tuner houses a 1KW dummy load, a Heathkit SWR/Power meter, and an antenna selector switch. Coaxial output from the radio can be switched to three seperate 50 ohm coaxial outputs, or into the tuner which drives ballanced ladder line.

The schematic can be found here.

Note, when you click the blue word here, the schematic will be presented in a new browser window. To get back to the project page just close the schematic window (click on X ). You can get a decent copy of the schematic by saving it as jpg and printing it.
