50 watt z match tuner
- The result was a tuner that will work 10 thru 80 meters and handle up to 100 watts of RF. I originally thought that the variable capacitors that I had would handle 100 watts, but then found out that they will arc over on 80 meters at the 100 watt level. So I backed the power down to 50

The super tee qrp Antenna Tuner
The SWR bridge reads the reflected voltage, and thus it must be tuned for a minimum light output from the LED
The MFJ tuner with the motor drive attached
This project uses some small gearmotors purchased from Hobby Engineering to drive the inductor switch and the two air variable capacitors on an MFJ 1500W antenna tuner
The Z-Match Antenna Tuner
Charlie's Z-match ideas below have been implemented in my station as my compact portable antenna tuner
The Dentron AT-3K Antenna Tuner
AT-3K only has a switch position for balance line BAL to feed to an external balun
