A Balanced Balanced Antenna Tuner
As a rule of thumb, a balun should have about 4 times as many reactive ohms as the resistive ohms of the load. This means that for use with a 600ohm balanced load, the balun should have a secondary winding reactance of about 2400ohm

Automatic Tuner Project
I have been accumulating parts from ham swap meets for several years for a medium power antenna tuner. The tuner is a high pass T-network tuner

A Homebrew Z-Match Transmatch
The coil was wound using some #22 solid hookup wire (from Radio Shack) which I had lying around. The secondary winding is wound between the turns of the primary to ensure tight coupling
