Here is a nicely done homebrew antenna tuner. It looks to be well thought out and constructed. It features a Roller-Inductor and 2 Variable Capacitors. One of the capacitors is of the split-stator type. This unit looks like it can handle about 300 to 500 watts of power. I suspect that this tuner uses the "Ultimate Transmatch" circuit as designed by the late Lew McCoy, W1ICP, but I'm not sure of that. Here is a link to the original article(in PDF format)about this which appeared in the July 1970 issue of QST magazine, and it is interesting reading: http://www.arrl.org/tis/info/pdf/7007024.pdf#search=%22ultimate%20transmatch%22 Please feel free to write at any time with questions. Thank you very much for looking and good luck! (please look at our rules and privacy policy) |
