Can a 20 meter yagi be tuned down to 10 meters? can a 40 meter yagi be
tuned down to 10?

And don't forget that a new gamma match must be calculated. See
http://www.ve3sqb.com/ and search "gamma" on the page for his antenna
design program "Gamma".


Yeah, most of have explored those "ballpark" equations/formulas for
gamma matches. I even translated one from the basic language to C.

In the end, it is "cut and match."
