Yagis, when made of almost anything but something like nichrome wire,
are very efficient. Aluminum element yagis run in the high 90's of
percent efficiency when properly designed.

My bet is that you aren't speaking of efficiency at all, but something
you don't know the words to express. Try to explain what you mean, and
this group may be able to help you.
