I am planning to build a magnetic loop antenna and
feed it by means of a gamma match. I understand
that a gamma match will work over a wide range of
frequencies. I hope to work a number of bands using
the same loop.

My question is -- when I'm ready to test the antenna
do I adjust the gamma match at the lowest frequency I
plan to use, or the highest?

I have considered other forms of coupling the
rig to the transmitter but prefer to use the gamma
match.

Thanks in advance for any assistance or advice in this
matter.
