Dave,
In my years as an RF technologist, I helped design high power amplifiers
from prototype to first article. We almost always "tuned" our components at
low power first and then tested them at high power. The results between low
power and high power were almost always identical with the exception of the
loss of power at the high end of the band. Typically, they worked just fine
though. If you have a freq generator, then I would suggest that you follow
Bob Jude's suggestion and sweep the entire bandwidth.....especially if you
have a homemade antenna.

All,
Another question for the antenna guys:
If I were to have a frequency generator and sweep the
frequency of interest to test the power transfer and
I did it a a low enough power so as to not to interfere with
any local users of a frequency, would the low power results
be identical to higher power results?
