I agree --- larger the resonator the better. There is a 20-25% gain going
from 3-4 inch dia to 6-10 inch dia resonators. This also scales up. Ed
Wingate's 24 inch dia. resonator works about 20% better than one of our
standard 18 in dia resonators. The larger resonators also seem to generate
a lot less standing waves kicking back into the pri side of the circuit.
Think big!!!
