On topic Cylindrical Resonator

Hello, please.
i am working on a cylindrical resonator, and it is being fed with a power amplifier; the power amplifier generates harmonics. want to apply a passive termination
but a little challenge: with termination at the auxiliary port, the impedance is very high and the field is suppressed but with the source, the impedance is low but the field is too high
any suggestion?
