** A high Q suppressor shifts the dissipative burden onto R-sup that a
L-sup made with resistance-wire would have have otherwise dissipated. In
other words, what is not dissipated in L-sup must be dissipated in R-sup
in order to obtain the same reduction in vhf gain.

** in order to be lossy at vhf, a suppressor must be somewhat lossy at
29MHz.
