?  A vhf suppressor partly de-Qs the anode-resonance by stagger-tuning 
it.  This is accomplished by having two current paths of differing L,  by 
aiming the two electromagnetic fields 90-degrees apart, and by causing 
roughly equal vhf current to flow in R-sup and L-sup.  Naturally the 
differing L requirement depends on there being a substantial lack of 
inductance in R-sup.   According to N7WS, the resistors we use in our low 
vhf-Q suppressor retrofit kits have approx 11nH of intrinsic L.
