Because most of the CMC has already been radiated off the resonant 1/4 wave cone, very little happens if we take the time to insulate the base and add the coax choke. I've been able to measure virtually no change in impedance and the slightest drop in gain when doing this. That is due to the fact that any remaining CMC on the mast and coax would be in a constructive phase closest to the feedpoint connector.
