TABLE II.

Theoretical Q Values From Estimated Impedances Agree with Experimental Ratios of Reactance to Resistance. Measured Q for First Generation Design Matches Estimate Q That Includes Lead Inductance, Whereas for the Second Design, Measured Q is not Dominated by Lead Inductances. Ratio of Unloaded to Loaded Q Appears in Last Column
