Discussion on "Design Procedures for Pi-Network Antenna Couplers" (Leo Storch)

J.E. Wolfe states that he is unable to agree with him as to the equivalence of Fig. 1(a) or (b) and (c). These may be equivalent as far as impedances are concerned, but if so, then I do not believe that they are equivalent as to QL. If this is true, then equation (1) is in error, also. The original author (L. Storch) replies that Professor Wolfe's troubles stem from his failure to differentiate between the Q of the circuit with the load connected, designated as loaded Q or QL, and a Q which is solely a figure of merit for the coil and should be as high as possible. The author then provides an explanation where it it is convenient to label Prof. Wolfe's QL as QLW, in order to distinguish it from QLS, i.e. the QL of the original paper.
