the radiator is too long for resonance @ 50-54 mhz.. shorten the radiator until reactance equals 0 at the preferred frequency. check the match and readjust the gamma as necessary, check reactance and readjust for X=0 if necessary. repeat procedure until R=50 jX=0 at the preferred test frequency. once X=0 the impedance will present a non-reactive, purely resistive 50 ohm load.
