Half wave over a quarter wave, if the quarter wave is not in phase with the half wave and there is full cancellation then its a J-Pole I suppose, or simply a half wave linear. From the amount of gain this antenna has compared with a J-Pole it suggests otherwise, so maybe there is an element of colinear about it. Who knows, how do you know if the quarter wave section is radiating?
