That is what I was talking about before even seeing the Wolf antenna and how it is made. The use of his loading coil alters the base feedpoint impedance. It is not possible to simply use only a gamma match at the base of a conventional 5/8 wave.A 5/8 needs a coil somewhere to basically extend it to an electrical 3/4 wave which is much easier to tune. Also the Wolf gamma match is not what I was picturing as I was thinking a match similar to that used on a yagi element.
