Is it normal for a 13" gamma match
to only need 1-1/2" of rod insertion to obtain the proper capacitance?


Hi Russ,

It seems I ran across a short hand for the required capacitance for
the common gamma match that offered somewhere between 2pF and 5pf
times the wavelength of the band. That is, 12pF to 30pF - not much
especially if the rod is a close fit with a small dielectric layer.
