Just a bit of anecdotal evidence to support Tom's latter point -- when I
measure the lowest-SWR point on my C-3 at the shack end of a long 75-ohm
feedline, it appears right where it's supposed to be - 14.225. When I add
2 feet of jumper and my SB-220 to the circuit, the "resonant frequency"
shifts to 14.450! Whatever else is happening, it's clear that the
antenna's resonant frequency has not changed.
