The radiation patterns for a 1/4 and a loaded 1/8 wave should be
slightly different.

If so, ERGO! Two different antennas.

Boy, this stuff is tough! :-)

Is an antenna that is resonant on 10 meters still a 1/4 wavelength antenna
if it is physically only 4ft long or would this be an 1/8 wavelength
antenna(more or less).I am saying this should be called an 1/8 wl antenna
though I am arguing with those who generally know more more about this than
I. Not all the old timers disagree with me, so I am betting this is a pretty
common problem when discussing antennas.
