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.


What you have is a *physically* short antenna that is *electrically*
1/4WL long. This usually involves a loading coil.

Also, the electrical length of a piece of coax is longer than it's
physical length because of the velocity factor less than 1.0.
