There are some on here who insist that the 8 inch stub is the actual 
radiating stub.  I say they are dead wrong. I have duplicated this with a 
8-10 inch stub to a 100 ft long wire and taking an 11 watt fluorescent 
light walking the length of the wire seeing the voltage peaks and nulls, 
proving RF is present on the horizontal portion of the wire, thus it also 
is a radiator.  Maybe the theory of 50 years ago might have been true, but 
actual observation disproves this myth.  Yes a long wire does radiate over 
its length. It is funny that in the 1920's a long wire was the antenna of 
choice as it gave more capture area.
