J-Pole antennas are a 1/2 wave element with a 1/4 wavelength matching stub.
The Matching stub allows the dipole to be fed from the bottom end without
interference from the feed line. Open Line (J), tapped coax, or LC Circuit
can be used to match the dipole to a coax at the end, accomplishing the same
performance, including the same overhead null one expects from a vertical
dipole.
