The dipole antenna, how industry defines it

All dipole antennas... according to the IEEE

Is a dipole antenna defined by its behavior alone or also how one energizes it? The answer exists in IEEE and historical literature.

1/2 Wave vs. 5/4 Wave VHF EZNEC Shootout

A friend of mine is preparing for the upcoming Virginia QSO Party in March 2009. Part of the preparations include a focus on some good VHF antennas to support the heavy use of VHF mobile operations in this party. Vertical polarization is key to success. He spoke of a 5/4 Wave Antenna.

Unfortunately, one web site promoting a 5/4 wave antenna solution failed to realize you can’t make an antenna longer without eventually hitting a limit.
