Unless, of course, the station uses parasitics -- but I don't believe
any U.S. station is licensed to do so. Some stations elsewhere do,
however; PJB in Bonaire was formerly one example: one tower was driven
by the 500-kW transmitter, and four towers surrounding it in the near
field were tuned or detuned to provide the desired directional
pattern.
