The U.S. Department of State uses many of these B&W folded dipoles in
Africa and other nations with HF transceivers meant to be used by those
with little or no radio operations experience. All the user needs do is
consult a list of places and frequencies (which are all programmed into
memory), key the microphone and talk. These antennas weren't made to
work DX and neither were the transceivers. Any easy way to make up for
the inefficiency is to switch on one of the 500 or 1000 matching
amplifiers, none of which requires manual band switching or tuning up.
