The Beverage Antenna, very
familiar to amateur radio operators, is a simple but efficient, highly directional, non-resonant antenna that
consists of a single straight wire of one or more wavelengths that is suspended above the ground. It is orientated
parallel to the direction of intended reception. One end is terminated to ground through a resistor, and the other
is connected to the receiver. The following quote comes from the patent (US1,81,089)
text (reference Fig. 3 in drawing below):
"In accordance with theoretical considerations, if an antenna were to be freely suspended and if the surface
of the earth constituted a perfectly conducting parallel plane, current waves would travel through the antenna
conductor at a velocity equal to the velocity of light. ... By choosing proper values for the condensers the wave
velocity on the line for continuous waves .of any specified frequency may be made equal to or
greater than the velocity of light."
Harold Beverage of Eponymously Named Antenna Type
Dr. Harold Beverage, recipient of Army honors.
It is the intention of the Signal Corps to present such certificates to individuals and companies who have
performed notable services beyond the normal requirements of duty but who are not under the direct control of
the War Department and are therefore, not eligible for the Army-Navy "E."
Several other certificates have already, been awarded to individuals and companies. Possibly the most notable
figure to receive one is Dr. Harold H. Beverage, old-time radio researcher and inventor, now an associate director
of the RCA Laboratories.
