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 the 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.
