Changing the beam
This switchyard is one of eleven places in the US where US radio propaganda takes off for foreign parts.
It is at General Electric’s 100-kilowatt shortwave station WGEO, Schenectady, NY. The switchman with the “fish pole” is changing the beam. He moves the wires which will be loaded with the program from pole to pole according to the destination desired.
Each pole has antennae beamed (aimed) constantly, like a searchlight, at a specific country or continent. (Ordinarily the beam is shifted automatically.)
