Radio’s Warning Lights (Nov, 1931)

Radio’s Warning Lights

RADIO masts, towering hundreds of feet into the air, present dangers to the aviator like the unseen “snags” of the Mississippi to the steamboats of old days. However, with powerful illumination of the kind shown here, they become beacons to guide tlie pilot who is familiar with their positions.

The type of light shown here, with its six radiating neon tubes, is especially visible from above. Such lamps have recently been installed on the masts of the new transmitter of station KDKA, at Saxonburgh, Pennsylvania, near Pittsburgh.
