Shown here, on the cover of the June 1953 issue of Radio-Electronics, is Barbara Reid, a worker at General Instrument in Elizabeth, NJ.  She is making adjustments on the company’s Model 60 UHF tuner, which was in turn used in a number of manufacturers’ sets to tune channels 14-83, 470-890 MHz, which had been allocated to television in 1952.

According to the magazine, this band was an awkward one. The frequencies were too low for microwave and radar techniques, but too high for lumped-constant circuitry.  Accordingly, this tuner, which found its way into sets made by companies such as Dumont, used a combination of both techniques.
