Description (Brief):
First television for home use. 10" aluminum-mounted lens and 45 degree mirror mounted on mahogany case. Contains drum scanner. This receiver was used for the reception of "Radiomovies" and television in the home. It makes pictures that appear about six inches square and uses a four-cathode neon radio-controlled lamp, a helical-aperture scanning drum and quartz rods to carry the light from the lamp to the apertures in the drum surface. It was called "Radiovisor" by Jenkins to indicate that the signal was over the air waves; television, as he stated, was the word used to indicate that the signal was carried over wires. Reference: "Radiomovies, Radiovision, Television", by Jenkins (pages 62, 63, 64).
