Postwar American Television
Postwar VHF Boosters
Early sets had very poor sensitivity. If the set was located more than about 30 miles from a TV station, the picture would be snowy. RF boosters were often used to increase the sensitivity. The unit on the left was made by Astatic, and tunes channel 2-13. The one on the right is a very early one, made by Video Research Corp. about 1946, tuning only channels 1-6. It was donated by Charles Harper of Paris, KY.
RMS model SP-2. This booster is from 1946 or 1947, and tunes channels 1-13. It uses two 6AK5 tubes.
