The ATVC-10 converter connects between an ordinary UHF antenna and the VHF input of any (analog) television set.
Features and specifications of the model ATVC-10 are a low-noise, high-gain RF amplifier stage with varactor-tuned input and outputs, an active mixer with varactor-tuned input, a varactor-tuned oscillator stage, and adjustable rf gain control.
The built-in ac power supply uses a transformer for power line isolation and a full-wave bridge, supplying a regulated voltage for the four tuning varactors. The converter is electrically tuned from 420 to 450 MHz, with outputs on VHF TV channels 2 through 6
