Abstract
A signal strength meter/indicator for use with an over-the-air broadcast television signal receiving antenna includes an input bandpass filter circuit, a first preamplifier circuit, a controllable variable attenuator circuit, a second preamplifier circuit, a splitter, an output bandpass filter circuit, a VHF/UHF filter circuit, a power detector circuit, a microcontroller and a display. The microcontroller, the controllable variable attenuator circuit, the second preamplifier circuit, the splitter, the VHF/UHF filter circuit and the power detector circuit together define an AGC circuit which adjustably controls the power level of an output signal provided to a television. The display is also adjustably controlled by the AGC circuit in displaying an indication of the relative signal strength of the broadcast television signal received by the signal receiving antenna to provide more accurate measurements and indication of the relative signal strength of the received broadcast television signal indicated on the display.
