The Leader LFC-945 is a signal level meter of service use for field strengrh measurements of broadcastings of VHF and UHF television, CATV, and FM radio. The instrument covers the measurement frequency bands of the VHF (40 to 300MHz) and the UHF (470 to 890MHZ) and the 75Ω termination peak level of the input RF signal can be corectly read by the sum of meter indication and attenuator setting. Further when 50/60 Hz AC voltage is superposed on the television RF signal with the output of the common receivers amplifier, the signal level can be measured by the F-type jack for the RF input signal. The LFC-945 has a wide range of applications, including the measurements of receiving levels, measurements of field strengths, TV and FM antenna selections, antennas installations, directivity determination of antennas, boost amplifiers gain measurements, master antenna television distribution system laying, and home antenna distribution construction.
