The Heathkit HD-1422 is an antenna noise bridge. It is used to determine how well an antenna is matched to a transmitter. The instrument works by generating a tone-modulated broadband noise signal and coupling it to an impedance bridge. Using a receiver as an indicator, the impedance bridge measures the resistive and reactive components of the antenna.
Front Panel Range: Resistance: 0 - 200 ohms; Capacitance: +/- 60 pF
