The M-330 is a Mini RFI Locator from Radar Engineers. This compact, easy-to-use tool locates power line sparking, which causes radio and TV interference. Designed for use by field personnel, the Mini Locator combines a sensitive receiver, analog meter, speaker and antenna in one hand-held unit.
Frequency and gain control knobs enable the operator to optimize reception of RFI signals. The four-element Yagi antenna provides additional gain and superior direction finding. A digital filter minimizes distraction of non-90 Hz sources.
