MINI RFI LOCATOR

The M-331 Mini Locator delivers interference detection in an ultra-portable design.
Purpose-built for field crews, it integrates a high-sensitivity receiver, calibrated LCD signal meter, speaker, and four-element Yagi antenna into one handheld unit. Optimized for gain and directional accuracy, the M-331 enables technicians to quickly pinpoint sparking power line hardware that disrupts radio, television, and data signals.

By scanning lines and tracking peak noise readings in decibels, the M-331 makes pole-to-pole comparisons fast, accurate, and repeatable. A frequency/RF gain control, digital ignition filter, and selectable dB readouts ensure precise measurements in varied environments. Built to resolve interference affecting communications, broadcast, and broadband systems, the M-331 equips crews to restore signal integrity whether the source is an arcing hot clamp, leaking lightning arrestor, or cracked insulator.
