Model 243

RFI Locator

The Model 243 RFI Locator sets a new benchmark for interference detection, combining a wide band tunable receiver (500 kHz to 1000 MHz) with industry-leading sensitivity and clarity. Its high-resolution color display features split trace analysis, allowing users to compare live and reference waveforms side by side for faster, more accurate identification of power line sparking and other noise sources affecting HAM radio, AM, LTE, DSL, and CATV. Interference is visible, measurable, and audible giving technicians a complete view of the problem in real time. Use the Radar application to review saved traces conveniently on your computer, turning field data into actionable insight anytime, anywhere.

Designed for demanding field environments, the 243 arrives mission-ready with a carrying case, battery charger, mag-mount whip antenna, hand held directional antenna, and AM probe. Built for professionals who demand precision, the model 243 transforms RFI detection into a faster, smarter, and more decisive operation.
