Multi-Band Jammer Detector

Selective jammer detection for professional, fleet and fixed-site monitoring. Designed to detect abnormal in-band RF conditions rather than simply respond to every nearby RF transmitter.

Band-selective detection: ordinary broadband RF detectors can alarm on legitimate phones, radios and wireless devices. RF Guard Pro restricts detection to the relevant service bands. An alarm indicates an abnormal in-band RF condition; further investigation may be needed to establish the source and intent.
