Band-selective jammer detection equipment.

Passive detectors for GNSS, cellular and Wi-Fi jamming. Unlike low-cost broadband RF detectors that respond to almost any nearby transmitter, this range uses dedicated RF filtering and per-band detection to monitor the service that actually needs protecting.

Product family

One common platform, configured for each application.

The display, RTC, logging and control electronics are shared. The RF filter population and firmware profile determine the monitored services.
