Radar Detector K Band: What the Alert Means

K is a radar frequency band, commonly centred near 24 GHz in detector specifications. Some speed-measuring systems use it, but other devices can also trigger a K alert.

Vehicle safety sensors, automatic doors and other radio sources may cause alerts. A detector's filtering and GPS lockout options can help manage recurring sources, though settings differ by model.

K-band detector specifications commonly identify a frequency around 24.15 GHz; the exact coverage window varies by model. Check the manufacturer's specification sheet for the unit you own.

No. It indicates detected radio energy in a band that may include police radar, but the alert does not establish the source or its location.
