What X band means
When a radar detector displays X band, it identifies a radio-frequency range rather than a specific police device. Exact band limits and signal processing depend on the detector.

Guide
What Is X Band on a Radar Detector?
X band is one radio-frequency band a detector may identify. Its local relevance varies, so understand the setting before disabling it.
What the detector can receive
Uniden lists 10.525 GHz for X band on the R8 specification page. This is a model specification, not a claim that every jurisdiction uses X-band enforcement.
X band, K band and Ka band
These are distinct radar bands. A detector may show the band alongside signal strength, but the display alone cannot identify the source with certainty.
Should you disable X band?
Band settings are a trade-off: filtering a band can reduce unwanted alerts in some contexts, but it also removes alerts from that band. Consult your manual and avoid assuming nationwide uniformity.
Common questions
Questions before you buy
What is X band on a radar detector?
X band is a radio-frequency band that some radar detectors can receive. Uniden lists 10.525 GHz as its X-band frequency; whether local enforcement uses it varies by area.
Should I turn X band off on my radar detector?
Only consider changing band settings after checking the detector manual and local enforcement environment. Disabling a band can prevent alerts to signals in that band.
Do police still use X band radar?
Use varies by jurisdiction and can change. A manufacturer band specification does not establish which equipment a particular police agency currently uses.
Is X band the same as K band?
No. They refer to different frequency bands. Uniden publishes X at 10.525 GHz and K at 24.150 GHz for its R8.
