Radar Detector Meanings: A Guide to Bands and Display Alerts

Display symbols are model-specific, but band labels identify signal categories and directional arrows can indicate where a signal appears to come from.

Radar detector meanings are easiest to understand by reading the model’s manual first. Band names such as X, K and Ka describe categories of radio signal; arrows, tones and counters are interface features whose interpretation depends on the detector.

Common questions

Questions before you buy

What do X, K and Ka mean on a radar detector?

They are labels for radio-frequency bands monitored by the detector. The frequencies and displayed behavior are specified by each manufacturer and can vary by model.

What do the arrows mean on a radar detector?

On detectors with directional antennas, arrows can indicate the apparent direction of a detected signal. Consult the manual for how your specific unit determines and displays direction.

What does a signal-strength bar mean?

It indicates a relative signal level as defined by that detector. It should not be treated as a precise distance measurement or proof of the signal’s source.

What does a bogey counter mean?

Some detectors use a counter to show how many signals they are tracking. The manufacturer’s manual explains what counts as a separate signal and how the display behaves.
