Different Radar Bands Explained
Police Radar Bands
X-Band (10.500 GHz – 10.550 GHz)
This is the oldest of the current frequencies used and false alerts on this band are plentiful. Its lower frequency and higher power cause X band to travel far and be detected at long ranges.
K-Band (24.050 GHz – 24.250 GHz)
K band is more commonly used now than X. It was first introduced in 1978. While not as many things cause false alerts on K band as they do X, there are still plenty of automatic doors which use this frequency.
Ka-Band (33.4 – 36.0 GHz)
Ka is the most recent of the bands authorized for use in the United States. As the highest frequency, it is the most the difficult to detect. Although over 2GHz of spectrum are set aside for Ka[Super Wideband], units currently being manufactured in the US centralize around 33.8, 34.7 and 35.5. The fewest false alerts occur on Ka-band and every alert should be taken seriously. The most common cause of Ka false alerts are low quality radar detectors. It’s is important to note these centralized bands because this is where radar detector users can use band segmentation on their Beltronics STi-R Plus, and Escort Redline detectors to fine tune sensitivity for the latest alert notifications at great distances.
