RE: Sử dụng radar detector thôi
X-, K-, KA-Band Testing
The following tests were performed on a straight five mile stretch of roadway located in the desert, about 17 miles south of Wickenburg, AZ.
X Band Testing
(10.475 to 10.575 ghz) is the oldest radar band in use today. It is estimated that only 15% of the law enforcement radar guns still utilize this band.
The New Jersey State Police, several police departments in Ohio and the US Park Police are the only agencies Radar Roy knows of that use this band as their preferred radar band of choice.

K-Band Testing
(24.0 to 24.25 ghz). K-band was introduced in 1976 and currently this is 60% of the traffic enforcement radar used by police in the USA today.
Radar Roy utilized his Kustom Falcon K band hand held radar gun and affixed to a tripod at full power during this test.

KA-Band Testing
(33.4 to 36.0 ghz). Ka-band is the newest band and it is rare to have false alerts on this band. It is also harder for radar detectors to detect police radar devices on this band. Currently this band is 25% of the traffic enforcement radar used by police in the USA today.
Radar Roy utilized his Stalker Ka band hand held radar gun and affixed to a tripod at full power during this test.

* As the Super Stealth 9000 gave out a constant false alert reading on K band when the unit was powered up, Radar Roy was unable to determine the range testing capabilities of this unit.
** The RMR D-550 was almost as bad in falsing as the Super Stealth 9000. In 1 mile, Radar Roy counted over 35 false alerts on K band. Because of the large number of false signals, Roy was unable to determine the K band range
