Page 8 - Performance Is KingBells and Whistles Don't Matter It doesn't matter how many bells and whistles it has, or how stylish it is if a radar detector doesn't perform, it's not worth owning. Many radar detectors are loaded with popular features, they look good on your dash and they are user friendly. Unfortunately, most of these units perform poorly at Ka-band and laser detection. Look closely at a detector's specification before your buy! Before buying a radar detector, you must discover: the distance at which it can sense a signal generated by a law enforcement device. Its ability to ignore non-law enforcement signals like those generated by garage door openers. False alerts: #1 complaint
A cheap radar detector will alert you to everything from the closest grocery store door opener, to the vehicle with a cheap radar detector. Many users of radar detectors complain about false alerts occurring when driving in urban areas. Since most speed traps are confined to short-range catches, this is an acceptable compromise. To maintain range, the best detectors (like the Escort 9500ix, Escort 8500 X50, Bel RX65, Bel STi, Valentine One and Escort 9500ci use specialized software to interpret and reject false alerts. If you want the most from a radar detector, these are the units to buy. (Note: Review a radar detector's City Mode specifications. Ineffective radar detectors will have half the range as their superior competitors.) Ka-Band Sensitivity a must!
Today approximately 65% of all new radar guns sales are Ka band, 15% K band and 5% X band. As this is the most difficult band for radar detectors to detect, cheaper radar detectors (and even some more expensive models) do a poor job at detecting this band. This is because X and K-band have a much narrower bandwidth (X band is a mere 50 megahertz wide and K band is only 200 MHz wide). At 2600 MHz wide, Ka band is 1200 times broader than X band! This wider bandwidth requires a detector to spend valuable time scanning back and forth to detect. This results in lower sensitivity and less range before your detector delivers a warning. The best radar detectors made today for Ka band is the Escort 9500ix, the Escort 8500 X50, the Bel STi, the Bel RX65, the Bel STI-r, the 9500ci, the Bel GX65 and the Valentine One.
