Understanding Radar, Laser and SWS™ k Three Radar Frequencies Three microwave frequencies have been allocated by the FCC (Federal Communications Commission) and are used for traffic Radar. They are: •X Band: 10.525 GHz •K Band: 24.150GHz •Super Wideband Ka: 33.4 GHz to 36.0 GHz Both X and K bands are well known to motorists who have traveled with Radar detectors. Introduced first was X band Radar which became common during the 1960s. In the mid 1970s the lower powered, more difficult to detect K band Radar was introduced. In 1987, FCC approval was given for Radar equipment using a third frequency, Ka. In response to this, BELTRONICS introduced the first Radar detectors capable of detecting X, K and Ka Band signals. In late 1990, FCC approval was given to Wideband Ka: 34.2 GHz to 35.2 GHz. Once again, BEL responded with Wideband Ka detection. Today, BEL's VECTOR SERIES detects the complete Super Wideband Ka frequency allotted for police monitoring-33.4 GHz to 36.0 GHz. k Total Tracking Laser™ (TTL™) Unlike Radar signals, which are highly reflective, Laser signals have very poor reflective characteristics. Many of today's Laser detectors do not have the high sensitivity necessary to detect Laser within a large "field of view". Your unit incorporates BEL's number one rated Laser detection. Twin Laser ports detect energy far outside the main Laser beam-including off-axis signals-providing the largest achievable 360° "field of view." The alerts provided by your unit are the same whether signals are received from the front 17 or rear.
