Three Radar Frequencies Three microwave frequencies have been allocated by the  (Federal Communications Commission) and are used for traffic Radar. They are: X band z K band z Super Wideband Ka z to z 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 s. In the mid s the lower powered, more difficult to detect K band Radar was introduced. In approval was given for Radar equipment using a third frequency, Ka. In response to this introduced the first Radar detectors capable of detecting X, K and Ka band signals. In late approval was given to Wideband Ka z to z. Once again,  responded with Wideband Ka detection. Today Cordless detects the complete Super Wideband Ka frequency allotted for police monitoring-. to z. 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 Cordless incorporates '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 eld of view". The alerts received by your unit are the same whether they are received from the front or rear. Note-the use of the pocket reflector will provide front Laser detection only.
