Why are radar detectors described as dual band, tri band, wide band, or super wide band?
A. Early detectors needed only to listen for X band radar. When K band arrived, dual band models able to receive both frequencies (X and K) were required. The introduction of Ka band photo radar (34.3 GHz) led to the development of tri band models able to detect X, K, plus a small portion of Ka band. A fourth category of radar receivers called wide band, with X, K and “wide band” Ka (34.2 – 35.2 GHz) detection capabilities reached the market following the introduction of Stalker radar. And finally, in response to the BEE 36A a new generation of radar detectors were developed termed super wide band, which cover all radar guns operating on X, K or “super wide band” Ka (33.2- 36.0 GHz).
