Understanding Radar, Laser and SWS ™
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 S ERIE S
detects the complete
Super Wideband Ka frequency allotted for police
monitoring–33.4 GHz to 36.0 GHz.
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
or rear.
