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,
VECTOR 990
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”.
VECTOR 990
incorporate 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.
