Radar Speed Monitoring Systems
Three band frequencies have been approved by the Federal Communications
Commission (FCC) for use by speed monitoring radar equipment:
X band 10.525 GHz
K band 24.150 GHz
Ka band 33.400 – 36.00 GHz
Your detector detects signals in all three radar bands, plus Ku band (13.435
GHz), which is an approved frequency used in parts of Europe and Asia.
VG-2
VG-2 is a “detector detector” that works by detecting low-level signals emitted
by most radar detectors. Your detector does not emit signals that can be detected
by VG-2, but does detect VG-2 signals and will alert you when a device is in use
near your vehicle.
