In areas of high RF activity, such as big cities, interference can make it difficult to
pinpoint local active RF transmitters. When time is short and high-level emergency
or external meetings are required it is essential to be able to quickly and easily
locate active radio eavesdropping devices.
HSS- VDR is a handheld differential RF
field-strength wide band detector. Rather
than measuring the absolute field
strength, HSS- VDR measures the rate of
change in field strength. Ideal for use in
areas with high RF activity, this technique
provides a high degree of rejection of
strong distant signal sources, providing
greater discrimination against outside
signals. The result is accurate location of
active radio listening devices, wherever
the meeting.
A Push Button is provided to reduce the
sensitivity of HSS- VDR whilst working
close to a local transmitter. This prevents
a maximum response occurring too far
from a transmitter to locate the source
accurately. Portable, quick and simple to
use, HSS- VDR is the ideal tool for quick
location of
active listening devices.
User Benefits
• Measures the rate of change in
field strength, allowing active
transmitters to be easily identified
in areas with high RF activity
• Push-button sensitivity reduction to
allow more accurate pinpointing of
active transmitters
• Easy to operate for non-technical
users
• Silent Operation option so that
detection can be as discreet as the
user chooses
• Highly versatile, ideal for locating
radio bugs, basic RFI/EMC testing
and localizing illegal high-power
broadcast transmitters
