S.H.A.D.O.
Mk.4B R.F. BUG Detector

The S.H.A.D.O. Mk.4B R.F. (Radio Frequency) Bug Detection Meter was most recently employed - extremely successfully - to track down bugging devices (two audio transmitters and three miniature cameras) placed in Colonel Paul Foster's apartment. The bugging devices were activated when the light switch in one corner of Colonel Foster's living room was switched on.

S.H.A.D.O. Mk.4B R.F. Bug Detector

The new and upgraded WE4B S.H.A.D.O. R.F Bug Detector is an instrument used to detect hidden bugs using the broad band radio frequency spectrum. The RF receiver has a range from 5MHz to 6.4GHz. A matched antenna is used to detect any RF waves transmitted by hidden R.F. Bugs (Transmitters) used for eavesdropping purposes. The receiver has the capability of handling different band signals with separate antenna inputs, (an external antenna may be connected with main RF tuner input circuit or UP converter or with down converters) the signals received are processed for detecting the presence of any bug signal. The signal frequency and its strength are initially displayed by the standard top panel meter (nb: on the underside, a hidden panel can display further information: i.e. the actual signal strength measurement is displayed in real time by an LED bar graph and other signal characteristics).

The WE4B is able to detect all types of transmissions including NBFM, WBFM, AM, FM, burst transmitter and
video transmitter etc. having signal strengths better than -70dbm. The signals are recorded in real time and available for download for later analysis.

 The WE4B S.H.A.D.O. Detection Meter


The WE4B S.H.A.D.O. R.F Bug Detector has been carefully designed with cooperation from specialist members of the Harlington-Straker Photographic Department, and unless under very close scrutiny the WE4B displays all the usual characteristics of an industry standard photographic light meter.

FEATURES

1. Rapid detection and location of electronic surveillance devices.
2. Ease of operation, highly effective even with limited training.
3. Silent cover detection and location, “gives you the real advantage over adversaries”.
4. High R.F sensitivity can locate a bug as low as 1 microwatt.
5. Total spectrum coverage from 5 MHz to cover 6.4 GHz
6. “LED Compressed” bar graph covers 20 points.
7. Demodulated audio gain is adjustable.
8. For quick & accurate scanning of frequency spectrum the step size can be selected (50 Khz, 100KHz, 500KHz, 1MHz, 10MHz and 100MHz).
