connecting the antenna to the source is approximately perpendicular to the plane defined by the flat
face of the DF antenna panel. Sources falling to the rear of the plane of the DF antenna panel will
produce substantially diminished antenna output. To help the user maintain proper orientation of the
DF antenna, a pulsed green Laser is integrated into the DF antenna. The Laser is mounted on the lower
flange of the DF antenna assembly. The duty cycle of the pulsed Laser increases with increasing level of
the detected signal.
General Guidelines for Good Signal Reception
The Wolfhound-PRO unit should be kept at about waist to head height from the floor, and away from
walls and obstructions for proper performance. For the same reason, keep the Wolfhound-PRO unit at
least one foot (but preferably more) away from large metal obstructions or surfaces (i.e., reflecting
metal walls, heavy steel structural elements, metal-wire screens, etc.). The unit should not be used
while its antenna (either kind) is contained by bags or enclosures made of metal, carbon or other RF
energy absorbing or shielding materials; doing so will seriously degrade its performance. These criteria
are listed in Table 2 below:
Table 1. General Criteria for Good Signal Reception
Keep unit away from large conducting surfaces which tend to short out tangential
component of electric fields (this includes the human body).
The unit should have 360 degree unobstructed view in the region of space being
monitored.
Avoid enclosing unit in other objects, in particular objects with conducting or
energy dissipating surfaces
Monitoring Cell Phone Use in Real-Time
For real-time monitoring of cell phone use, observe the Coarse and Sensitive bar charts in the OLED
Monitoring screen ( see arrows (2), (5) in Figure 4).
Monitoring Coarse Scale Maximum Hold
The Coarse Scale Maximum Hold marker ( see arrows 1 in Figure 7, 8 or 14) represents the maximum
observed level of the detector output signal since the last re-set of the Coarse Scale Maximum Hold
marker register. The Coarse Scale Maximum Hold register can be re-set to the noise level at any time
while in the OLED Monitoring screen, by pressing the “-↓-” button (arrow 8 in Figures 7, 8 and 14).
Using Wolfhound-PRO Unit with the Omnidirectional Antenna
To detect and monitor the existence of powered-on cell phones in a confined space, place the
Wolfhound-PRO unit at about waist to head height from the floor, away from walls and obstructions.
