GSSI is required to notify customers of the following restrictions. However, GSSI and other GPR
manufacturers have challenged these regulations.
This device complies with part 15 of the FCC Rules:
Operation is subject to the following conditions:
1. This device many not cause harmful interference, and
2. This device must accept any interference received, Including interference that may cause undesired
operation
Warning:
Changes or modifications to this unit not expressly approved by the party responsible for
compliance could void the user’s authority to operate the equipment.
Operation of this device is restricted to law enforcement, fire and rescue officials, scientific
research institutes, commercial mining companies, and construction companies. Operation by
any other party is a violation of 47 U.S.C. § 301 and could subject the operator to serious legal
penalties.
Coordination Requirements.
(a) UWB imaging systems require coordination through the FCC before the equipment may be
used. The operator shall comply with any constraints on equipment usage resulting from this coordination.
(b) The users of UWB imaging devices shall supply detailed operational areas to the FCC Office of
Engineering and Technology who shall coordinate this information with the Federal Government through the
National Telecommunications and Information Administration. The information provided by the UWB operator
shall include the name, address and other pertinent contact information of the user, the desired geographical
area of operation, and the FCC ID number and other nomenclature of the UWB device. This material shall be
submitted to the following address:
Frequency Coordination Branch., OET
Federal Communications Commission
445 12th Street, SW
Washington, D.C. 20554
ATTN: UWB Coordination
(d) Users of authorized, coordinated UWB systems may transfer them to other qualified users and
to different locations upon coordination of change of ownership or location to the FCC and coordination with
existing authorized operations.
(e) The NTIA/FCC coordination report shall include any needed constraints that apply to day-to-day
operations. Such constraints could specify prohibited areas of operations or areas located near authorized
radio stations for which additional coordination is required before operation of the UWB equipment. If
additional local coordination is required, a local coordination contact will be provided.
(f) The coordination of routine UWB operations shall not take longer than 15 business days from
the receipt of the coordination request by NTIA. Special temporary operations may be handled with an
expedited turn-around time when circumstances warrant. The operation of UWB systems in emergency
situations involving the safety of life or property may occur without coordination provided a notification
procedure, similar to that contained in CFR47 Section 2.405(a)-(e), is followed by the UWB equipment user.

Model 5106 Antenna
The Model 5106 antenna has greatly improved resolution performance over previous GSSI midfrequency antennas, such as the Model 3105 (300 MHz). The Model 5106 can be used in continuous,
survey wheel or static stacking modes.
The Model 5106 can only be used with a “deadman” switch with the SIR-20 or SIR-3000 control
units.. These systems are designed to drive the antenna at its maximum rated pulse repetition frequency
of 100 KHz.
System Setup - Standard Settings
Shallow Profiling: Range/Depth is approximately 7m assuming a dielectric constant of 9.
Setup Mode: Manual
System Run Mode: Survey Wheel (recommended) or Continuous
Range:150 ns
Number of Gain Points: 5
Vertical Low Pass Filter: 400 MHz
Vertical High Pass Filter: 30 MHz
Samples per Scan: 512
Bits per Sample: 16
Scans per Second: Set to the maximum scan rate allowed by the SIR System used.
Deep Profiling: Range/Depth is approximately 15m assuming a dielectric
Setup Mode: Manual
System Run Mode: Survey Wheel (recommended) or Continuous
Range:300 ns
Number of Gain Points: 5
Vertical Low Pass Filter: 400 MHz
Vertical High Pass Filter: 30 MHz
Samples per Scan: 1024
Bits per Sample: 16
Scans per Second: Set to the maximum scan rate allowed by the SIR System used.
Signal Position
Place the antenna on the ground and use the Automatic Signal Position selection. The system will servo
and place the direct coupling pulse at the top of the time range window.
Manual MN30-191 Rev -
To test that you have the correct position, raise the antenna off the ground and you will observe on your
system that the antenna transmit pulse will separate from the reflection from the ground. The higher that
you raise the antenna, the further apart will be the two pulses.
To assure that the direct coupling pulse (time zero) is recorded the user should place the signal Position
servo in the manual mode. The signal should then be moved down in the time range window until the
entire surface pulse is visible and there is some ‘dead time’ or flat trace visible above the direct coupling
pulse in the time range window.
Gain Check
The surface pulse should be about 2/3 the width of the screen. If it is greater, reduce the Gains
manually. If the signal appears too small you can manually increase the Gains, but the first gain point
should never exceed 10dB, the last gain point should not exceed 65dB.
Marker/Kill Switch
A special marker switch is used with the 5106. It has a deadman switch and a separate marker button.
The FCC requires that when the operator stops interacting with the system for ten seconds, the
transmitter is to be shut off. This will also close the data file that you have been acquiring. Thus you will
need to keep the red “kill” switch on the handle depressed at all times. Releasing the handle for 2 - 10
seconds pauses data collection. Data collection that is in pause mode can be restarted by momentarily
pressing the marker button. Markers are added to the data by pressing the button on the end of the
handle, or by quickly releasing and depressing the kill switch.
