Model 62000 Palm Antenna
Thank you for purchasing the Model 62000, 2000 MHz Palm Antenna. The Palm Antenna
combines exceptionally fine resolution in a small package. Its small size will help the concrete
scanning professional to get into areas which are too tight for conventional antennas.
The Palm antenna incorporates an integrated survey wheel which can change position and allow
you to use the antenna in a cross-polarized configuration to aid in the detection of non-metallic
objects. The Palm antenna also comes with an integrated control cable with a length of 7 m
(22.75 feet). There is also an antenna safety attachment point 1.5 m (5 feet) from the antenna. If
you are working high above the ground, GSSI recommends attaching the safety point to your belt
so that the antenna will not be damaged if you drop it.
The Palm antenna is backward compatible with previous GSSI SIR Systems.
Note: The indented vertical lines on the sides of the antenna housing denote the center of the
antenna. When marking locations on the concrete, this is the reference point on the antenna to
mark.
System Setup - Standard Settings
Note: You must follow these setup instructions exactly to use the Model 62000 antenna.
Positioning of the signal will be the last step in the process.
Setup Mode: Manual
System Run Mode: Survey Wheel (recommended) or Continuous
Range: 5-8 ns
Scans/foot (meter): 90 (300)
Number of Gain Points: 4, Auto Gain
Vertical Low Pass FIR Filter: 4000 MHz
Vertical High Pass FIR Filter: 500 MHz
Vertical High Pass IIR Filter: 10 MHz
Samples per Scan: 256 or 512
Bits per Sample: 16
Scans per Second: Set to the maximum scan rate allowed by the SIR System used
“Deadman” Switch Operation (IMPORTANT!)
In order to comply with various emissions standards imposed by various governments, the Palm
antenna incorporates a “Deadman” switch which will turn off the transmitter when the operator
is not using the antenna. The Palm antenna incorporates two “Deadman” devices: the blue button
on the top of the antenna housing and the survey wheel. When neither of these is used, the
antenna will shut off after 10 seconds. It will resume instantly if the survey wheel is moved or
the button is pressed.

Geophysical Survey Systems, Inc. Model 62000 Palm Antenna
System Settings and User Notes
You must hold down the Blue button whenever the SIR-3000 System is doing the following:
1. Booting from the initial logo screen into your chosen data collection application
(TerraSIRch, ConcreteScan, Quick3D)
2. Changing any collection parameter (Depth, Range, Filters, Position, Dielectric, Sampling
Density, Gains).
If the “Deadman” switch is not held down during any of the above, your screen will look like the
image below. If that happens, hold down your “Deadman” switch and change your Range/Depth.
The antenna will re-initialize and you should see horizontal bands scrolling across the screen.
This process may take several seconds.
Figure 1: “Deadman” switch not held down, transmitter turned off.
Once you begin to collect data, the survey wheel will act as the “Deadman” switch. You can let
go of the blue button and as long as the wheel is turning, the transmitter will stay on.
Signal Position
1. Place the antenna on the concrete floor and use the Automatic Signal Position selection.
• If you are in ConcreteScan, this is done by pressing the Run/Stop button twice.
• If you are in TerraSIRch, go to Collect>Position> and toggle from Auto to Manual and then
back to Auto.
• You may need to try this 2 to 3 times to get the system to lock on to the surface pulse. If
after 3 tries the surface reflection is not in the signal window, point the antenna into the air
and again try the Automatic Position.
2. 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 waveform will separate from the
MN31-290 Rev - 2

System Settings and User Notes
reflection from the ground. The higher that you raise the antenna, the further apart will be
the two waveforms.
Gain Check
GSSI recommends allowing the SIR System to automatically set gain levels. Place the antenna in
contact with the concrete so that the SIR System sets values which are appropriate for the
material. Be sure to hold down the “Deadman” switch while re-initializing the gains.
The Marker Switch
The black button on the top of the antenna housing is a remote marker switch. Pushing this while
collecting data will put a user mark in the data. This is useful for situations when you want to
record the location of a surface feature or other important item in the data.
Integrated Survey Wheel
Your Palm antenna incorporates a survey wheel for collecting data in Distance (Survey Wheel)
mode. While it is still possible to collect Continuous (Time based) data with the Palm antenna,
the survey wheel cannot be removed from the antenna.
GSSI recommend calibrating the survey wheel by following the instructions presented in your
SIR-System manual. For convenience the calibration value is approximately 1697 counts/foot
(5568/m). Note that this value is subject to change and you should calibrate your own survey
wheel for accuracy.
The survey wheel can be moved to the side of the antenna in order to collect data with the
antenna elements in the cross-polarized configuration. Please see the GSSI Handbook for
RADAR Inspection of Concrete for a discussion of the benefits of this technique.
To change the wheel position
1.
Remove the three thumb screws (blue enclosures in Figure 2) securing the survey wheel
attachment plate.

2. Lift the gray, plastic survey wheel attachment plate off of the antenna and set aside
(Figure 3).
Figure 3: Remove attachment plate.
3. Swing the encoder wheel assembly to one side of the antenna (Figure 4). The side you
choose has no effect on the data.

4. Secure the wheel assembly to the antenna by screwing the attachment plate back to the
antenna. Note that the two tabs on the encoder wheel assembly will need to go into the two
cutouts on the attachment plate. (Figure 5).
