Regulatory Information
The use of GSSI antennas is governed by different regulatory agencies around the
world. Specific antenna models must be certified for legal operation in your country. Please
read and understand the following regulatory passages that pertain to your antenna. A listing of
certified antennas by region can be found www.geophysical.com/regulatoryinformation.htm.
Notice
Operation is subject to the following two conditions: (1) this device may not cause interference,
and (2) this device must accept any interference, including interference that may cause undesired
operation of the device.
Survey Wheels
All of GSSI’s antennas are designed to operate with survey wheels. Some antennas have built-in
survey wheels, including the 62000 Palm Antenna and the Mini-SIR. The series of concrete
antennas, including the 5100, 5101 and 52600, have survey wheels built in to their special carts,
the 614 and 615. The larger antennas, including the 3101D, 5103, 50400 and 50270s are used in
the larger carts, the 623 and 643, which have survey wheels built in to them. Various sizes of
survey wheels can also be attached directly to these antennas. This includes the 611, 620 and
622. For highway surveys we use the 630 Distance measuring Instrument (DMI).

Informations réglementaires
L'utilisation des antennes GSSI est régie par différents organismes de réglementation à travers le
monde. Certains modèles d'antenne spécifiques doivent être certifiés pour un fonctionnement
légal dans votre pays. Merci de lire et comprendre les passages suivants de réglementation qui
s'appliquent à votre antenne. Une liste des antennes certifiées par région peut être trouvée sur

Avis
La mise en œuvre est soumise aux deux conditions suivantes: (1) cet appareil ne doit pas
provoquer d'interférences et (2) cet appareil doit accepter toute interférence, y compris les
interférences qui peuvent causer un fonctionnement non désiré de l'appareil.
Roues codeuses – Odomètres
Toutes les antennes GSSI sont conçus pour fonctionner avec des roues codeuses. Certaines
antennes, comprenant l'antenne 62000 Palm et le Mini-SIR, intègrent directement les roues
codeuses. La série d'antennes pour le béton, comprenant les 5100, 5101 et 52600, ont des roues
codeuses intégrées à leurs chariots spéciaux, les 614 et 615. Les antennes plus grandes, telles que
la 3101D, 5103, 50400 et 5104 sont utilisées dans les chariots plus grands, les 623 et 643, qui ont
des roues codeuses intégrées. Différentes tailles de roues codeuses peuvent être également être
fixées directement sur ces antennes, comprenant les 611, 620 et 622. Pour les auscultations de
chaussées nous utilisons l’odomètre 630 (DMI : Distance Measuring Instrument).

270 MHz Antenna
The Model 50270s antenna has greatly improved resolution performance over previous GSSI
mid-frequency antennas, such as the Model 3105 (300 MHz). The Model 50270s incorporates
GSSI’s Smart Antenna recognition technology and will identify itself to select GSSI control
unites. The Model 50270s can be used in continuous, survey wheel or static stacking modes.
The Model 50270s has a center frequency of 270 MHz when measured in air.

270 MHz Antenna
Model 50270s
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.
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.
Specifications
Center frequency: 270 MHz
Pulse duration: 3.6 ns
Depth of penetration: 0-25 ft depending on dielectric permittivity
Size of sensor: 17.5×17.5×7.5 inches (44.5×44.5×19cm)
