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).

Geophysical Survey Systems, Inc. 270 MHz Antenna Model 50270s 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. System Setup - Standard Settings Shallow Profiling: (SIR-3000 preset) Setup Mode: Manual System Run Mode: Survey Wheel (recommended) or Continuous Range: 75 ns Number of Gain Points: 3 Vertical Low Pass Filter: 700 MHz Vertical High Pass Filter: 75 MHz Samples per Scan: 512 Bits per Sample: 16 Scans per Second: Set to maximum scan rate allowed by the SIR System used.. Deep Profiling: (Recommend manual setup) Setup Mode: Manual System Run Mode: Survey Wheel (recommended) or Continuous Range: 175 ns Number of Gain Points: 5 Vertical Low Pass Filter: 700 MHz Vertical High Pass Filter: 75 MHz Samples per Scan: 1024 Bits per Sample: 16 Scans per Second: Set to maximum scan rate allowed by the SIR System used.

Geophysical Survey Systems, Inc. 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) Weight of sensor: 19 lbs (8.6 kg)
