Gekko-80 gets to the deeper layers with the Geo-80 configuration.
The Gekko antennas are easily mounted on a standard SVC-820 4-wheel survey cart.
Airborne Antennas / Gekko-series
Overview
The antennas from the Gekko series are compact, lightweight, ultra-wide band ground penetrating antennas from the VHF radio frequency band. They have an improved signal to noise ratio and more precise resolution compared to similar devices from other manufacturers. Gekko antennas are therefore excellent for applications where deep penetration, good resolution and maneuverable GPR systems are desirable. All Gekko antennas can be used upon their arrival, and are equipped with our top of the line TR-501 transceiver. There are different plug-in combinations that can be chosen if you wish to use the Gekko antennas in bistatic mode. One possible combination is to use a RX-501 receiver with a VHT-501 transmitter. It is also possible to combine a TR-501 transceiver with a VHT-501 transmitter, allowing you to decide on site if the survey is going to be done in monostatic or bistatic mode. A great deal of time was invested in the design of the outer shell of the Gekko antennas to provide a stable construction and a degree of ruggedness that has not been achieved before. The Gekko antennas are easily mounted on the GST-806 car mount trailer, on the standard SVC-820 4-wheel cart, or on the ASH-822 hand carrier.
Applications
- Deep geology surveys
- Deep archeology surveys
- Water table mapping
- Large cavity, voids and tunnel mapping
