Antenna Model 5103
Used for moderately shallow investigations and is ideally suited for utility detection, underground storage tank locating and void identification. (400 MHz)
Antenna SubEcho-40
Very High Penetration, 35 MHz Ground Probing Radar Antenna
The SubEcho-40 is a low frequency, portable lightweight antenna with very high penetration. The antenna is perfectly matched, so it does not have to be in contact with the surveyed media. Even airborne surveys can be performed with good results. One man surveys with one or two antennas are possible, even in hard terrain. The elements and electronics are all embedded in armed fiber-glass, making the antenna waterproof. The antenna is delivered with four universal fastening points and shoulder strap. Optional is two glass fiber rods for winch mounting and basic operation
