GPR 150-75-38 MHz antenna system dipole unshielded air coupled
150-75-38 MHz antenna system dipole unshielded air coupled
Specification:
Input power: 0.35 A @ 12 V DC by cable from control unit
Weight: 2 kg to 7 kg (depends on frequency)
Receiver sensitivity: 120 mcV
Receiver gain: 10 dB
Transmitter output: 200 V
Resolution and depth: 1-4 x 7-30 m (depends on frequency)
* Relationship between resolution and sounding depth is assumed that sounding is made in a soil whose relative dielectric permittivity is equal to 4 and specific attenuation is 1 to 2 dB/m. Depth of investigation is understood to be detection depth of a flat boundary with reflectance equal to 1. Note that these data are rather approximate and are strongly dependent on parameters of the environment sounded.
