300 MHz antenna unit, shielded, surface coupled


  • Input power: 0.35 A @ 12 V DC by cable from control unit
  • Dimension: 94x53x13 cm
  • Weight: 13.5 kg
  • Receiver sensitivity: 120 mcV
  • Receiver gain: 10 dB
  • Transmitter output: 400 V
  • Resolution and depth: 1.0 x 7-10 m*




* 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.
