Antenna has three working frequencies: 38, 75 or 150 MHz. Changing of frequency is possible by appliing of additional dipole sections.

Remarks:

(1) -means sensitivity, limited by noise

(2) - It 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.
