Antennas covers frequencies from 50 MHz for deep geological surveying to up to 2500 MHz for high‐resolution investigations. Using low-frequency antennas, one can increase the depth of sounding. If high resolution scanning of the near surface section is required, though, it is advisable to use high-frequency antennas. A combination of antennas with different frequencies yields best results.

|Dual-frequency||AB-300/900||300/900||7 and 2,5||20 and 8||7,8||740x460x150||11|
|АB-250/700||250/700||8 and 3||25 and 10||7,8||740x460x150||11|
|АB-150/400||150/ 400||12 and 5||35 and 15||8||930x800x280||16,5|
All of these antennas are interchangeable, compatible with the control unit or control processing unit, with a variety of different applications.
The system includes a control unit or a control processing unit and antennas with frequencies from 50 to 2500 MHz. All of these antennas are interchangeable, compatible with the control unit or control processing unit, with a variety of different applications.
For efficient work in conditions of existing air jamming (i.e. buildings, construction, power transmission lines, etc.), a set of antennas with shielded screen receivers and transmitters, protecting against the potentially harmful effect from the top semi-sphere, are available.
The integrated multi-frequency GPR OKO-3 is designed for automated location of objects at different depths, simultaneously and in real time. This GPR combines a control unit and two antennas with the different frequencies.
Horn antennas are ideal for tasks associated with the high-speed GPR surveying of elongated objects such as motorways and railways, which require ground lift-off GPR location.
