FIELD: electricity.
SUBSTANCE: instrument comprises a lengthy element of a well device, the first group of grooves made in the specified area in the lengthy element of the well device, the first electric conductor laid through the first group of grooves to form the first antenna having the first orientation, the second group of grooves arranged in the specified place of the lengthy element of the well device, and the second electric conductor laid through the second group of grooves to form the second antenna having the second orientation, so that substantially in one place of the element of the well device the first and second antennas with different orientation are formed. Besides, antennas are installed in one place relative to the longitudinal axis and radial axis of the well device element. Each antenna may be adapted for operation as a radiator or a receiver.
EFFECT: no necessity to account various positions of antennas when processing and interpretation of a measured signal.
