• All elements of generator work in regime of switching . It ensures the high efficiency of circuit.

• Generator has the great admissible output power.

• There is the wide range in a load resistance.

• The variables frequency of pulse ensures: identification of generator signal is very simple:

  • the work of the generator and the receiver have not a fine-tune, because the generator's signal gets in the wave band of receiver with any possible faults of tuning.
