At present, one of the urgent scientific and technical problems in the field of radio communications is the organization of tactically flexible field communications from unprepared areas. The solution to this problem can be the creation of HF radio complexes with rapidly deployable antenna systems in their composition. Such antenna systems could also be used as part of stationary radio complexes as backup systems deployed in the event of failure of the main antennas. At the same time, such standby rapidly deployable antenna systems should have small dimensions and short deployment time. Also, at the same time, the radiation pattern of the antenna system should have a pronounced maximum with the possibility of its operational control. At the same time, the antenna system should provide the possibility of organizing communication in the entire HF band (3-30 MHz).

To solve this problem, it is proposed to use a two-element phased antenna array consisting of antenna elements in the form of asymmetric loop Pistohlkors vibrators with a variable working length, which is achieved by using telescopic supports.

The electrodynamic analysis of the antenna system was performed using the Fredholm integral equations of the 1st and 2nd kind, supplemented by the Sommerfeld integral representations, which make it possible to take into account the influence of the semiconducting underlying surface.

The results of the study showed the feasibility of using such a solution in view of achieving acceptable electrodynamic directivity characteristics and impedance characteristics of the antenna system in almost the entire HF range.
