The invention relates to the field of radar and can be used in radio devices submarine vessels. Known antenna device described in the book "Modern Navy", publishing house "Rusich", authors David Miller and Chris Miller, 2003, p.44. In it the rotation of the antenna is carried out after surfacing with a drive. When immersed antenna with the drive falls into the hermetically sealed casing cutting underwater vessel. Operation of the actuator with the actuator control module that sets the rotation mode of the antenna. The antenna can radiate and receive electromagnetic energy. However, for raising and lowering the antenna required bulky nodes and some time, resulting in delay of the radiation and reception of the probe signals. Known antenna device described in the above mentioned book on str, it uses the same nodes as in the above source, but it also delays the radiation and reception of electromagnetic signal and increases the bulkiness of the product. Using the proposed device is reduced bulkiness without increasing the delay of the radiation and reception of electromagnetic signals. This is achieved by the introduction of the radio waves of the deep protective casing with the antenna and drive within and rigidly connected to the housing is ω cuttings having rigid connection with the drive input of which is connected through the opening in the housing of the cutting with the actuator control module.

Figure 1 and in the text the following notation:

1 - radiotransparent deep protective casing;

2 - antenna;

3 - actuator;

4 - housing cuttings;

5 - hole in the housing cuttings;

6 - unit drive control.

Thus the output of the actuator control module 6 is connected through the opening in the housing cuttings 5 drive 3, rigidly connected with the antenna 2 and the housing cuttings 4, having rigid connection with the radio waves of the deep protective cover 1.

The operation of the device is as follows. Antenna 2 (see figure 1)rigidly connected with the drive 3 inside radiotransparent deep protective casing 1, carries out the radiation and reception of electromagnetic energy. Unit drive control 6 outputs the command to the actuator 3 on the rotation of the antenna 2 in a certain mode after surfacing the boat. Antenna 2 with the drive 3 is placed above the housing cuttings 4. The drive input 3 is connected through the opening in the housing cuttings 5 with the output of the control unit of the actuator 6. In addition, the actuator 3 is rigidly connected with the housing cuttings 4. A possible embodiment, when the actuator 3 with the antenna 2 is posted below. The actuator 3 is mounted within the enlarged openings 5 and the housing also has a rigid connection with what obosom cuttings 4. In this embodiment, the height of the casing can be reduced. Electromagnetic energy passes through the radio waves of the deep protective casing 1, is rigidly connected with the housing cuttings 4. This casing 1 is designed in such a way as not to create additional braking torque when the vessel is under water. This is achieved by execution of the recesses in the casing 1, which provides sufficient flow. In addition, the casing 1 is made of a material that provides radio transparency, there is little attenuation when passing electromagnetic energy, and high strength while being underwater vessel at the limit for him depth. An example of such material is presented in the book "Arms and naval technology of Russia". - M, edition of "Military parade", 2003, str-451, where it is noted that in the electric universal remote control homing torpedo casing front portion is radio transparent to electromagnetic energy as it uses electromagnetic homing system. In addition, this case can withstand water pressure of 500 m In the proposed device creates the opportunity for reducing the bulkiness due to the lack of sites that provide raising and lowering of the antenna to compensate for the decrease in weight due to the increased weight of the transmitting nodes, increasing ewnost radiation. The device can be used in navigation and overview radars, and radio direction finders and other systems performing the transmission and reception of electromagnetic energy. Thus, the use of the device increases the efficiency of radio equipment for underwater vessels.

The antenna device consisting of the antenna and drive over the body of the logging and control unit of the actuator, with the output connected to the input of the actuator rigidly connected to the antenna, characterized in that it introduces a radiotransparent deep protective cover from the antenna and the drive inside is rigidly connected with the body of the cutting, which has a rigid connection with the drive input connected to the output of the actuator control module through the hole in the body of the cuttings.
