Claims (9)

1. Устройство радиосвязи, содержащее диод и источник напряжения, подключенный к диоду, и антенну, выполненную с возможностью перемещения в первое и второе положения, отличающееся тем, что перемещение антенны между упомянутыми положениями замыкает электрическую цепь между диодом и источником напряжения.1. A radio communication device containing a diode and a voltage source connected to the diode, and an antenna configured to move to the first and second positions, characterized in that the movement of the antenna between the above positions closes the electric circuit between the diode and the voltage source. 2. Устройство радиосвязи по п. 1, отличающееся тем, что вторым положением является убранное положение и перемещение в убранное положение замыкает электрическую цепь. 2. The radio communication device according to claim 1, characterized in that the second position is the retracted position and moving to the retracted position closes the electrical circuit. 3. Устройство радиосвязи по п. 1 или 2, отличающееся тем, что электрическую цепь между диодом и источником напряжения образует антенна. 3. The radio communication device according to claim 1 or 2, characterized in that the antenna forms an electrical circuit between the diode and the voltage source. 4. Устройство радиосвязи по п. 2 или 3, отличающееся тем, что источник напряжения ориентирован на смещение диода в прямом направлении при замыкании электрической цепи. 4. The radio communication device according to claim 2 or 3, characterized in that the voltage source is oriented towards the diode bias in the forward direction when the electrical circuit is closed. 5. Устройство радиосвязи по пп. 1 - 3 или 4, отличающееся тем, что источником напряжения служит источник напряжения постоянного тока. 5. The radio communication device according to paragraphs. 1 - 3 or 4, characterized in that the voltage source is a DC voltage source. 6. Устройство радиосвязи по любому из пп. 1-5, отличающееся тем, что содержит согласующую схему, соединенную параллельно с диодом. 6. The radio communication device according to any one of paragraphs. 1-5, characterized in that it contains a matching circuit connected in parallel with the diode. 7. Устройство радиосвязи по любому из пп. 1-6, отличающееся тем, что содержит радиосхему, соединенную параллельно с источником напряжения. 7.
