Replacing External Antenna in Radio MicrophoneRadio microphone is a type of microphone with integrated transmitter. It is a radio device with simplex communication. The operating principle of the radio microphone is to transmit modulated audio signal over the air to a receiver at a certain frequency. The range of models of radio microphones is quite wide. Each model has certain characteristics and certain areas of acoustic sensitivity. Many things depend on the microphone's transmitting antenna, its structural features, besides, most of them are external. External antenna is a segment of a conductor connected to the input of the transmitting device. Typically, the antenna's lead-in is securely fixed with plastic or rubber seal in the body of the microphone itself, thus preventing it from external influences. But sometimes even this does not prevent the antenna from damage. Frequent breaks and bends at its base lead to antenna's faults and failures, which sometimes can not be eliminated. But we are smart enough to find a way to create a new antenna. Here is one of the possible methods. First, dismantle the old antenna. To build a new antenna we will use a cable wire or a spring section. Straighten the last spring coil (about 10 mm) to weld it to the PCB of the transmitter. With the help of solder acid we solder the lead-out. Now, the protective cover. Here we use a shrink tube to protect the metal surface of the spring, as well as to isolate the lead-in. In the same way we put the antenna's lead-in into the tube making several layers to provide braking engagement with the body. Everything is quite simple and well done. Check the complete assembly when connecting.
