How To Build Your Own FM Antenna Booster? However, it may also be a separate device.

In many cases, the FM antenna booster is a part of the radio reception device. A weak signal will result in choppy or inaudible sounds. Of course, your radio receiver uses an antenna (along with an antenna cable) to capture radio waves.įM antenna boosters seek to strengthen the signal before it reaches the head unit of your receiver. When your radio receiver gets the carrier wave, it extracts the audio and transfers it to the speaker(s). Nevertheless, during the broadcast, the radio station modulates the electromagnetic carrier wave to hold audio. Thus, we would not be able to have multiple radio channels. Essentially, if they disclosed signals at the same frequency, radio receivers would not distinguish between them.

All radio stations broadcast radio carrier waves in a frequency that is unique to them. To understand how the FM antenna booster works, we must realize how FM radio waves and receivers function. Effectively, this will make the FM antenna booster more efficient in boosting specified signals.Īn antenna that receives radio signals – often has a booster built into it. Thus, we must include a mechanism that weeds out unwanted calls and noise in the amplifier's design. Most FM antenna boosters amplify signals indiscriminately. Often, people also refer to FM Antenna boosters as FM amplifiers. In turn, it enables you to improve how well an FM receiver gets a radio signal. How To Build Your Own FM Antenna Booster?Īn FM antenna amplifier is a device that allows you to increase the FM signal strength emanating from an FM transmitter.
