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. If they disclosed signals at the same frequency, radio receivers would not distinguish between them. To understand how the FM antenna booster works, we must realize how FM radio waves and receivers function.Īll radio stations broadcast radio carrier waves at a frequency that is unique to them.
Thus, we must include a mechanism that weeds out unwanted calls and noise in the amplifier's design.Įffectively, 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. Most FM antenna boosters amplify signals indiscriminately. Often, people also refer to FM Antenna boosters as FM amplifiers. It lets you improve how well an FM receiver gets a radio signal. This guide will explore making an FM antenna booster to complement it.Īn FM antenna amplifier is a device that allows you to increase the FM signal strength emanating from an FM transmitter.
AM FM ANTENNA BOOSTER RADIO SHACK HOW TO
Previously, we discussed how to build a simple FM radio. The best way to fix this is to use an FM antenna booster. However, radio waves can only travel so far.Ĭonsequently, when a radio receiver is too far from the signal source, it cannot convert or interpret the data it receives from the signal correctly. Today, we leverage them to make a wide range of electronic devices possible.
Radio waves are one of the most critical discoveries in technological history.
