If the radio signal is a bit weak for the car antenna to receive, you will most likely experience issues with reception as the car’s head unit picks the signal up then drops it. > Also check: A summarized guide to all of your car parts & functions It will only happen if your car antenna picked the radio signal and transmits it to the head unit with the help of the antenna cable.Ĭar antenna boosters are powered units that literally boost the signal by a certain amount before it can reach the head unit The carrier wave will undergo modulation so that it will be able to carry an audio signal. This audio signal is what your head unit’s tuner strips out, amplifies, and sends to the speaker. Basically, every radio station broadcasts an electromagnetic radio “carrier” wave on a specific frequency. To better understand how the antenna signal booster works, it’s crucial that you somehow know how the FM radio works. > You might concern: 5 must-know tips if you want to avoid buying fake car parts How does it work?

More powerful local stations make for bad neighborsĪside from weak and distant radio stations, another possible cause of bad radio reception is a powerful local station. Sadly, this antenna doesn’t work pretty well, unlike old fashioned mast and whip antennas. This type of antenna also does not break the car’s silhouette.
