Car Antenna Booster Quick Installation – Step By Step Guide

In case you are wondering how to install a car antenna signal booster. Here is a step by step guide to it. Remember the installation process may vary in some models depending on the model’s engineering.

However it is most likely the same in almost all car antenna signal boosters. Let’s learn how to do it.

1. Uninstall The Car Stereo System

Firstly you have to remove the stereo system from the dashboard. To do this, remove the radio’s molding and then remove the radio. You may find it difficult to remove the whole stereo system.

Use some thin metal sheet kind of things to insert them to the sides of the radio. After pushing them in tightly, grab the radio with the metals and pull it out. If it’s still stuck you can use a twitcher or a nose plier to pull out the radio. Know more, how to remove different antennas?

2. Find The Ariel Inside And Connect It To The Antenna Booster

You will see an Aerial is connected to your radio from the back. Basically that’s the antenna cable of your car radio. Detach the aerial from the radio and connect it to the antenna booster’s one end.

3. Connect The Other End Of The Antenna Booster To The Antenna

Keep the electrical connection and sound connection as it is on the radio. Then connect the other end of the antenna booster to the input located in the side or at the back of your car radio.

4. Connect The Red Wire Of The Booster To The Ignition Wire Of The Car Stereo System

Find the ignition wire from the socket you are seeing behind your radio. Connect the ignition wire to the red wire of your antenna booster using the terminal clip connector.

At this point your antenna booster installation is complete.

5. Turn On The Key To Check If The Booster Is Working

Now turn on the keys and check if there is light in your antenna booster unit. If you can see the light turning on it means your antenna booster is installed successfully and now ready to work.

6. Check Each Station And Reinstall The Car Stereo System

Do not install the stereo back right away. First check if you are getting the stations you desired. Run a scan or check each station one by one by clicking the next arrow button on your car stereo system.

If your car radio reception is fine with your radio reception now attach the radio back to the dashboard securely.

7. Drive Around A Bit More Spaces To Be Ensured About The Reception

Once you have got the stations you may want to drive some distance to verify the results. Sometimes, antenna boosters’ reception is only when the vehicle is stopped.

But there are weak signal issues again while being on drive. Ultimately it gets you no use of installing a car radio antenna booster. So, drive around to some places with medium distance playing the radio and notice the sound quality.

How A Car Radio Antenna Booster Works?

There is a misconception about car radio antenna boosters among RV owners, it is a car radio antenna booster that can bring you all the signal from every angle.

In reality car radio antennas can only boost or amplify the weak signal only when received by the car radio antenna. If the antenna itself can’t pick up the signals, an antenna booster won’t help much.

Why would it do so? Well, to get that firstly you have to understand how a car radio antenna works.

How A Car Radio Antenna Works?

If you have even a little idea about radio frequency, you may know that broadcasting stations send these RF signals with a certain frequency.

When it reaches your car radio, the radio antenna picks up the signal and sends it to the head unit of your car radio system. Then the head unit catches the signal and delivers it to the speakers.

Suppose you delivered RF signals that aren’t strong enough by themselves. If you install a car radio antenna booster here it can help to empower it. But the radio signals should be at least strong enough so that the head unit can pick it.

Otherwise you would still get no reception or static reception.

You will install the car radio antenna booster between the antenna and the head unit. When the signal transmits to your car radio antenna, the antenna signal booster will amplify it and send it to the head unit.

Therefore you will be able to get proper radio sounds and enjoy it.

When A Radio Antenna Booster Won’t Help?

You must remember that if there is no reception of a specific channel to your car radio antenna, an antenna signal booster won’t help you. In that case you may look for a better car radio antenna system.

Wrapping Up

As you have reached the conclusion I guess you found this detailed review on the best car radio antenna booster useful. This was all about it. While you go shopping for one make sure you know what you’re getting.

Firstly check your car antenna’s condition and move on to get a car radio antenna booster then. Always make sure the model you’re buying suits your vehicle type and model.
