Accessorizing your car with a premium quality car antenna confirms a seamless transmission of radio signals.

Car radio antennas are considered a piece of beneficial automotive equipment as they contribute to the transmission of wireless signals and radio waves.

Car radio antennas are all over the automobile stores, but that doesn’t decrease their price.

If you want to be consistent on a budget and still get the radio-like experience, we’ve found the perfect solution!

Yes, car radio antennas can be a DIY job. We will cover the basics of radio car antennas as well as tell you all the secrets to a DIY car antenna.

Can a Radio Work Without an Antenna?

In just about all cases, the radio will have a receiver that does not have an antenna attached to it

The strongest signals will be received by this receiver, however, they may be susceptible to interference. In addition, the signal can fluctuate from time to time.

Using a basic antenna, you can stabilize the strong station signals.

There are many ways to how you can make your radio work without any antenna, but still, these ways are recommended only and only if you don’t get access to any radio antennas or get the equipment for a DIY.

Such as using Bluetooth, USB, analog cables, or even by getting an FM transmitter.

But since this is not today’s topic, we won’t bother emphasizing it and straight get to work.

How can you make a better FM antenna at home?

With items found easily at home, DIY antennas can’t be any big deal to make.

you just need to follow safety protocols so that you won’t hurt yourself while cutting and adjusting the wires.

Just like your car’s manufacturer, it is only you who knows your car very well.

So, it won’t be any problem when you go through this DIY project and adjust the lengths, find the best reception spot and also keep in regular maintenance.

Recapitalizing all these points, a DIY car radio antenna will be almost a free setup, will avail you to get access to strong radio stations, and will also be your go-to process whenever you need a replacement.

Benefits of a good car radio antenna

Be it a stock radio antenna, or a DIY radio antenna, if they are of good quality, you are ought to get the best results.

Before we start talking about this interesting method of DIY, we think it will be better to look at the importance of car radio antennas.

That way you will be more informed and engaged!

Antennas come in various ranges, but they all serve the greater purpose of transmitting strong radio signals. Some of the dominating types are loop, dipole, and slot.

They, overall, provide the below-mentioned features to make them stand out. (Both DIY ones and stock ones)

  • Some are inexpensive and still provide a good gain.
  • Good performance is achievable while being smaller in size and are not easily de-tuned by hand movements.
  • Wideband applications are possible with this technology.
  • The antenna construction is usually thin and directional.
  • The effects of environmental factors are less pronounced.
  • They are extremely hardy in the wild.

We guess now we got you more excited about this project, didn’t we?

How To Make A Car Radio Antenna

DIY car antenna

Before jumping on to the process we thought we would share some ideas so that you have an overview of everything.

We will go through the essentials like the necessary tools, the expenditure, required time, and then finally, a step-by-step guide.


If you are checking out today’s topic for an easy DIY to make an antenna, you might just about start working after seeing the tools list, hands down!

  • Scissors
  • Tape
  • A pole/stick
  • Wires
  • Tacks

The expenditure

We all could hear that sigh of relief when you were done with the tools! And that’s right, a DIY antenna will cost you nothing.

Just make sure every item you use on the list is not too old.

But if you decided not to give the effort of doing a DIY and instead planned on using the car radio without an antenna, the setup would cost you at least $120.

And an actual store-bought antenna would cost somewhat like $90, whereas the labor price, excluding the $90, would fall in the range of $50 to $80.

Summarizing the data, now you should get the point that how cheap a DIY can be. So buckle up, because you are in for a low-budget-premium ride!


If you have everything ready in your hand, then this project will not take you more than ten minutes.

Even if this is your first car, and you want to try out a cool DIY method, this will take you just 30 minutes as a beginner.

The only time you want to be informed about is the time after the setup. As that will be your radio-frequency-spot hunt!

Take enough time to find the spot where you think the DIY antenna catches more signals for your car radio.

Also, you might have to find a suitable spot and take the necessary steps accordingly where your antenna won’t just fly away in extreme weather conditions.

A Step By Step Guide on How To Make a DIY Car Antenna Radio

We bet after seeing this easy guidance you will make your first ever car radio DIY antenna and start installing it into the car and listening to stations in no time.

Safety protocols:

You will be working with scissors and wires so don’t make haste. Work gently. Remember, ‘Easy does the work.’

Step 1: Prepare the tapes

Get a tape pack. It is recommended to use strong adhesive tapes such as Scotch’s extreme mountain tapes as they can adhere to almost any surface.

Cut the tapes into long trips. Make them 3-4 inches long. Keep them aside as you’ll need them later and get to the next step.

Step 2: Cut the wires

This is a trust-the-process step and also the most crucial one.

Cut the wires to the length where they will be reachable to the stereo system.

But don’t get the exact length. You have to use some extra to be worked with later. Keep a foot or two aside from the exact length and then cut as a whole.

Step 3: Strip off the rubber insulation

After you are being done with the cutting process, it’s time to strip off some insulations.

Wires are covered with rubber insulation (mostly black) to prevent the metal part from being exposed. We will be working with those metal parts.

Strip off parts of the insulators from each end of the wire. Don’t do it much. About half an inch or an inch from both sides.

Step 4: Time for twisting!

Remember the pole? Get that and twist the exposed metal of the extra-kept wire at one end of the pole. Swirl it, oscillate it, make it as tightened around as you can.

Step 5: Wrap the pole

Done with twisting? Now, it’s time for you to cover the entire pole surface with the same wire.

This time, you won’t have to put pressure and get everything covered like the previous step.

Just wrap up as much area as possible. The structure, in the end, will look like a single-helix DNA strand.

After you get down at almost the end, put a tape around the wire and stick it to the pole tightly.

Don’t finish up the wire. Remember, we are only done with one side of the pole. Time to get to the other side.

Step 6: Repeat

Twist the exposed metal around, again (on the other end of the pole with the same wire). Tighten it!

Note that, if you have trouble even while working with the exposed metal sticking to the pole ends, you can use the tape

You should have some wire left. Like you did with the other side, wrap it around the pole and stick it with the tape.

And that’s why we told you to keep that extra wire so that you could work with the pole.

Now time for installation.

Step 7: Insert

Look for the FM wire slots/inputs. Normally, they are placed at the back of your radio.

Plug that wire in.

Step 8: Tacking

Affix a couple of tacks to your wall. Spread them about ten inches vertically and weave the wire around the tacks.

Step 9: Check

This is the most exciting part, the moment of truth!

Test the antenna you just made and look up to stations.

We hope it works!

If that doesn’t work, you can do these:

  1. Check if all the tapes you put around the pole are stuck strongly.
  2. Investigate if that’s the place where you ought to get good reception.
  3. If all these don’t work, give it a last try by stripping off more insulations than you did last time.

Common Problems of Radio Antenna

Antennas can be easy to work with, but they can also give you headaches.

Whether you work with one hand-made or store-bought, they will make you face almost universal problems!

If you know these problems before dealing with antennas, it will be much easier to work with and you will also know what to do when you have problems with your own.

Broken tuner

When the CD player is working but the antenna is not.

Probably the tuner or the antenna is broken when you can only listen to CDs. If there’s no tuner, it’s a new head unit!

Car radio antenna damage is common. Tube kinks cause issues. Might also happen when the radio’s rope breaks.

As a solution, clean and re-signal the antenna. Examine and repair the trunk trim if the problem doesn’t go away.

Malfunction of amplifiers

Amplifiers are very popular among owners and drivers who want to amp up their CD player and radio system experience.

They need a continuous voltage for well-functioning.

This implies any problem in the battery/alternator of the car will lead to the malfunctioning of the car radio, eventually, it will affect the car radio antenna.

Improper mounting

Whether or not you have access to tools, almost all common antenna problems are a direct result of improper antenna installation.

Trunk lip mounts are a good example because they put a lot of strain on both the antenna and the mount when the trunk is opened and closed.

As a result, the set screws that hold them in place become increasingly loose with each operation.

Frequently Asked Questions of How To Make A Car Radio Antenna

The topic will remain incomplete if we don’t give attention to details, which are the questions we assumed you would ask.

These FAQs will give the beginners the full confidence of performing a DIY on their own as well as broaden the vision of the experts.

Which configuration I should keep as a reference while making a DIY car radio antenna?

A dipole antenna. It is the go-to solution for receiving VHF FM broadcasts.

If I don’t want to go through the troubles of antenna, both stock and DIY, what other options do I have left?

TV antennas. They work just as like because the transmissions are pretty close.

Outdoor antennas are recommended for this case but you can also go for an indoor one.

What can I do to extend my DIY car radio antenna?

Simply cover the antenna with aluminum foil that will cover the signals better.

Also, try to move the antennas in different directions as that might catch up the best reception for your radio.

What if my stereo has separate AM/FM inputs?

Take the end of the antenna wire that connects to the stereo, twist on positives and negatives (both with 2) with both ends with the insulators stripped off, and stick them with the tape.

And voila! You will have another set of wires to connect to both inputs with the same antenna.

With the DIY method mentioned here, to what distance can I get a decent reception?

If you connect it to the right spot, you should have clear reception 75+ miles away!


It can be hard to get hands-on brand-new factory antennas. As long as you don’t have it, don’t hesitate to check this through and give it a try.

An antenna for the car radio is always recommended for better signal receptions and the well-being of AM/FM ports.

This will not only be a way to entertain yourself while you slave away in a long drive, but it will also give you rid of fluctuations of an antenna-less radio.
