DIY Tips On How To Replace A Broken Antenna

Radio antennas are just as important as the radio. They capture signals from transmitters for the radio to broadcast. Without the antenna, you’ll have a useless radio.

Regardless, antennas are not as sturdy as the other parts of the radio. They’re fragile materials prone to bending and breakage. But antenna damage doesn’t signal the end for your radio. 

You can replace a damaged antenna and get your radio working again. This article will show you how to replace a broken radio antenna.

How To Replace A Broken Radio Antenna

Required tools

First, you’ll need some tools. Get the following tools: pliers, a screwdriver, a universal antenna wrench, a clean cloth, a crescent wrench, an electrical tape, and of course, the replacement antenna. 

If you don’t know what a crescent wrench is, a crescent-shaped (hence the name) is an adjustable spanner. It includes an adjustable screw in the head for twisting bolts and nuts of specific sizes.

Steps To Replace A Broken Antenna

So, let’s walk through the process of replacing your antenna and get your radio buzzing again.

Identify your antenna:

To replace an antenna, you must first identify the type. Depending on the type, the setup and wires vary. Antennas may be internal, exterior, and satellite antennas. 

Internal antennas have more protection from damage and the weather. Installing and uninstalling them can influence your car’s reception.

External radio antennas mount securely on the hood of your car. They have stronger reception than internal antennas but are more susceptible to weather damage or breaking. 

Satellite antennas are common in cars. They have a radio dock mounted in the dashboard or near the windshield.

Detach the connection cables:

Find the cable that connects the radio antenna to the radio dock behind the dashboard. This cable may be a coaxial cable or an extension cable.

A coaxial cable is a single continuous cable. You can unhook it from the rear of the radio. You’ll first need to reposition the equipment for convenient access to the connection. 

Apply penetrating oil to the exposed thread entering the jammed F-connector. For extension cables, unhook them at the extension coupler. 

To loosen the nut, turn the wrench clockwise. Add extra penetrating oil to the joint if the nut doesn’t budge. After re-oiling, use the wrench to release the nut. Loosen the nut and unplug the coaxial cable.

Remove the rubber gourmet:

A rubber grommet is a seal that keeps water, dirt, and debris away from your radio antenna. Using a clean cloth, clean the area surrounding the antenna before removing the rubber grommet. 

If the rubber grommet is on the outside of your car radio, remove it with a flathead screwdriver. If the gourmet is inside, wires may be passing through it. So, instead of a screwdriver, cut the rubber grommet using a razor blade. Be careful not to cut the cables enclosed in the gourmet.

Unscrew the antenna:

Unscrew the antenna to remove it. You’ll usually find it under the dashboard on the front passenger side. To remove the nuts at the mast’s base, use a wrench, pliers, or a screwdriver.

After removing the screws, pull the mount from the car’s surface and peek under the dashboard to see the exact position where your antenna mounts to the vehicle.

Release the sockets:

After removing the screws and nuts, remove the socket using a crescent wrench. This step prevents the socket from falling to the ground or damaging your car’s paint. After removing the socket, wipe the automobile with a clean cloth.

Remove the damaged antenna:

You can now remove the damaged antenna. Remove the coaxial cable socket and then the antenna. To do this, pull the coaxial cable through the vehicle’s frame hole.

Remove the antenna gently from the surface to avoid damaging the paint. Keep the socket and all the screws in a box so you can use them to install a new car radio antenna.

Mount the new antenna:

Reverse the steps used to remove the old radio antenna to install a new one. Install the new antenna in the space left by the old one. If your antenna is on the roof of your car, use a coaxial wire to connect it to the radio dock.

Attach the radio antenna socket to the frame of the vehicle. After connecting the coaxial wire, add a rubber grommet to shield the radio antenna from water, dirt, and debris. Tighten all of the antenna’s nuts and screws using a wrench after installing the socket.

How To Fix A Broken Radio Antenna

Sometimes, your broken radio antenna may be fixable. With a few hacks, you can get it to work again. Replacing a broken radio antenna is possible in two ways: using aluminum foil or a soda can.

Using aluminum foil

Follow the steps below to use aluminum foil to repair a broken radio antenna.

  • Check your antenna for any issues. Many radio antennas have telescoping links that you can extend or retract. The link under your antenna’s break is a great place to use aluminum foil.
  • Make a single sheet of aluminum foil. The signal can’t pass through gaps in the metal, so you must use a single piece of unbroken foil.
  • Reattach the antenna’s shattered part with foil. Wrap your foil around the fractured bottom of your antenna’s upper half. Aluminum foil is malleable, so your antenna will be fragile unless you apply duct tape.
  • Duct tape your foil. In addition to weatherproofing your antenna, this will improve the connection between the two halves. Wrap the duct tape around the foil completely.
  • Examine the signal quality and make any changes. Check your radio to see whether the tweak improved your signal. If the signal is still weak, rewrap the antenna to close a gap in the foil.
  • Different wrapping techniques may impact the clarity of your radio reception. Because each antenna break is different, you may need to experiment with different metal wrapping procedures.

Using soda can

Follow the steps below to repair a broken radio antenna with a soda can.

  • You’ll need a pen, a notebook, scissors, needle-nose pliers, and a clean soda that can fix your broken radio antenna. You’ll also need a flat, open surface.
  • Follow the steps below to repair a broken radio antenna using this method. 
  • Make a spiral strip out of your soda can. Separate the can’t top from the rest of the can. Make a single cut that spirals down from the top of the can to the bottom at a gradual angle. Remove the bottom of the can after cutting.
  • Trim and flatten your aluminum strip. Flatten the spiral strip entirely with a flat, heavy item (such as a book) or even your hands. Remove any burrs or rough edges from your flattened strip.
  • Gather whatever shards or chunks of aluminum you may find. These are razor-sharp, and they can cause wounds or slivers.
  • Crease your strip, so the outer ends meet. To start crinkling your metal strip, run your pen over the middle of it. Bend the outside edges of the strip, drawing each side together over the fold. As a result, your aluminum will be cylindrical.
  • Connect your antenna to the antenna port or the unbroken end. Fold the outside edges around the remaining nub if your antenna has broken off at the bottom. If the antenna breaks higher up, wrap the outer corners around the metal extension to stabilize it.
  • It’s possible to narrow your aluminum to fit in the antenna receiving hole, but if the port is broken, you’ll need to replace the entire antenna assembly.
  • Stabilize as needed. If your antenna is long enough, you can wrap it with your cylinder foil. This action may lead to a stable junction. Use duct or electrical tape to brace your antenna if it’s fragile or exposed to the elements (wind should be a significant worry).

About Antennas

Antennas are considerably more than mere radio accessories. They transform a transmitter’s voltage into a radio signal. They also collect radio signals and convert them to voltage for reception in a receiver.

There are various reasons we need antennas, but one of the most essential is that they allow us to send signals (or data) when other techniques cannot. So how do antennas work? Continue reading.

How Antennas Work

The transmitter’s antenna generates radio waves. The antenna receives a voltage at the desired frequency—the antenna elements’ voltage and current form the electric and magnetic waves. The antenna creates a small voltage at the receiver. So the antenna becomes the receiver’s input signal source.

A radio wave is a magnetic field crossed by an electric field. Both oscillate at the same frequency and travel perpendicular to both areas at the speed of light. They support and regenerate each other, but distance weakens them.


Radio functionality depends on its antennas. Radio antennas receive signals from transmitters. Antennas are not as strong as the rest of the radio’s components. They are delicate materials that are prone to bending and breaking. 

However, antenna damage does not necessarily mean the end of your radio. You can repair or replace a damaged antenna following the steps provided in the article. It’s also possible to fix broken antennas depending on the level of damage.
