DIY CB Antenna

Making your DIY CB antenna is not an easy process, and you have to be well informed if you want the best results. There are various aspects about CB antenna set up that you have to consider. 

So, in this guide, we take a look at all the things associated with a DIY CB antenna. 

Making your DIY CB antenna requires that you consider a few things. First, you have to consider the frequency levels that you expect from the traditional radio. Start by considering that the average wavelength of such devices averages at 27-MHz, with a distance of 17 feet. 

If you want to send and receive CB, consider getting two sections of the standing wavelength. Using resources such as dual copper wires might also be excellent for this process. Plus, insulation is also crucial for these wires, and then install them in your radio. Ensure you install them on the highest and most convenient location on your vehicle. 

Making A CB Antenna

With just a few materials and some tools, you will find it easy to make a new antenna for your radio. And the best part is that you don’t have to take a trip to the store. With the right techniques the antenna should function should work just like a store bought alternative. 

You will find it easy to customize the antenna height to suit specific communication purposes. Plus, you won’t have to ever control the antenna from any location in your car. The antenna should function optimally based on your needs and the type of car you will install it in successfully. 

CB Power 

Even the most robust CB radio on the market only requires relatively low levels of power. On average, this should be like 4 watts of power. With this power, you should find it easy to send and receive alerts from a few miles.

If you want to enhance the signal strength and quality, you have to work on the distance from which you send the messages. Furthermore, you may have to take things such as the antenna height into perspective, and the specific place you expect to mount the antenna. 

Installing your CB antenna at the right position should provide you with upto 25 miles of distance coverage. It’s a sweet deal considering that you have already struggled with a few miles already.

Materials Required 

For the body of the antenna, use an average of 60 inch long rod of non conductive material. Ensure the material is sturdy such that it can withstand exposure to issues such as heavy winds. 

More so, consider using a solid quarter inch fiberglass shaft, because it will be efficient for this process. The other suitable materials for this process would be PVC, aluminum or even wood.

For transmission, get two lengths of a small copper wire that averages at 110 inches long. Furthermore ,the additional height should be for the attachment. You might also need two small insulation eggs, which you will use to separate either section of the copper wire.

When it comes to the finishing process, get a duct tape which you shall use to wrap the antenna. The ideal length of the RG-8 coaxial should be sufficient to strengthen for the place you mounted the antenna. 

Connect the correct connector, which is usually an RP-SMA-female. You have to attach to the other section after setting up the cable to your CB radio. 


electronic tools

With the right soldering iron material, you should find it easy to set up the many different components of the CB antenna. You might also have to get a roll of electronic solder, double sided duct tape, and more – which you shall use to set the antenna in the right position.

Plus, a standard toolset is also crucial for this process. A few useful components you need include pliers, assorted clamps, screwdrivers and more. 


  • 1. Wrap an average of four inches of each wire through each end of the dual insulator eggs.
  • 2. Then, move to twist the wires, such that they provide excellent mechanical contact.
  • 3. Next is to solder each twist to produce a strong electrical circuit.
  • 4. You will also have to wrap the double sided tape around the entire structure of the antenna. Do this process on the entire vertical shaft of the antenna.
  • 5. You might need an extra set of hands to help you with this process. Start this from one section of the antenna rod, and place the copper wires on the entire structure of your antenna. Ensure that the two wires don’t get in contact.
  • 6. Then cover the rod using some duct tape, and ensure all its sections are fully covered
  • 7. Next, open one section of the RG-8 cable, and then connect the center lead wire to one section of the insulation egg using a soldering tool. Also, ensure you attach the braided silver ground wire to the remaining section.
  • 8. Finally, cover the upper section of the rod using some duct tape. However, leave an average of 5 inches of space for the mounting procedure.


The ideal place to mount the antenna would be at the top most section of the car. If convenient, consider using a metallic surface for the best results. Plus, if you have a magnetic mount, set up a ground wire from the braided silver wire of your RG-8 cable. 

Ensure that you connect it to any section in your vehicle chassis. Furthermore, there are various antenna mount types that you can find on the internet, or through electronic service providers. 

CB Antenna Tuning

While tuning is not an important aspect of making a physical antenna, it’s crucial if you want to make the most of your devices. Without the right tuning procedure, you won’t be able to find a good quality signal for your radio.

You might acquire better results if you consider using the radio in open spaces. Furthermore, resources such as an SWR meter should provide you with accurate readings.

Consider an average of 1.5:1 to be the perfect ratio for radio tuning purposes. 

Challenges in Making a DIY CB Antenna 

There are various challenges you have to consider if you want to make a DIY CB antenna. These challenges vary in relation to various factors, and you have to be cautions to ensure the best results. 

A few of these unique challenges you have to consider include:

  • Gaining access to quality materials – before you can find the right resources, ensure you conduct in-depth market research. You may have to source your products and solutions from the right services for the best results.
  • Mastering the installation steps – since making CB radio involves various intricate details, proceed with caution. You may have to work on this process for a few tries before you get it right each time.
  • Tuning the radio – for this process, you may have to install in resources such as an S.W.R meter. Plus, you may also have to gain more insight into the right techniques you can use to tune the meter to suit your needs.
  • Finding the right spot to set up your radio – you may have to tinker with the radio, and adjust it until you get the correct set up location. Doing so, should ensure you have the radio for communication and without any issue such as a compromise in signal quality.


Can You Make a CB Radio Antenna?

Yes, you can make a CB radio antenna, using DIY tools. You just need a few materials, and the right steps. With the right information you should have a CB antenna ready for use in a few minutes. Furthermore, a homemade antenna should work fine as long as you get the details right. 

How High Should a CB Base Antenna Be?
