How to Tune a CB Antenna Without an SWR Meter

Obtaining your first-ever CB radio is an experience you will never forget. It is wonderful to interact with drivers on the road. Before you begin dealing with the radio or discover its range, it is vital to set a CB radio correctly. Lots of new CB radios are created with a built-in CB radio, which is quite convenient. Built-in CB meters may be less reliable than standalone CB meters, but they are better than no CB. One thing most people probably are not aware of is that you can still tune in your CB radio without a CB meter.

Why should you set up a CB antenna?

Tuning the antenna will be essential to ensure the perfect CB radio function and the best reception. Normally, a well-adjusted antenna will receive stronger signals. You should always check that you have a VHF reading below 1.5, as a higher value will show poor performance or complete damage to your radio.

What do you need for this operation:

Because there is no question of an SWR and built-in S, you should do the following:

  • A large outdoor area (about 40 meters of clean outdoor space)
  • Second CB radio (mark a friend who will help you with this second radio)

We also guess that you already have other basic necessities, such as an antenna and a power supply.

  1. Choose the outdoor area.
  2. How to Tune a CB Antenna Without an SWR MeterTo begin with, you may go to the outdoor area, where there are very few obstacles. Outdoor areas have less interference, and this allows you to easily transmit signals.  Please make sure that you close the doors and windows of your car. Meanwhile, your friend should turn on a second CB radio a few meters away from you. It is also worth mentioning that a second CB radio must be set up before this exercise.

  3. Preparing the antenna.
  4. Choose the outdoor areaFor the first launch, you can set the antenna in order to your radio station can transmit and receive at low power levels. For this, make sure that the antenna has a plastic cover if it is normally available. Thus, adjust the antenna so that you can no longer shorten it. Eventually, it is better to start with a low SWR, as it has no destructive impact.

  5. Select a specific channel on the second radio, then set the connection.
  6. The idea here is to have both CB Radios on the same channel so you can try to establish a clear connection between the radios. Once your friend has tuned to a certain channel, you can start trying to set up a clear connection between two of them.

  7. Antenna Adjustment

If your assistant informs you that the transmission is indistinct, you can continue adjusting the screw on the CB Antenna until you receive a definite signal. By loosening the screw, you can regulate the height of the antenna. Your task will be to repeat the process until your assistant tells you that the transmission is clear. If you have no SWR meter, it is wise to regulate the height of the antenna in small increments until you get a clear signal.
