CB Radio SWR Meter

We are living in a technologically evolved world currently which includes devices such as smartphones that come with a top performance internet connection as well as inbuilt GPS. However, there are times when you will find yourself in a remote area where the mobile phone network and internet connection is a major challenge. This is where a CB radio comes in handy.

To ensure optimal performance of your CB radio, you will be required to tune it from time to time. The most effective way of doing this is by using an SWR meter.

Most people ignore the use of SWR Meters. They believe buying the most powerful CB radio on the market and the best CB antenna is enough. Turns out, this is a huge misconception.

In order to be in a position to tune your radio, the starting point would be getting your hands on a top-notch quality SWR Meter.

Tuning your antenna, or basically adjusting the SWR (Standing Wave Ratio) is all about adjusting the antenna in order to get the right length required for transmission. Failure to do so can lead to total damage to your radio.

Here are some reasons as to why you need to get yourself an SWR meter for your CB radio.

  • With a quality SWR meter, you are in a position to get that perfect signal from your HAM or CB radio
  • It is a good indicator of the standing wave ratio level
  • With a good SWR Meter, you can get to align communication channels perfectly
  • They come with ease of use
  • They allow you to reduce or completely do away with interference
  • Before any damage to your radio, whether minor or serious, an SWR meter alerts you of any performance issues.

 How to buy a Quality CB SWR Meter

how to buy SWR meter for CB radios

SWR Meters basically perform the same function but they all come in various sizes and shapes. As such, one cannot help but ask themselves how to find the best SWR Meter for their specific needs. To make the decision easier, there are a couple of aspects that you will need to look at.

Choosing your perfect CB radio goes way beyond price. Before you settle on any SWR meter, here are some things that you might need to consider to make the decision much easier.

  • Sensitivity– This is quite an important factor to consider. A good SWR meter should not be overly sensitive, as high sensitivity can damage the transmitter.
  • Frequency range– SWR meters all have different frequency ranges. You need to ensure that the range in a given SWR meter is what your radio requires. An SWR meter that is out of range means that it is not sensitive enough.
  • Connectors– Good quality connectors see to it that you get accurate readings. Ensure that the SWR meter has connectors for both the antenna and transmitter.
  • VSWR vs SWR– Confusing as they may seem, these two mean the same thing. For both, the voltage waves and standing currents are set.


What is SWR?

It stands for standard Wave Ratio; a measure of your antenna’s efficiency in transmitting a radio’s signal, usually expressed as a ratio.

What do I need in order to tune my antenna?

Simple; just a short jumper cable and an SWR meter, both of which are inexpensive.

Can you tune a CB antenna without using an SWR meter?

Many people believe that the only way of tuning your CB antenna successfully is by use of an SWR meter. While it is crucial to use one, it is actually possible to tune your antenna without an SWR meter.

What can be said to be a bad SWR?

To answer this, you need to consider the ratio you get on the readings. Basically, the lower the difference you get, the better the SWR. For instance, if you get 1:1, things are very good. On the other hand, if you get something like 6:1, then things are terribly bad.

What do you need in order to tune my antenna?

Simple; just a short jumper cable and an SWR meter, both of which are inexpensive.

How do I go about using an SWR Meter to tune my CB antenna?

Using an SWR Meter is not a complicated thing at all. You are only required to follow a few simple steps.

What does return loss refer to?

Return loss basically indicates that the signal has lost its power. It is shown by a break in the transmission line. Usually, it is expressed in decibels.

It indicates just how much power has been transferred to the load. If all of it has been transferred, the return loss is infinite. In order to measure the return loss, you will have to use an SWR meter that has feeders or transmission lines.

What causes high SWR?

The most common cause of high SWR is any issues with the antenna. However, there are other factors to consider when you experience high SWR. It could be anything from the antenna mount, coaxial cable, mounting location to the vehicle itself.

What is a good SWR reading?

To answer this, you need to consider the ratio you get on the readings. Basically, the lower the difference you get, the better the SWR. For instance, if you get 1:1, things are very good. On the other hand, if you get something like 6:1, then things are terribly bad.

What can be said to be a bad SWR?

Readings starting from 2.5 all the way to 3.0 indicate very poor performance which is highly likely to damage your radio.

Wrapping Up!

One of the most basic human desires is communication; we all need to keep in touch with our loved ones as well as receive vital information. There are several communication devices that man has invented, most of which have become obsolete over time in a bid to welcome new inventions. The one device that has however stood the test of time for more than half a century is CB radio. This device requires tuning from time to time for optimal performance.

Despite the fact that most people believe that you can tune a radio successfully without having to use an SWR meter, this is far from the truth. An SWR meter comes in very handy as it is a precise indication of the inconsistency existing between a given transmission line and its load. It has many benefits in addition to preventing your radio from complete damage.

There are so many SWR (standing wave ratio) meters available in the market. All these have varying features, and their prices are different too. Others measure a variety of bands including VHR and UHF frequencies. The best SWR meter for CB is dependent on several factors. As such, you need to do your research well in regards to the exact characteristics of your radio as well as an antenna.
