What to Look for When Buying SWR Meter
With too many choices for SWR meters, do not choose solely based on price. To help you narrow down your choices, below are some important considerations.
The most critical thing is to pick an SWR meter compatible with the type of radio you are using. Not all SWR meters are compatible with all radios. For instance, you will find some designed specifically for CB radios. Meanwhile, others will work both for ham radios only. Some will also work with GMRS radio.
To determine compatibility, one of the first things to look at is the frequency range, which should match that of CB and ham radios. The impedance rating is equally important. Using the wrong meter can cause significant damage to the radio. The readings can also end up being unreliable.
Ham and CB radio SWR meters are useless if you cannot get accurate readings. This will result in faulty tuning and low-quality radio communication. To determine the accuracy, I recommend choosing only those from reputable brands. From those mentioned above, Astatic, Workman, and Mcbazel are some of the best brands with accurate readings. While not reviewed, a Daiwa SWR meter is also accurate.
- Ease of Use
Especially if you are a first-timer, operating an SWR meter can be confusing. Pick one with an intuitive design, making it a snap to get the readings. It should come with a detailed manual. The buttons should be in strategic positions, so they are easily accessible. Plus, the display should be easy to read.
Stay away from those made of flimsy plastic. Most of the top options have a metal housing, which will protect the internal components from wear. Even the switches should have solid construction.
You will find two types of display. Older and cheaper models often come with a manual or needle-type display. Meanwhile, newer models have digital displays. I prefer the latter because it is easier to read and often more accurate. The display should also be highly visible so you can read the information the device shows.
Lightweight and compact SWR meters are the best. Look for one that is portable enough to move around easily. Otherwise, the meter can be cumbersome to use, especially if you need to use radios outside your home.
As you decide what to buy, read reviews online and learn from the real-life experiences of other people. Take note of what they are saying about the performance of the meter, such as how easy it is to use and how accurate the readings are.
Over the years, the SWR meter will inevitably experience several problems. With a comprehensive warranty, the manufacturer got your back. They can offer free repair when necessary, which can provide you with peace of mind.
A lot of people will decide based on price. You won’t be using the meter daily, so many are not interested in splurge. You can find a lot of affordable models. Nonetheless, if you are a serious radio user, you should not mind the price, especially if it means enjoying top-notch quality and performance.
What is an SWR Meter?
SWR stands for Standing Wave Ratio. In a nutshell, an SWR meter is a device that measures a radio’s transmission signal. This is important for improving the antenna and having the best signal possible. This way, you can prevent damage to radios while also making sure of the best possible quality.
Can I Use a CB SWR Meter for Ham Radios?
No, you cannot use an SWR meter for CB radios for tuning ham radios. In the same way, you cannot use it as a 2M SWR meter or 70 MHz SWR meter, unless otherwise specified by the manufacturer. Radios have different frequency ranges, and hence, you must choose SWR meters with specific capabilities to handle the requirements of the radio you are tuning.
How to Know The Frequency Range of SWR Meter
The SWR meter frequency range will be stated by the manufacturer. It is one of the most important technical specifications to consider as it will determine how far the meter can measure. If the ham or CN frequency range does not match that of the SWR power meter, it can result in irreversible damage and inaccurate readings.
Does My SWR Meter Require a Battery?
This will depend on the type of SWR meter that you are using. For instance, if you have a passive SWR meter, then there is no power button and the readings are displayed continuously. In this case, a battery is unnecessary. Meanwhile, others will have a digital display, which is when you will need a battery.
How Long Will My SWR Last?
There is no easy way to answer this question. Inferior SWR meters can last only several weeks or months and will not deliver accurate readings. However, if you choose one from a reliable manufacturer, then you can expect it to last a long time.
To the uninitiated, the best SWR meter may seem like a useless device. Nonetheless, it is useful for optimizing your radio experience. From installing an antenna to tuning the radio, an SWR meter is useful in measuring signal strength.
While SWR meters are beneficial in many ways, they are not all the same. Avoid frustration by choosing the products mentioned above. They are not perfect, but they have top-notch features that make them stand out.
