Best SWR Power Meter – Buying Guide
SWR meters come in different shapes and sizes, despite the fact that all they all have the same basic function.
How can you find the best SWR meter for your needs? It’s important to buy an affordable and useful SWR meter, which will fulfill its main function, soI will try to draw your attention to the most important aspects to look for as you read our SWR meter reviews.
VSWR and SWR
Should you choose a meter with VSWR or SWR? For many people, this question is no easier than the Shakespeare’s “to be or not to be” question. The good news is that VSWR and SWR are the same thing. And is the reason is that in both cases, the standing current and voltage waves are set, the power is reflected.
This is an important aspect when choosing a SWR meter, but the absolute value of sensitivity is not defined by anyone. It is clear that a good SWR meter should not have excessively high sensitivity, because it could damage the transmitter.
Which SWR meter will you find in the store? It will be a meter with a 100 uA full scale deflection. The fact is that this is the most common value for a SWR meter and it is OK.
Be sure the connectors are good quality so you will get an accurate reading. The SWR meter must have a connector for the antenna (usually labeled ANT), as well as a TX connector for the transmitter (to be connected to the radio).
There are several types of swr power meter e.g HF, UHF, VHF, 2m 70cm swr meter, 2m swr meter etc. Each has a different frequency range. You must be sure that this range is what your equipment uses, because if you use the SWR meter out of range, it will not be sensitive enough.
Why Do You Need an SWR Meter?
The fact is that many people are deeply convinced that tuning the radio can be done successfully done without using a SWR meter. This is a big misconception.
The SWR meter is needed to measure the voltage standing wave ratio. You can use it when you tune the radio. When configured, the meter will show you the degree of inconsistency between the transmission line and its load. Plus, you can use the SWR meter to measure the effectiveness of the impedance matching effort.
It is important to use the SWR meter when you tune in a CB radio or a handheld mobile ham radio , because it will allow you to minimize or eliminate interference. An SWR power meter will help you keep the radio and antenna safe.
FAQs on SWR meter
What does an SWR meter do?
Technically, it measures the standing wave ratio (SWR) in your communications transmission line, such as in your CB radio setup. With your ham or CB radio, it tells you how much RF energy is reflected back to your transmitter, in comparison to how much RF energy you’re sending out with your radio.
Basically, it tells you how well you’ve set up your antenna for efficient transmissions and communications.
How do I use an SWR meter?
There is nothing complicated about using an SWR meter, you just need to follow a few steps:
- Use a low-power channel (or a clean channel) if you do not know the characteristics of an antenna or SWR meter;
- Your goal is to find at least one standard two-way contact, to do this, spend time listening to the signal;
- Reduce the transmitter’s output power so as not to damage the transmitter if SWR is low;
- Set the mode switch so that a constant output is set (CW, AM or FM) – it will allow you to set a steady reading;
- Set the SWR meter (switch to the Forward position) and turn the adjustment knob (or CAL) to the down position. It is important to prevent overloading the meter;
- Adjust the direct reading (using the same adjustment knob or CAL);
- Reverse the measurement and read the SWR value;
- After you receive the coefficient value, you need to stop the transmission of the signal quickly in order not to interfere with other radio stations and not to break the transmitter.
And it is important to remember: if you want to use a large number of channels, check the SWR readings for channels 1 and 40, because the values will change. And when you measure at full power, shut down the SWR meter right after that.
How do you read a SWR meter?
There’s a dial on the SWR meter ranging from 1 to 10 (and beyond). If the indicator is at the 1, then you’re transmitting 100% of your CB radio’s signal.
If you have the meter at the 3 level, then you have a 3:1 reading. This means your antenna is only transmitting ⅓ of the radio signal.
What is a good SWR reading?
Expecting a 1:1 reading may be a tad unrealistic, but in general you can be satisfied with a reading that’s less than 2:1. At 2.0 and beyond, you may want to think about improving your transmission setup. If you’re at 3:1 and beyond, then you really have problems you need to fix.
What is a bad SWR?
Ideally, you will get a 1: 1 ratio. And accordingly, the situation when you get a 2: 1 or 3: 1 ratio is not the best. It turns out that the lower the difference, the better. That is 1: 1 – very good, 2: 1 – normal, 6: 1 – everything is bad.
Can you tune a CB without a SWR meter?
In theory, you can. But it’s a hit or miss operation as you never know for sure if you’ve gotten it right.
With the SWR meter, you have a definitive measure you can work with, so you know for sure how effective your antenna is at transmitting your radio’s signals. You won’t really know without the SWR meter.
Does coax length affect SWR?
In practical terms, the coax cable length doesn’t really matter when it comes to your SWR. If it does affect the SWR, the difference will be extremely minimal.
Can you leave a SWR meter in line?
Yes, you can. In fact, many experts recommend this practice. It’s especially useful for a base operation so you can keep tabs on your transmission efficiency.
You do have to make sure that the connections are secure. This is crucial if you’re mobile, or else it can get in the way.
How do you calibrate a SWR meter?
You should calibrate your SWR meter to make sure it gives you accurate readings. It’s easy enough to do this, as many SWR power meters come with a calibration function.
When you’ve connected the SWR meter to your radio, turn on the radio and pick a channel you don’t normally use to talk. If you typically use channel 18, then pick channel 17 or 19 so you don’t mess with other people’s conversations when you do your testing.
Press the mic button on the radio, but don’t talk. Instead, turn the SWR meter’s calibration knob all the way to the right so the needle can point to CAL on the dial. Once that’s done, take off the finger from the mic button and then switch the function on the SWR meter from CAL to SWR.
Does SWR affect reception?
The short answer here is that SWR doesn’t affect how your radio setup receives signals. SWR only denotes how your radio antenna sends out signals. It’s about transmission, not reception.
Why is my SWR reading so high?
One common reason is that you may have connected your SWR incorrectly. That can give you extremely high SWR readings
However, if you did this right, then you have a problem with your antenna. It shouldn’t be mounted next to metal or glass. There may be broken wires inside the antenna. You may have insufficient ground on the antenna mount. You may also have installed your antenna stud incorrectly.
There may be a problem with the coax cable as well. There may be a short in it, or it’s been too tightly coiled so as to cause a signal feedback.
Can high SWR damage a radio?
It’s theoretically possible for your setup to reflect enough heat to your final RF transistor. The damage won’t be immediate, though, and it will be minimal if you fix the problems right away. However, over time the heat can result in damage to your radio. The de-tuned final amplifier can cause a high current or voltage problem in the final stage of the transmitter.
What is return loss?
By getting information about the SWR you can find out the “return loss”. This means a loss of power in the signal that the break in the transmission line shows. “Return loss” is expressed in decibels.
“Return loss” suggests that how much power was transferred to the load. If all power has been transferred. The return loss will be infinite. And if not all the mobility has been transferred, the return loss will be zero. To measure return loss, you need to use a SWR meter with feeders or transmission lines.
There are many standing wave ratio meters available and they come at different price points. Some meters measure several bands, including UHF and VHR frequencies.
Actually, the best SWR meter for ham and CB radios is a very relative thing. That is why before buying an SWR meter you need to know the exact characteristics of your antenna and radio.
