Is SWR a good brand to buy?
The SWR pro series is reliable and great sounding. The famous mid scoop can be gotten around. Though they had a sound that went with an era their flexible tone shaping makes them timeless. My favorite sounds the least like the brand. The BBII. Whether they float your boat for your needs is for you to determine.
What is SWR and how does SWR work?
SWR results when the reflected power interacts with the forward power to create standing waves in the transmission line. These standing waves have a voltage maximum and a voltage minimum, as well as a current maximum and a current minimum.
Is it safe to operate my Radio in SWR range?
We advise you not to operate your radio in this range. SWR in this range is usually caused by a poor mounting location and/or a poor choice of equipment for your specific vehicle. To troubleshoot, you'll likely need to move the mounting location and/or use a more suitable antenna.
Are SWR meters easy to operate?
This model of SWR meter comes in a relatively common design, which makes it extremely easy to operate and function. There are just a few knobs and switches and you will soon figure them all out even without the manual. Moreover, the meter is small in size and light in weight, so it won’t take up too much space.
What is considered good SWR?
SWR Range Explanations. SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you're in great shape. If you're at 1.5 and really, really want to drop down to closer to 1 it's likely possible to do with addition tuning, different equipment or a different mounting location.
What SWR is too high?
For instance a SWR too high (over 3:1) all over the band can be an indication of a bad part or junction, poor ground or poor location. An SWR too low over the whole band (1:1 for all 40 channels) can indicate a low efficiency antenna or lossy component. Safe operation of your CB should be with an SWR of 2:1 or less.
What is a good SWR for ham radio?
The radio will receive and transmit well with a good “SWR” reading of 2.5 or less across all channels. The lower the “SWR” reading the better your radio will perform.
How do I get my SWR down from?
If your antenna is mounted down low on the vehicle, like on the bumper or behind a pickup truck's cab, the signal can bounce back to the antenna, causing a high SWR. To alleviate this, keep at least the top 12 inches of the antenna above the roof line, and position the antenna as high as possible on the vehicle.
Does coax length affect SWR?
Coaxial Cable Length Does Not Change Antenna SWR.
What does an SWR reading of 4 1 indicate?
What does an SWR reading of 4:1 indicate? Loss of -4 dB.
Does high SWR affect receive?
Simplified answer: There is no relationship between SWR and receive performance. There is one condition for this simplification to be true: the received RF noise floor must be above your receiver's noise floor.
What does an SWR reading of 1 1 mean?
What does an SWR reading of 1:1 mean? The best impedance match has been attained. An antenna for another frequency band is probably connected. No power is going to the antenna. The SWR meter is broken.
What is the difference between SWR and VSWR?
SWR is, thus, the ratio between transmitted and reflected waves. A high SWR indicates poor transmission-line efficiency and reflected energy, which can damage the transmitter and decrease transmitter efficiency. Since SWR commonly refers to the voltage ratio, it is usually known as voltage standing wave ratio (VSWR).
What causes high SWR?
One of the most common causes of high SWR readings is incorrectly connecting your SWR meter to your radio and antenna. When attached incorrectly, readings will be reported as being extremely high even if everything is installed perfectly. Please see this article on ensuring your SWR meter is properly installed.
How do you peak a CB radio?

And a couple of plastic alignment.
How do I adjust the SWR on my CB antenna?
Turn the radio to channel 1. Key the microphone (depress the button and hold it). Turn the knob on the SWR meter labeled “SET” or “ADJUST” until the needle reaches the setting position at the end of its range. While still keying the microphone, flip the switch on the SWR meter to the “REF” or “SWR” position.
What does it mean if your SWR is below 1?
NOTE: If your SWR reading is below 1, you have a problem. You might have a bad SWR meter, something wrong with your ante nna or antenna connection, or possible have a damaged or defective radio. If the SWR reading on channel 1 is higher than the reading on channel 40, your antenna system is too short and you need to lengthen your antenna.
What happens if SWR is higher than channel 40?
Alternatively, if the SWR reading on channel 40 is higher than channel 1, your antenna system is too long and you need to shorten your antenna system. IMPORTANT NOTE: Radio damage will only occur when you're TRANSMITTING from an antenna with high SWR readings.
What is SWR meter?
A “SWR” meter is used to measure how well the transmit power signal emitted from a transceiver (radio) is traveling through the antenna system into the atmosphere . Checking and setting the antenna is critical to overall performance of transceiver (radio). During installation of a Business Band, CB, Ham ...

What is a 1.1:1 VSWR?
A 1.1:1 VSWR means that if there were 10,000 watts transmitted, the reflected power would be about 23 watts. A VSWR of 2:1 means that with 10,000 watts transmitted, about 1,111 watts is reflected back towards the transmitter. If 100 percent of the transmitted power is reflected, the VSWR is infinity.
How does VSWR affect audio?
VSWR not only affects the efficient transmission of power but can have a severe effect on the transmitted audio. As a result of a mismatch, there is a portion of the RF signal that is reflected back towards the transmitter. When this reflected signal reaches the transmitter, it is reflected back towards the load.
Is VSWR equal to ISWR?
For most practical purposes, VSWR and ISWR are identical in value. SWR can be calculated from the formula: As you can see by the final expression, SWR and VSWR and ISWR are equal. The smaller the ratio, the better the match between the load and the transmission line.
What does VSWR stand for?
It officially stands for Voltage Standing Wave Ratio. This dimensionless ratio (no measurement units) is the same parameter as return loss, just expressed in a different scale. VSWR is somewhat old fashioned, and was often measured by the transmitter itself while transmitting into an antenna.
What scale do you measure return loss on?
RF engineers often measure return loss on a “dB” logarithmic scale, which can make it seem more complicated than it really is. However, just remember better return loss is indicated by bigger return loss numbers, and that is better for your antenna. Here are some examples of the logarithmic scale, or loss in decibels:
How to tell if antenna is poor radiation efficiency?
If you see changes in return loss, that means the antenna is “interacting” with it’s surroundings.
Can an antenna accept RF energy?
Measuring return loss during antenna design or verification is a powerful performance tool. Without good return loss, an antenna CANNOT accept your RF energy, and therefore cannot have it available to radiate. It is imperative that return loss goals and specifications be met. However, return loss does not tell the whole story.
Does poor return loss mean an antenna cannot radiate?
However, return loss does not tell the whole story. While it is true that poor return loss means that an antenna cannot radiate: It is NOT true that good return loss guarantees effective antenna radiation. Unfortunately, every week, we see antennas in our lab that radiate poorly, yet have a good return loss.
