ItвЂ™ll allow you to tune your radioвЂ™s antenna even in the dark. We highly recommend getting an SWR meter with a backlit display. Analogue meters are just as accurate as digital ones, though it can be a bit difficult to tell the exact number where the needle is resting. AnalogueДЄ surprising number of SWR meters are analogue, at a time when most devices are digital. Most SWR meters will also measure the output power and some display the frequency as well. In addition to SWR, check if the meter offers any additional measurements. Make sure you select a power level thatвЂ™s as close as possible but higher than your transmitterвЂ™s output. Some SWR meters come with a knob that allows you to adjust the power range depending on the output of your radio. Most SWR meters can handle at least 100W of power with pricier models having a range of up to 500W. If you have a CB radio, you donвЂ™t need to worry since the max output is only 4 watts (that is if the radio has not been modified to, illegally, increase power output). Different SWR meters are rated to handle varying power outputs. PowerДЄnother aspect that you need to match between your system and the SWR meter is power. If you are tuning a higher-frequency system such as a UHF or VHF radio, look for an SWR meter that accommodates the high frequency. If, like most people, you are buying an SWR meter to tune your CB radio, youвЂ™ll need a meter that covers the 26-27 MHz band (the legal frequency band for CB radios in both the UK and US). It is essential that you get an SWR meter that is compatible with the frequency range of your radio system.ДЄ mismatch between the frequency range of your radio and that of the meter will reduce sensitivity and lead to inaccurate measurement.

You can then measure the SWR for different frequencies. Use an SWR meter to get your systemвЂ™s SWR to this range.ДЄn SWR meter has two connections, one for the transmitter and the other for the feedline going to the antenna. A ratio lower than 1.5:1 across all channels is great. It means all the radioвЂ™s power is being transmitted as radio signals. When you are setting up an antenna, it is important to get the SWR as close as possible to 1:1. High SWR also reduces power output from the transmitter, which will lower transmission performance. A high SWR indicate high voltage, which can damage the feed line, transmitter and other components. SWR or standing wave ratio is the ratio of the highest voltage to the lowest voltage on the feed line, which is why an SWR meter is sometimes called a VSWR meter, with the V standing for voltage. This energy coincides with output from the transmitter going the opposite way, resulting in standing waves. They happen when the impedance of the feed line and the antenna do not match, causing some of the electrical energy sent to the antenna to be reflected back. Standing waves can also occur in RF transmission between the transmitter and the antenna. There are standing waves of water, standing waves in air and you can even make standing waves using a slinky. Standing waves are present in many kinds of situations. An SWR meter measures the standing wave ratio between an antenna and feed line, allowing you to adjust the antenna to the best length for signal performance and to prevent damage to your radio.
