What is SWR bandwidth?
In radio engineering and telecommunications, standing wave ratio (SWR) is a measure of impedance matching of loads to the characteristic impedance of a transmission line or waveguide.
How can I boost my SWR 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 should I do if my SWR reading is higher than channel 40?
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. 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.
What should the SWR be on a CB antenna?
Checking and setting the “SWR” on all radio applications is the most important step in obtaining the best performance possible. When testing and adjusting the antenna, make sure to check “SWR” on the lowest channel and the highest channel.
What does a poor SWR reading mean on a radio?
A poor reading on the “SWR” meter will provide you with your SWR readings which can indicate that there is a problem with installation of your radio or antenna system. When the “SWR” test is performed, the meter will indicate if your antenna is working properly and provide a reading so the antenna can be adjusted for optimum performance.
Do you have to have a SWR meter on Your Radio?
DO NOT OPERATE THE RADIO UNTIL A GOOD “SWR” READING CAN BE ACHIEVED. Some radios include a built-in meter while other compact radios do not. If you do not have one built-in to your radio, you will need to get one so that you can tune your antenna for your application.
