What is SWR meter?
The ratio of the permanent wave (SWR) indicates the exact voltage or current produced by the radio and its accompanying antenna. Measured by the SWR meter defines the ratio between the output power generated by the radio transceiver and the lowest voltage or current level that reaches from the antenna to the electronics. No force that would bounce back into the radio transceiver electronics would be equal to one to one. Defects in any radio system component, including cables, connectors and handles, can increase the ratio of the measured SWR meter.
SWR meter is the most accurate when it is between the antenna and the radio. The coaxial cables are connected to the meter from the radio and the antenna. Switching to the device allows you to read either reflected power or forward performance, a combination of power that goes out and is diverted back to the radio. Digital or analog reading on the front side of the SWR meter will indicate whether a rat standing voltage wave is too high by showing the level entering the established red zone.
When the SWR meter registers too high, it can be due to a short connector. The operator could also check how the mounting pins were installed or that they work properly. Mounds antennas that are not grounded or cables could also cause SWR to be high. The problem can be measured on different channels to better understand it. Operating the radio before repair could damage the system outside the repair.
antennas and radio transmitters must be connected by some kind of connection. These wires and associated coaxial connectors often lose some energy, causing signals to be brought back to the transmitter. When the antenna and transmitter have the same power, they say they agree, and the level of this comparison is an impedance. They rarely have both components the same impedance, so the swrumrum usually registers the ratio of the imperfect ratio.
SWR does not cause any effect on the admission end of the radio system many times. If SWR does not register onTwo to one, the ratio will not result in a loss of energy that anyone can recognize at both ends. If enough energy is diverted back to the transceiver, the electronics can overload and abbreviation. Power protection circuits can scan excess current and voltage and automatically reduce the transmitter output to a safe range.
