Standing wave ratio can be very important when using a transmitter. If the level of standing waves is too high then it can either damage the transmitter or transceiver output, or cause it to reduce its power. So measuring the SWR is important. Knowing how to use an SWR meter and connect it up can be vital and it is described in this video along with some key hints and tips on how to use the SWR meter and gat the best from it.

SWR bridges or SWR meters come in many forms. They don’t have to cost too much, although higher price ones do give better performance and they can measure more parameters like power levels.

The video describes how to connect the SWR meter into the feeder and then how to use it making sure that no undue interference is caused.

The video also describes the various points where SWR meters can be sued and their advantages and disadvantages. It also describes how to use the SWR meter when an ATU is present.

Another interesting points is the feeder loss and know how this affects the SWR readings. High feeder loss can make an antenna with a high SWR look much better, so it gives guidance on this. The video also gives a few useful bonus tips on how to use the SWR meter as well.
