SWR - What does SWR stand for? The Free Dictionary

WebThe term “SWR” means standing wave ratio. An “SWR” meter is used to measure how well the transmit power signal emitted from a transceiver (radio) is traveling through the … WebReturn Loss. This bounce back reflection is called “return”. Return loss is the measure of how small the “return” or reflection/echo is. We want a small return, so a large loss on the return “echo” is good. Smaller return loss is bad, and means less energy is going into our antenna. RF engineers often measure return loss on a “dB ...
