What SWR means?
Standing-wave ratio (SWR) is a mathematical expression of the non-uniformity of an electromagnetic field (EM field) on a transmission line such as coaxial cable. Usually, SWR is defined as the ratio of the maximum radio-frequency (RF) voltage to the minimum RF voltage along the line. The ideal VSWR is therefore 1:1.Click to see full answer….

Likewise, people ask, what does SWR mean slang?Meaning. SWR. She Wants Revenge (band)Likewise, is 1.5 SWR good? SWR 1.0-1.5: The ideal range! If your SWR is under 1.5, you’re in great shape. SWR 1.5 – 1.9: There’s room for improvement, but SWR in this range should still provide adequate performance. Occasionally, due to installations or vehicle variables, it’s impossible to get SWR lower than than this. Then, what is a good SWR? The best reading possible is 1.01:1 (46dB return loss), but usually a reading below 1.5:1 is acceptable. Outside the perfect world a 1.2:1 (20.8dB return loss) is spot on in most cases. To ensure an accurate reading, it is best to connect the meter at the base of the antenna.What should my SWR reading be?The SWR reading indicates how much of the radio’s power is being turned into radio signals by the antenna. If you have an SWR ratio reading of 1.0, that indicates that 100% of the radio’s power is being transmitted. A ratio of 3.0 is registered when the antenna is only transmitting a third of the radio’s power.
