If the return loss is 10 dB, 10% of the power is returned. While different systems have different acceptable return loss limits, 15 dB or better is a common system limit for a cable and antenna system.
2020年10月30日 — For instance, if the return loss is 10 dB, then the return is 10% of the power. Different systems utilize different acceptable return loss ...
2023年6月19日 — When the return loss is <10dB, the antenna will be at VSWR >2, indicating the system will reflect >30% power and the performance of the antenna will be <70%.
2019年9月15日 — If you have return loss < 10 dB it means that your antenna VSWR will be > 2, which means that about 30% of your signal will be reflected ...
2021年8月20日 — 10 dB return loss does not mean 90% of the power is transferred to the load, it means 10% of the power came back. Less than 90% may have reached ...
