    The problem is that most of the antennas are fake nagoya, and they are not tuned in

    You cannot measure these antennas in this way. They need some grounding to work properly. When you hold handy radio then you are ground. When you put it on antenna analyzer as you did, there is no good enough ground.

    Not everybody knows with those readings mean would it kill you to explain it which ones are good or bad

      SWR when is lower than is better, ideal is 1. That means 100% of power is emmited. When SWR is 1,5 then reflected power is 4% and emmited 96% so we loose some power. When SWR is 3 we loose 25% of power etc. More details www.arrl.org/files/file/Technology/tis/info/pdf/q1106037.pdf

    That was twenty-one seconds of usable information, eight minutes of watching you fiddle with an antenna analyzer, which, I suppose, wouldn't have been so bad if I could understand what you were saying.

    Turned off as soon as I seen baofeng, its not a proper radio, all the power goes out in spurious emissions.
