A few questions about Metal 2SHPn

Hi everyone, I have a few questions about my Metal 2SHPn.

  1. Are there any low gain antenna for it? I want one made by Mikrotik but I cannot find any.
  2. I have powered it on a few minutes without an antenna, but it works OK now, I’ve heard this will damage the RF chip, what’s the truth?
  3. I want to remove the buzzer, but when I took it apart I can’t find any, it’s soooo strange!
    Any ideas? Thanks!
