  But beware doing it "cross species" - the male pin of an
  PL-259 connector can be forced into a female N connector by
  tightening the shell threads, thereby ruining the N-connector.

  One of our served agencies found that out the hard way when
  one of their set-up mechanics tried to hook up the wrong end of
  the antenna cable and they had to buy us a new Dual-Band antenna.
