TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
What is the difference between RPSMA and SMA contacts on antennas and pigtails?
SMA have two interfaces, male and female. A male interface have a pin sticking out in the middle and will be on the outside when screwed together with a female SMA. When a contact have RPSMA, or Reverse Polarity SMA, the pin in the middle will be flipped. So a RPSMA female have a pin in the middle, and a RPSMA male have a hole in the middle.
