RP-SMA Connector Characteristics and Details

• RP-SMA female and male diameter:
• RP-SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
• RP-SMA male inside diameter is 5/16" (7.9375mm) (the inside diameter where the threads are).

• RP-SMA Gender Determination:  Key Points
  • RP-SMA gender is counter-intuitive: Please observe picture & note it is correct.
  • The gender is referring to the pins inside--not the threads. RP-SMA male has threads on inside.
  • RP-SMA male has a socket inside rather than a pin, as you might expect, because the RP stands for "Reverse Polarity."  The socket/pin configuration is female when it appears to be male, and vice versa.

• Other RP-SMA Characteristics and Key Points
• RP-SMA-male is also called "plug" and SMA female connector is also called "jack"
• We offer an RP-SMA wrench to assist in installing antennas, cables and adapters with RP-SMA or SMA connector(s).
• RP-SMA-male connector fits items that have an RP-SMA-female connector.
• RP-SMA is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.
• RP-SMA connectors are not compatible with the common, commercially available Type F coaxial connector. Type F connectors look similar but are of slightly different size and will not pair with RP-SMA or SMA connectors without an adapter.
• We offer an RPSMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
• RP SMA is also known as SMA RP, SMA-R, SMA-RP, SMA R
