    Just what I was looking for and could not find..

    It was exactly what I needed it fits perfectly, works perfectly, mounts perfectly. I order another one actually already.

RP-SMA Female to RP-SMA Female Adapter

 RP SMA Female to RP SMA Female Connector Type

  • One side of the adapter features a large bulkhead nut, with an outer diameter of 12.70 mm. This nut is significantly larger than the standard bulkhead for RP-SMA, providing enhanced stability and durability in high-frequency applications.
  • Rest assured, our RP-SMA Female to RP-SMA Female Adapter comes with a reliable red O-ring that forms a robust waterproof seal in the port of an enclosure or panel. The adapter is available in two options: gold-plated and nickel-plated. The nickel-plated brass option is the most corrosion-resistant of all plated brass alloys, surpassing the corrosion resistance of gold-plated options. This makes it ideal for applications in corrosive environments or those requiring long-term durability. A second nickel-plated version has a Delrin (white plastic) cap for the flange so it will not contact a metal surface: Part# RSfRSfOP.
  • The thicker middle section (where the bulkhead nut resides) has a flat element to prevent turning while inserted in the panel (known as a "dhole")
  • Enables connection/coupling of two RP-SMA male connectors: Bulkhead Feedthrough Adapter.
  •  Impedance: 50 Ohms
  • IP68 waterproof rating.
  • ORING is UL-listed.

Compatibility with wireless standards & applications :

The RP-SMA Female to RP-SMA Female Adapter is compatible with a wide range of wireless standards and devices. It is suitable for all Helium miners in North America, including Bobcat miners, Sensecap miners, and all other Helium LongFi miners. Additionally, our antenna cables and adapters with RP-SMA-male connectors are compatible with this adapter, making it a versatile solution for your wireless communication needs. Our RP-SMA Female to RP-SMA Female Adapters' range of frequency band compatibility (from 0GHz to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm cables make them compatible, suitable, and compliant for all the above applications.

RP-SMA Connector Characteristics and Details: 

RP-SMA female connector includes a bulkhead nut and washer for mounting & waterproofing:

  • You can use this hardware to mount the connector (and thus the cable) on the wall of a network enclosure (to weatherproof the cable connection) or on a case, panel, or Printed Circuit Board (PCB).
  •  Weatherproofing: Seal the hole where the female connector is mounted by placing an O-ring between the enclosure's wall and the bulkhead nut and washer on the female connector.
  • Our standard RP-SMA-female connector (threaded part) length is 3/8 inches. We have a more extended option: 14.5mm, which is available. The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.
  • Our cables with SMA and RP-SMA female connectors have bulkhead mount hardware.

RP - SMA  Female torque rating

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 Connector Materials Composition :

  • Connector Body: Gold Plated Brass
  • Center Contact: Beryllium Copper, Gold Plated
  • Crimp Ferrule: Copper, Nickel Plated
  • Insulators: PTFE
  • Precision machined for low loss in ISO 9001 facilities.

Insertion loss: 0.26 dB maximum

Our antenna cables and adapters pass QC tests before we ship them.
