SMA female To RP-SMA male Cable

Antenna Cable / Adapter Cable: SMA female To RP-SMA male (for antenna): One end has an SMA female connector and the other end has an RP-SMA male connector. Double-shielded cable.

  • The length refers to the length of the cable between the connectors (not including the connectors).
  • One end has an RP-SMA-male connector, and the other end has an SMA-female connector with bulkhead mount (nut and washer).
  • If the part number ends with 5, the flange (on the female end) is 5/16" in diameter (and has no embedded o-ring). If the part number ends with 7, the flange is 7/16" in diameter and comes with an embedded black o-ring: See photo of the flange options.
  • See details regarding the SMA female connector below on this page: Weatherproofing, mounting, and length options.
  • Data Alliance's high-quality soldered terminations of SMA and RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

Antenna Cable Coax is double-shielded, low-loss and very flexible.

  • The cable-type is equivalent or better than LMR-100: Coax with black jacket has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG174.
  • This cable is rated for outdoor use and is also suitable for indoor use .
  • The higher quality of the cable of this antenna translates into lower loss/better performance.
  • Cable is equivalent to LMR-100 in thickness.
  • Recommended tightest bend radius is 1 inch (28mm).

The temperature range for operational use of this 100-series coax and the cable assembly, is: -22 F ~ +185 F (-30 C ~ +85 C)

SMA & RP-SMA Connector Characteristics and Details

SMA Female Version Options SMA Elongated
The version of the SMA female connector on the left has an embedded o-ring, together with a wider flange, for more secure protection against intrusion of water and/or dust and dirt. It is available for some of our "stocked" SMA cable versions, and others by special order. The longer SMA-female version (top in photo) has a 14.5mm threaded section. It is available for some of our "stocked" SMA cable versions, and others by special order.


  • SMA female connector includes a bulkhead nut and washer:
    • SMA & RP-SMA male and female diameter:
      • SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
      • SMA male inside diameter is 5/16" (7.9375mm) (the inside diameter where the threads are).
    • SMA & RP-SMA Gender Determination: Key Points
      • SMA gender is counter-intuitive: Please observe picture & note it is correct.
      • The gender is referring to the pins inside--not the threads. SMA male has threads on inside.
      • RP-SMA (reverse polarity) means that the pin and socket configuration is the opposite of what you would expect: RP-SMA female has a pin inside, and RP-SMA male has a socket inside.
      • More details regarding SMA & RP-SMA gender determination.
    • Other SMA & RP-SMA Characteristics and Key Points
      • SMA female connector is also called "jack" and SMA-male is also called "plug." The same holds for RP-SMA female and male.
      • We offer an SMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
      • SMA-female connector fits items that have an SMA-male connector.
      • SMA and RP-SMA are round screw-type connectors, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.
