    Perfect cables for us

    Posted by Bryon on 21st Mar 2018

    We were putting our Symbol Wireless Access points inside a enclosure and wanted the antennas on the outside of the enclosure and these cables worked perfectly. we drilled 3 holes in the enclosure and then inserted the Male end through and used the bulkhead nut and washer to secure the cables. then we attached the cable to the AP and the Antennas to the male end outside the box. the cables are very high quality and we experienced no signal loss. i was also happy with how quickly they shipped. would definitely buy from this supplier again.

    Exactly what I needed

    Sparkfun discontinued their similar product - and this is a well built inexpensive replacement. Service from Data Alliance was extremely helpful, personal, and fast

RP-SMA Extension Cable

RP-SMA Female to Male Antenna Cable

  • One end has an RP-SMA male connector, and the other has an RP-SMA female connector with a bulkhead nut & washer for mounting and weatherproofing.
  • Other lengths of our RP-SMA extension cables from inches to meters.
  • The cable length stated in the length options is between the connectors.
  • The connectors are straight RP-SMA male and straight RP-SMA female connectors with bulkheads.
  • Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

The cable is double-shielded, low-loss, and very flexible/easily bendable. The cable type is equivalent to or better than LMR-100: Coax with black jacket has the same or better signal-loss-per-meter and flexibility as LMR-100 and less attenuation (signal loss) than RG174. The higher quality of this antenna cable coax translates into lower loss/better performance. The cable is equivalent to LMR-100 in thickness. This cable is rated for outdoor use and is also suitable for indoor use. Impedance is 50 Ohms.

We have the 18-inch version available in both LMR-100-equivalent and LMR-200-equivalent coax types.  If you wish to order the 18-inch version in LMR-200-equivalent coax (Part# is E0c200),  don't hesitate to contact Customer Service.  

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

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 mount the connector on a case, panel, or Printed Circuit Board (PCB).
  • The RP-SMA female connector is designed with weatherproofing in mind. You can seal the hole where the female connector is mounted by placing an O-ring between the enclosure wall and the bulkhead nut & washer on the female connector. This ensures your connection is protected from the elements, making it suitable for outdoor use.
  • Our standard RP-SMA female connector (threaded part) is 3/8 inches long. We also offer a more extended option: 14.5mm. The longer option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.
  • The 18-inch version has the option of the elongated RP-SMA female (14.5mm), and this option also has an embedded o-ring embedded in the flange: Part# RSm18iRSfLo
  • All our cables with SMA and RP-SMA female connectors have bulkhead mount hardware.


Compatibility: Our RP-SMA extension cables ' range of frequency band compatibility (from 0GHz to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm cables makes them compatible and compliant for all the following applications:


Regarding,"      quality and compliance, our antenna cables leave no room for doubt. They are meticulously crafted to comply with ROHS 3 and REACH restrictions, ensuring they are free from lead content, other heavy metals, and toxic materials. You can trust our cables to deliver high performance while meeting the highest safety standards.

The RP-SMA male-to-female extension cable is designed for easy and quick installation. The RP-SMA male connector is a perfect fit for the jack on most WiFi routers, while the RP-SMA female connector is designed to fit the male connector on antennas with an RP-SMA male connector. Most WiFi antennas with an RP-SMA connector have a male connector. This extension cable allows you to place the antenna further from the router, in the most suitable place for line of sight, without any hassle.
