    Impressed with quality of food his wire. Ends are good quality and cable seems sturdy while being flexible

RP-SMA Extension Cable

RP-SMA female to male Antenna Cable Extender:

  • Our RP-SMA Extension Cable is unique. It has an RP-SMA female right-angle connector on one end and an RP-SMA male right-angle connector with a bulkhead nut and washer for mounting and weatherproofing on the other. This design ensures easy installation and protection against weather conditions.
  • 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.

Our RP-SMA Extension Cable is flexible and easily bendable, and it's also double-shielded with a black jacket. This high-quality construction, including the double-shielding, ensures its durability and superior performance.

We offer two options for the thickness of the cable (both are double-shielded):

  • The LMR-100 equivalent cable-type is equivalent or better than LMR100: Has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG174 and RG178. The LMR-100 equivalent cable type is equivalent or better than LMR100: It has the same or better signal loss per meter and flexibility as LMR100 and less attenuation (signal loss) than RG174 and RG178. This antenna's higher quality cable translates into lower loss/better performance. The cable is equivalent to LMR-100 in thickness. The recommended maximum bend radius is 1.1 inches (28mm).
  • The LMR-200-equivalent cable-type is equivalent or better than LMR200: Has the same or better signal-loss-per-meter and flexibility as LMR200, and less attenuation (signal loss) than RG58.
  • See comparison of LMR-100 and LMR-200 attenuation (signal loss).

The temperature range for the operational use of these cable assemblies is as follows:

  • Cables with 100-series coax: -22 F ~ +185 F (-30 C ~ +85 C)
  • Cables with 200-series coax: -31 F ~ +203 F (-35 C ~ +95 C)




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

  • This can be used 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 wall and the bulkhead nut & washer on the female connector.
  • The length of our standard RP-SMA-female connector (threaded part) is 3/8 inches. We have a longer 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.

Compatibility with wireless standards & applications:

Our RP-SMA extension cables' range of frequency band compatibility (from 0 to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm antennas and cables make them suitable and compliant for all the above applications.

ROHS 3 and REACH: Our antenna cables comply with ROHS 3 and REACH restrictions on lead content, other heavy metals, and toxic materials.

RP-SMA male-to-female extension cable is easy and quick to install: The RP-SMA male connector fits the jack on most WiFi routers, and the RP-SMA female connector fits the male connector on antennas with an RP-SMA male connector: Most WiFi antennas with an RP-SMA connector have a male connector. The extension cable enables the antenna to be placed further from the router in the most suitable place for line of sight.
