Antenna Cable - SMA Male To SMA Female:

  • One end has an SMA-male and the other end has an SMA-female connector.
  • See other length options of this SMA extension cable.
  • The length refers to the length of the cable between the connectors (not including the connectors).
  • Data Alliance's high-quality soldered terminations of SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

Cable is double-shielded, low-loss and very flexible/easily bendable coax with black jacket. The double-shielding is a major factor in the higher quality of this cable, which translates into lower loss/better performance. Rated for outdoor use and suitable for indoor use.

We offer two options of thickness of 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 higher quality of the cable translates into lower loss/better performance. Cable is equivalent to LMR-100 in thickness. Recommended tightest continuous bend radius is 1.1 inch (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.
  • Comparison of attenuation (signal loss) of LMR-100 and LMR-200.

SMA LMR100 and LMR200 characteristic comparison.

The temperature range for operational use of these cable assemblies are 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)

SMA female connector includes a bulkhead nut and washer for mounting and/or weatherproofing the connector / port:

  • 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 mount the connector on a case, panel or Printed Circuit Bard (PCB).
  • Weatherproofing: Seal the hole where the female connector is mounted, by placing an O-ring between the wall of the enclosure and the bulkhead nut & washer on the female connector.
  • All of our cables with SMA and RP-SMA female connectors have bulkhead mount hardware.
  • The length of our standard SMA-female connector (threaded part) is 3/8 inches. We have a longer option: 14.5mm, which is available as an option. The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.
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-male has a pin inside the connector body

SMA Gender Determination: Key Point

  • 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.

Compatibility with wireless applications: Our 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, suitable and compliant for all the following applications:

ROHS 3 & REACH: Compliant with the RoHS & REACH restrictions on content of lead, other heavy metals and toxins.

    Really great cable, well made, have now ordered several of these. Price is right, but what really blew me away was the lightning fast shipping, AZ to NY in 2 days!

    excellent quality and fast shipping

    Very happy. Top shelf, low loss, quality SMA extensions. Used for drone FPV diversity setup. Worked perfectly. Those clear coat laminate cables are garbage compared to these!

    High quality cable

    I got the 2 inch for an FPV upgrade. Very well made. The cable was thicker than I expected and actually a little too stiff. The fact that you can get this in the US at this price is much better than looking on Amazon.

    Our company has ordered a number of these cables and to my knowledge, have not had any issues. Ordering is quick and easy. Delivery is prompt.

    Good company.
