Antenna CableSMA Male To SMA Female:  

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 female connector includes a bulkhead nut and washer for mounting and/or weatherproofing the connector / port: 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 Gender Determination:  Key Point 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
Other SMA Characteristics and Key Points
  • SMA female connector is also called "jack" and SMA-male is also called "plug."
  • 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 is a round screw-type connector, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.

Compatibility with wireless applicationsOur 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 compatiblesuitable 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!

    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.
