SMA Extension Cable

Antenna Cable: SMA Male To SMA Female low-loss cable: LMR200 equivalent with regard to signal retention.

  • Other lengths of our SMA Extension Cables
  • One end has an SMA-male and the other end has an SMA-female connector.
  • 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 for low-loss but is very flexible/easily bendable. The cable-type is equivalent or better than LMR200: Coax with black jacket has the same or better signal-loss-per-meter and flexibility as LMR200, and less attenuation (signal loss) than RG58. The higher quality of the cable of this antenna translates into lower loss/better performance. Cable is equivalent to LMR-200 in thickness.

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)

Compatibility: 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 and compliant for all the following applications:

ROHS & REACH compliant: The entire product (connectors and cable) is free of heavy metals and compliant with ROHS and REACH.

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 cable versions on this page, and others by special order. The longer SMA-female version (top in photo) has a 14.5mm threaded section. It is available for some cable versions on this page, and others by special order.


SMA Connector Characteristics and Details

  • 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-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
  • SMA-female connector fits items that have an SMA (female) jack/connector.
  • 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. More details regarding SMA gender determination.
  • SMA female connector is also called "jack" and SMA-male is also called "plug."
  • 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.
  • We offer an SMA wrench to assist in installing antennas, cables and adapters with SMA or RP-SMA connector(s).
