    Quality at a fair price

    Posted by Scott Swenson on 3rd Apr 2025

    This cable is astonishingly well-made. Don't even bother with those ones off Amazon for the same cost. This is cable has great strain reliefs, is easily twice the thickness yet is still flexible. I have no worries this will long outlast the one it is replacing from the country that gave us Baofeng.

    Exactly the part I needed

    Posted by MK on 20th Jul 2016

    I needed to extend several antennas from their mounting on a base unit to the outside of a case the base unit was mounted within. These cables matched perfectly and made the job an ease. And, for less money that it would have cost me to make them up myself. I was impressed with the selection offered, and the speedy delivery.

SMA Male to Female Cable:  18 inches to 30 inches.

Antenna Cable: SMA Female to SMA male Extender: One end has an SMA male, and the other has an SMA-female connector.

The length refers to the cable size between the connectors (not including the connectors).

The cable, designed for outdoor and indoor use, is double-shielded, low-loss, and remarkably flexible. Its black jacket adds to its durability, ensuring it can withstand various environmental conditions. Double-shielding is a key feature contributing to the cable's superior quality, resulting in lower loss and better performance.

Data Alliance's high-quality soldered terminations of SMA connectors are meticulously crafted, providing a low-loss connection. This precision ensures that discontinuities are kept to an absolute minimum, guaranteeing a reliable and consistent performance.

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

  • The LMR-100-equivalent cable type is not just equivalent but often surpasses LMR100. It boasts the same or better signal loss per meter and flexibility as LMR100 and even less attenuation (signal loss) than RG174 and RG178. This superior performance directly results from the cable's high quality, which translates into lower loss and better performance.
  • The LMR-200-equivalent cable type is equivalent to or better than LMR200: It 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.

Attributes comparison of LMR100 and LMR200

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 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 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's wall and the bulkhead nut and washer on the female connector.
  • Rest assured, all our cables with SMA and RP-SMA female connectors come with the necessary bulkhead mount hardware, ensuring a complete and hassle-free setup.
  • Our standard SMA-female connector (threaded part) is 3/8 inches long. We also offer a longer option: 14.5mm.
  • The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.
  • For the 20-inch version and 24-inch versions:  We have two different female connectors options in stock:   O-ring embedded in the flange/bulkhead (11mm diameter flange), or the smaller 8mm diameter flange with no embedded o-ring.  If you have a preference for the version with the o-ring (part# Sm20iSf7), please contact customer service.
