RP-SMA Male to Female Cables 12FT to 50FT

  • One end has an RP-SMA female connector, and the other has an RP-SMA male connector.
  • We understand that different setups require different cable lengths. That's why we offer a range of options, from a compact six meters (20 feet) to a generous 50 feet, allowing you to choose the perfect fit for your application.
  • See other lengths of this RP-SMA extension cable.
  • Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.
  • Former Part # E8 is now RSm25ftRSf200

We offer two options for the thickness of the cable (both are double-shielded, with a black jacket): LMR-400 and LMR-200:

  • Our 400-series coaxial cable type, equivalent to LMR-400, offers significantly lower attenuation (signal loss) than the 200-series. These cables, featuring nickel-plated brass connectors, are the most corrosion-resistant plating available for antenna cable connectors, making them ideal for outdoor and indoor use.
  • 200-series coaxial ca ble-type (equivalent to LMR-200) has much lower attenuation (signal loss) than LMR-100 and RG58. All the cables on this page that are 200-series coax have gold-plated brass connectors.
  • In both cases of coax types, the cables are rated for outdoor use and suitable for indoor use.
  • The double-shielding of both 200-series and 400-series cables enables low signal loss. Both are flexible and easily bendable (the 200-series is more flexible and bendable). Double-shielding is a significant factor in the higher quality of this cable, which translates into lower loss and better performance.

The temperature range for operational use of these 200-series and 400-series cable assemblies is as follows: -31 F ~ +203 F (-35 C ~ +95 C)

Special versions:

  • We have a 25-FT version with an elongated threaded section of the RP-SMA-female connector (14.5mm threaded section). The part number for this is RSm25ftRSfL200 (To order this, contact Customer Service). Our standard 25-ft version is part# RSm25ftRSf200 (which can be ordered on this web page).  
  • We can produce any length or version with the more extended threaded section of the RP-SMA-female connector (as a particular order):  Contact Customer Service.

Coaxial Cable Types for Long RP-SMA Extension Cables:  LMR-200 and LMR-400

LMR-200 and LMR-400 are low-loss coaxial cables manufactured simply for transmitting radio frequency signals in antenna cables. They are suited to many practical industrial uses, including Wi-Fi, Bluetooth, and broadband internet networks.  

Before we delve into the details of the product, let's define what a low-loss coaxial cable is. The composition of a typical coaxial cable is as such:

  1. Copper clad-steel conductor - low impedance and high tensile strength conducting wire
  2. Dielectric PE foam - relatively minimal absorption of electrical charge
  3. Double shielding - both aluminum foil and braided copper for the blocking out of any environmental signal disturbance
  4. Outer Jacket—UV stable and flame retardant protective casing that is ideal for indoor and outdoor environments from the day of installation for years to come.

The following is a simple head-to-head comparison between LMR-400 and LMR-200 low-loss RF coaxial cables:

Composition

1. Inner conductor

  • LMR-200 conductor: under 1.42 mm in diameter
  • LMR-400 conductor: above 2.74 mm in diameter

2. Dielectric foam diameter & material

  • LMR-200 foam diameter: 3.81 mm, Polyethylene foam
  • LMR-400 cable sheath: 7.24, Polyethylene foam

3. Inner shield

  • LMR-200 inner shield: tinned copper braiding
  • LMR-400 inner shield: (same as above)

4. Outer shield

  • LMR-200 outer shield: aluminum foil
  • LMR-400 outer shield: (same as above)

5. Outer cable sheath diameter, material & color

  • LMR-200 cable sheath: under 6.1 mm in diameter, Polyethylene, black
  • LMR-400 cable sheath: above 10.29 mm in diameter, Thermoplastic elastomer, black

Some other associated physical characteristics of LMR-200 vs LMR-400

Temperature stability = both max. Eighty-five degrees C / min. -40 degrees C, they are suitable for work in extremely hot or cold environments. Bending radius =  a single bend of LMR-200 and LMR-400 have radii of over 19 mm and under 25 mm, respectively. The double bend is over 63 mm for LMR-200 and below 102 mm. Weight = the LMR-200, at 0.06 kg/m, is just under half as heavy per m as LMR-400, at 0.102 kg/m. Neither cable needs a trailing cable nor contains halogen in its material makeup.

Attenuation

The following data quantifies the estimated loss of signal strength typically attributed to the LMR-200 and LMR-400:

At 900 MHz

  • LMR-200 = 0.09 dB/ft.
  • LMR-400 = 0.039 dB/ft.

At 2400 MHz

  • LMR-200 = 0.12 dB/ft.
  • LMR-400 = 0.066 dB/ft.

At 3500 MHz

  • LMR-200 = 0.21 dB/ft.
  • LMR-400 = 0.081 db/ft.

At 5800 MHz

  • LMR-200 = 0.264 dB/ft.
  • LMR-400 = 0.108 dB/ft.

Double shielding benefits

Both cables are double-shielded, with aluminum foil (100%) and copper braiding (70%+), for maximum signal protection from EMI/noise. This combination of shielding methods provides maximum noise attenuation and interference annulment.

RP-SMA Gender Determination: Key Points

  • RP-SMA gender is counter-intuitive.
  • The gender refers to the pins inside the threads. RP-SMA male has threads on the inside.
  • RP-SMA (reverse polarity) means that the pin and socket configuration is the opposite of what you would expect: RP-SMA female has a pin inside, and RP-SMA male has a socket inside.
  • More details regarding SMA & RP-SMA gender determination.

    Worked great to extend my wireless camera range by moving the antenna.

    Great solution to a problem

    Posted by Unknown on 8th Feb 2018

    I needed to extend the range of a wire-free security camera, and felt the best solution was this extension cable. Worked like a charm. The only negative I had was on the product name... sounded like 2 slightly different-length cables. I expected, and received, only one cable per order, so had no surprise. I was unfamiliar with this type of cable, so perhaps the nomenclature is standard.

    large

    The cable is very large . Outside is close to 3/8" .not easy to hide because of its size
