RP-SMA Extension Cable: 20FT, 22FT, 25FT, 30FT, 35FT, 40FT, 50FT Low Loss

Antenna Cable: RP-SMA Male to RP-SMA female

• One end has a RP-SMA female connector, and the other end has a RP-SMA male connector.
  
• Choose between length options, above: Six meters (20 feet) up to 50FT.
• 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

The version of the RP-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 RP-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.

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

• 400-series coaxial cable-type (equivalent to LMR-400) has much lower attenuation (signal loss) than 200-series. All the cables on this page that are 400-series coax have connectors that are nickel-plated brass (on the connector body) . Nickel-plated brass is the most corrosion-resistent plating available for antenna cable connectors.
• 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 connectors that aregold-plated brass.
• In both cases of coax types, the cables are rated for outdoor use and are also suitable for indoor use.
• Double-shielding of both 200-series and 400-series enables low signal loss. Both are flexible/easily bendable (200-series is more flexible/bendable). The double-shielding is a major factor in the higher quality of this cable, which translates into lower loss/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# for this is RSm25ftRSfL200 (To order this, contact Customer Service).  Our standard 25ft version is part# RSm25ftRSf200 (which can be ordered on this web page).  
• We can produce any length or version with the longer threaded section of the RP-SMA-female connector (as a special order):  Contact Customer Service.

Compatibility with wireless standards & applications:

• All WiFi standards: 2.4GHz and 5GHz applications: 802.11AC, 802.11N, 802.11G, 802.11B, 802.11A
• Cellular Wireless LTE / 4G, GSM / 3G WiMax: Data and voice applications
• IoT wireless, automation & M2M: Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT.
• Compatible with all Helium miners used in North America, including Bobcat miners, Sensecap miners and all other Helium LongFi miners, as are all of our antenna cables and adapters with RP-SMA-male connectors

Our RP-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 above applications.

RoHS 3 and REACH compliant: All of our antenna cables and RF adapters are compliant with RoHS 3 and REACH restrictions on content of lead and other heavy metals and toxins.

RP-SMA female and male diameter:

• RP-SMA female outside diameter is 5/16" (7.9375mm): Accommodates a hex nut (bulkhead nut) with 5/16" nominal outer diameter
• RP- SMA male inside diameter is 5/16" (7.9375mm) (the inside diameter where the threads are).

RP-SMA Gender Determination: Key Points

• RP-SMA gender is counter-intuitive.
• The gender is referring to the pins inside-not the threads. RP-SMA male has threads on 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.

Other RP-SMA Characteristics and Key Points

• SMA female connector is also called "jack" and SMA-male is also called "plug". The same holds for RP-SMA female and male.
• 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 and RP-SMA are round screw-type connectors, with medium-sized, threaded coupling connectors that are rated for frequencies from the lowest (DC) up to 18GHz.

RP-SMA and SMA Connector Composition: Our SMA and RP-SMA connectors are precision machined and gold-plated for low loss.

• Connector Body:
  • All the cables on this page that are made with 400-series coax have connectors that are nickel-plated brass (on the connector body) .
  • All the cables on this page that are made with 200-series coax have connectors that are gold plated brass (on the connector body).
• Center Contact: Beryllium Copper, Gold Plated
• Crimp Ferrule: Copper, Nickel Plated
• Insulators: PTFE
• Precision machined for low loss in ISO 9001 facilities

RP-SMA male to female extension cable is easy and quick to install: The RP-SMA male connector fits the jack on WiFi routers, and the RP-SMA female connector fits the male connector on antennas with an RP-SMA male connector: Most WiFi antennas with an RP-SMA connector have a male connector. The extension cable enables placing the antenna further from the router, in the most suitable place for line of sight.
