RP-SMA Extension Cable: 21-inches Male to Female

RP-SMA female to male Antenna Cable

• One end has a RP SMA male connector, and the other end has a RP SMA female connector with bulkhead nut & washer for mounting and weatherproofing.
• Other lengths of our RP-SMA extension cables from inches to meters.
• The cable length stated in the length options is the length between the connectors.
• The connectors are straight RP-SMA-male and straight RP-SMA female connector with bulkhead.
• Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.

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.

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

• The LMR-100-equivalent cable-type is equivalent or better than LMR-100: Has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG-174 and RG-178. The higher quality of the cable of this antenna translates into lower loss/better performance. Cable is equivalent to LMR-100 in thickness.
• The LMR-200-equivalent cable-type is equivalent or better than LMR-200: Has the same or better signal-loss-per-meter and flexibility as LMR200, and less attenuation (signal loss) than RG58.
• See comparison of LMR-100 and LMR-200 attenuation (signal loss).

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)

RP-SMA female connector includes a bulkhead nut and washer for mounting & waterproofing:

• 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 mount the connector on a case, panel or Printed Circuit Bard (PCB).
• Weatherproofing: Seal the hole where the female connector is mounted, by placing an O-ring between the wall of the enclosure and the bulkhead nut & washer on the female connector.
• The length of our standard RP-SMA-female connector (threaded part) is 3/8 inches. We have a longer option: 14.5mm, which is available as an option. The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure

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.

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 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

RP-SMA Connector: Other Characteristics& Details:

• RP-SMA = Reverse Polarity SMA. Also known as SMA-RP, SMA-R, SMA RP, SMA R.
• The gender is referring to the pins inside-not the threads. RP-SMA male has threads on inside.
  
• RP-SMA female connector is also called "jack" and RP-SMA-male is also called "plug."
• RP-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 RP-SMA wrench to assist in installing antennas, cables and adapters with RP-SMA or SMA connector(s).
• RP-SMA connectors are not compatible with the common, commercially available Type F coaxial connector. Type F connectors look similar but are of slightly different size and will not pair with RP-SMA or SMA connectors without an adapter.

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, 5G: Data and voice applications
• IoT wireless, automation & Machine to Machine (M2M): Bluetooth, ZigBee, RFID, LoRa, LTE-m, NB-IoT.
• Compatible with allHeliumminers used in North America, including Bobcat miners, Sensecap miners and all other Helium LongFi miners, as are all of ourantenna cables and adapters with RP-SMA-male connectors .

Our RP-SMA extension cables' range of frequency band compatibility (from 0 to 18GHz), consistently low broadband VSWR, and impedance matching to 50 Ohm antennas and cables, makes them suitable and compliant for all the above applications.

ROHS 3 and REACH: All of our antenna cables are compliant with ROHS 3 and REACH restrictions on content of lead, other heavy metals and toxic materials.

RP-SMA male to female extension cable is easy and quick to install: The RP-SMA male connector fits the jack on most 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.
