RP-SMA Male to Female Cable
RPSMA male-to-female Antenna Cable
- One end has an RP SMA male connector, and the other has an RP SMA female connector with a bulkhead nut and washer for mounting and weatherproofing.
- The RP-SMA male-to-female cable is 1 meter long (3 feet 4 inches), providing ample length for various applications. Other lengths of our RP-SMA extension cables are from inches to meters.
- Directory of other RP-SMA cable types
- The cable length stated in the length options is between the connectors.
- The connectors are straight RP-SMA-male and straight RP-SMA female connectors with bulkheads.
- Data Alliance's high-quality soldered terminations of RP-SMA connectors with soldering provide a low-loss connection with discontinuities kept to a minimum.
The cable is double-shielded, low-loss, and very flexible/easily bendable. It is made of [specific material], which ensures its durability and weather resistance. The cable comes with a black jacket for added protection.
We offer two thickness options for this cable: Both are rated for outdoor use and suitable for indoor use.
- The 100-series coaxial cable type, equivalent or better than LMR100, has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG174 and RG178. The 100-series refers to [specific characteristic of the cable]100-series coaxial cable type is equivalent or better than LMR100: Has the same or better signal-loss-per-meter and flexibility as LMR100, and less attenuation (signal loss) than RG174 and RG178. The 100-series coaxial cable type is equivalent to or better than LMR100: It has the same or better signal loss per meter and flexibility as LMR100 and less attenuation (signal loss) than RG174 and RG178. This antenna's higher quality cable translates into lower loss/better performance. The cable is equivalent to LMR-100 in thickness. The recommended tightest continuous bend radius is 1.1 inches (28mm).
- The 200-series coaxial cable type is equivalent to LMR200: It has much lower attenuation (signal loss) than LMR-100 and RG58. It also has the same or better signal loss per meter and flexibility as the LMR-200.
- See a comparison of attenuation of 100-series and 200-series coax types (signal loss).
- Double-shielding is a significant factor in the higher quality of our cables: It translates into lower loss and better performance.
The temperature range for the operational use of these cable assemblies is 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)

- The RP-SMA female connector includes a bulkhead nut and washer for mounting and waterproofing. This feature allows you to mount the connector (and thus the cable) on the wall of a network enclosure, case, panel, or Printed Circuit Board (PCB). The bulkhead nut and washer provide a secure and weatherproof connection, ensuring the cable's longevity and performance.
- Weatherproofing: Seal the hole where the female connector is mounted by placing an O-ring between the enclosure's wall and the bulkhead nut, bulkhead nut & washer on the female connector.
- Our standard RP-SMA-female connector (threaded part) length is 3/8 inches. We have a more extended option, 14.5mm, which is available. The longer 14.5mm option has an O-ring embedded in the flange to waterproof the port where the cable enters a network enclosure.

Compatibility with wireless standards & applications:
Our RP-SMA extension cables deliver broad compatibility across numerous wireless systems thanks to their wide frequency range (0GHz to 18GHz), low broadband VSWR, and precise 50 Ohm impedance matching. They support all current WiFi standards at 2.4GHz and 8GHz, including Wi-Fi HaLow 802.11AH, 802.11AX, 802.11AC, 802.11N, 802.11G, 802.11B, and 802.11A. These cables are also ideal for cellular technologies such as LTE / 4G, GSM / 3G, and WiMax—covering both voice and data needs. Additionally, they are well-suited for IoT, automation, and Machine to Machine (M2M) applications like Bluetooth, ZigBee, WiFi HaLow, RFID, LoRa, LTE-m, and NB-IoT, WiFi 6, WiFi 6E. For Helium network deployments in North America, our cables—including all antenna cables and adapters with RP-SMA-male connectors—are fully compatible with Bobcat miners, Sensecap miners, and all Helium LongFi devices.
ROHS 3 and REACH: Our antenna cables comply with ROHS 3 and REACH restrictions on lead content, 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. Installing our RP-SMA male-to-female extension cable is a breeze: The RP-SMA male connector effortlessly fits the jack on most WiFi routers, while the RP-SMA female connector snugly attaches to the male connector on antennas with an RP-SMA male connector. This straightforward installation ensures that your WiFi setup is up and running quickly, giving you peace of mind and confidence in your purchase. Plus, the extension cable allows you to position the antenna further from the router, optimizing.
