End the Connector Chaos: Your Universal Connection
Finally, everything fits together. This Coaxial Adapter is the simple yet professional solution to a common problem: your high-gain Antenna has an RP-SMA Coaxial Connector, but your WiFi Router, Helium miner, or SDR receiver has a standard SMA jack. Instead of searching for new Coaxial cables or Antennas, with this RP-SMA to SMA Coaxial Adapter, you can create a perfect, stable, and electrically sound connection in seconds. Make your devices from various manufacturers effortlessly compatible.
Quality You Can Measure: Focus on Signal Integrity
In high-frequency technology, every detail counts. That's why this Coaxial Adapter is made only from first-class components. The gold-plated inner conductors made of a beryllium copper alloy ensure minimal contact resistance and protect against oxidation. The PTFE (Teflon®) dielectric guarantees excellent insulation properties over a vast frequency range. The result is extremely low signal attenuation (under 0.2 dB) and an excellent Standing Wave Ratio (VSWR), meaning your signal arrives clean and strong where it's supposed to.
The Bodyguard for Your Device Jack
Frequent changing of Antennas can put significant strain on the jack soldered into your device. Repair is often expensive and complex. This Coaxial Adapter acts as a clever shield. It's screwed on once and then absorbs all mechanical wear. Should something wear out after hundreds of mating cycles, you simply replace the inexpensive Coaxial Adapter – not your expensive end device. A small investment that quickly pays off.
One Coaxial Adapter for All Cases: From WiFi to IoT
Thanks to its 50-Ohm specification and wide frequency range extending well beyond 6 GHz, this Coaxial Adapter is a true multi-talent. It's not only the perfect choice for your WiFi setup, but also fully suitable for demanding 5G Antennas or IoT applications like LoRa / Helium Antennas. Whether you're optimizing your home Network, building an IoT gateway, or performing measurements in the lab – this Coaxial Adapter consistently delivers reliable performance.
Strengths & Notes at a Glance
- Pro: Quickly and reliably solves the common compatibility problem between RP-SMA and SMA Coaxial Connectors.
- Pro: High-quality materials like gold, brass, and PTFE ensure low-loss signal transmission.
- Pro: Protects the device jack during frequent Antenna changes and acts as a cost-effective wear part.
- Pro: Robust construction ensures durability and resistance to corrosion.
- Note: The Coaxial Adapter extends the connection, which can lead to leverage on the device jack with heavy Antennas.
- Note: Every plug connection is a potential, albeit minimal here, source of signal loss.

Frequently Asked Questions (FAQ)
Will this adapter fit if my router has a connector with a pin in the middle?
No, then you need the exact opposite version. Your Router has an SMA female connector (with a pin), and this adapter also has an SMA female connector. You cannot connect two female connectors. Look for an adapter with an SMA male connector and always check the thread and the center conductor!
What does 'Reverse Polarity' (RP) in RP-SMA actually mean for me?
Think of it simply: 'Reverse Polarity' means that the internal structure of the connector is reversed compared to standard SMA. A normal SMA male connector has a pin, while an RP-SMA male connector has a hole in the same spot. So, for RP-SMA, the terms 'male' or 'female' refer only to the screw thread, not to the center contact.
Will I lose signal strength or speed due to the adapter?
Don't worry! Technically, every connection adds a tiny amount of signal attenuation. However, with this high-quality adapter, the loss is so extremely small (under 0.2 dB) that you absolutely won't notice it during normal operation with your WiFi or mobile Network. Your speed will remain unaffected.
Can I also use the adapter for my 5G Antennas or for LoRaWAN?
Yes, absolutely! The adapter is designed for a 50 Ohm impedance and covers a frequency range up to at least 6 GHz. This makes it perfect for all your common mobile communication standards like 4G and 5G, as well as for M2M / IoT Antennas such as LoRa / Helium Antennas, as long as the connectors fit.
Why are there even two different standards like SMA and RP-SMA?
Good question! RP-SMA was originally introduced to prevent you, as an end-user, from accidentally connecting unauthorized, extremely powerful Antennas to your WiFi Routers, thereby exceeding legal limits. Technically, however, there's no performance difference – both standards are equally good for you.
Do I need to tighten the adapter with pliers or a tool?
No, absolutely not! Please always tighten the adapter hand-tight only. If you use a tool, too much force can permanently damage both the adapter and the connector on your device. This applies to all Antenna Mounting Accessories.
