Your Professional-Quality Connection
No more compromises with your Antenna cables. With this RP-SMA connector, you take quality into your own hands. It's the perfect choice if you want to assemble a low-loss Antenna Cable yourself. Whether for an external WiFi Antenna, a LoRa / Helium Antennas application, or other radio projects – this connector ensures a clean and technically flawless connection to your devices. It was specifically developed for common 5.4mm Coaxial cables like H-155, RF-240, or Aircell 5 and fits perfectly.
Maximum Performance for Your Signal
In high-frequency technology, every detail counts. This high-quality 50 Ohm RP-SMA connector is specified for frequencies up to 6 GHz, making it perfectly equipped for modern standards like Wi-Fi 6. The precise adherence to the 50-Ohm impedance minimizes signal reflections (Return Loss) and ensures that the full power of your Antenna truly arrives where it's needed. The gold-plated contacts and the PTFE (Teflon) insulator also contribute to low-loss transmission.
Stable and Reliable: Crimp Technology
Forget wobbly connections. This connector is assembled using a crimping process. This means the outer conductor (Cable shield) is firmly and permanently pressed onto the connector body with a special crimping tool. The result is an extremely tensile and mechanically stable connection that lasts even with Cable movement. Please note: A suitable crimping tool is absolutely necessary for professional assembly. Only then can you ensure you get the full performance from your cable when you want to crimp the RP-SMA connector for H-155 Cable.
RP-SMA vs. SMA: What You Need to Know
Pay close attention to the connection on your device! RP-SMA stands for "Reverse Polarity SMA." The special feature is the reversed inner conductor: The plug has a female sleeve, while the jack on the device has the male pin. This standard was introduced to prevent confusion and is common on most WiFi Routers and Antennas for the consumer market. So, before purchasing, check if you see a small pin in your router's jack – if so, this connector is exactly right for you.

Frequently Asked Questions (FAQ)
Do I need special tools to assemble this connector?
Yes, absolutely! Since this is a crimp connector, you'll need a suitable crimping tool for coaxial cables. Only with this can you securely and firmly crimp your cable's shield to the connector. A soldering iron is usually also needed for your cable's inner conductor. This ensures a reliable connection for your Network Cabling.
What does RP-SMA mean and does the connector fit my WiFi Router?
RP-SMA stands for 'Reverse Polarity SMA'. The key is inside: our Coaxial Connector has a sleeve (female), while the corresponding jack has a pin (male) – exactly opposite to the standard SMA. Most WiFi Routers and home WiFi Antennas use this exact RP-SMA connection. To be sure, just check your device: if you see a small pin in the router's jack, then this connector is perfect for you.
Can I extend my Antenna Cable with this connector?
Not directly. This Coaxial Connector alone is not an extension. It's designed to provide a suitable coaxial cable like H-155 or RF-240 with a professional connection. To build an extension cable, you'll need a piece of Antenna Cable and two suitable connectors – for example, this one for one end and a matching jack for the other.
Is this RP-SMA connector weatherproof for outdoor use?
The Coaxial Connector is made of robust, corrosion-resistant materials. For 100% weather protection outdoors, however, you should additionally secure the finished connection. It's best to tightly wrap it with self-vulcanizing sealing tape. This prevents moisture from entering your Antenna Cable or the connector, enhancing the durability of your Mounting Systems.
Does the connector also fit my RG58 cable?
Unfortunately, no. This Coaxial Connector is specifically made for cables with an outer diameter of 5.4 mm, such as H-155, RF-240, or Aircell 5. An RG58 cable is slightly thinner. Even if you managed to attach it somehow, the connection wouldn't be stable, and the signal quality would suffer. Always use the exactly matching connector for your Antenna Cables.
Does this connector degrade my antenna's signal quality?
Don't worry! While every Coaxial Connector has a tiny, theoretical attenuation, this one is professional-grade. It's optimized for frequencies up to 6 GHz and has extremely low signal loss when properly assembled. If you install it correctly, you won't notice any difference in the performance of your WiFi Antennas.
