Two cables, One Solution: Your Perfect RP-SMA Connector
Do you have two Antenna cables, but both are too short? No problem! With the JARFT SMA-01-61-TGG Adapter, you can connect two Coaxial cables with RP-SMA connectors easily and efficiently. Instead of buying a completely new, long Cable, this little helper offers you a flexible and cost-effective solution. Perfect if you need to rearrange your setup or bridge a greater distance without wanting to give up your proven Cables.
Technology that Convinces: Maximum Signal Quality Without Compromise
With high-frequency signals, every detail counts. That's why this WiFi Antenna Cable Extension Adapter is designed for maximum performance. The precisely manufactured, gold-plated inner conductors and the high-quality PTFE dielectric ensure extremely low attenuation of only approx. 0.5 dB. The characteristic impedance is precisely matched to 50 ohms, which minimizes signal reflections and ensures clean transmission up to 6 GHz. This way, the full power of your WiFi signal truly arrives.
What exactly is this RP-SMA Adapter for?
This adapter is a classic gender changer that connects two male RP-SMA connectors (i.e., Cable ends with a coupling nut and a hole in the center). It is the ideal passive Coaxial Accessories for the entire WiFi area, whether for Routers, WiFi Access Points, or PC expansion cards. Important note: Do not confuse it with the standard SMA connector! This adapter is specifically designed for RP-SMA (Reverse Polarity) and will not establish an electrical function when connected to standard SMA.
Installation and Important Application Tips
The application is very simple: Screw both cable ends hand-tight onto the adapter – done. The robust screw connection guarantees a mechanically stable connection. Please note that the rigid Coaxial Adapter RP-SMA Male to Male can exert leverage on device jacks. Therefore, ensure that the connected Cables are well-fixed and do not pull on the adapter. For outdoor use, the adapter is not waterproof and must be protected from moisture with self-vulcanizing sealing tape.
Strengths & Notes at a Glance
- Pro: Ensures low-loss signal transmission with only approx. 0.5 dB attenuation.
- Pro: High-quality materials (gold-plated contacts, nickel-plated brass) for durability and corrosion protection.
- Pro: The screw mechanism offers an extremely stable and vibration-proof connection.
- Pro: Universally compatible with the RP-SMA standard used in most WiFi devices.
- Note: Not compatible with standard SMA connectors. A mix-up leads to a non-functional connection.
- Note: As a rigid connector, careless handling can create leverage on device jacks.

Frequently Asked Questions (FAQ)
Can I extend my WiFi Antenna Cable with this adapter?
Yes, that's exactly what it's for! If you have two Antenna Cables, both with an RP-SMA connector, you can connect them directly and with minimal loss to form a longer cable using this adapter.
Does this adapter also fit my 4G or 5G Router?
Unfortunately, in most cases, no. 4G and 5G devices almost always use the standard SMA connector with a small pin in the middle. This adapter is designed for RP-SMA, the typical WiFi standard. So, it's best to check carefully whether your connector has a hole (RP-SMA) or a pin (SMA).
Can you explain what 'Reverse Polarity' (RP) means for this adapter?
Of course! 'Reverse Polarity' simply describes the construction of the inner conductor. Imagine: A normal SMA connector has a pin inside. With your RP-SMA adapter, there's a socket instead, meaning a small hole. That's the whole trick, and it's now the standard for most WiFi devices.
Will I lose signal strength for my WiFi due to the adapter?
Yes, but only so minimally that you'll barely notice it. Every connection in the signal path has a tiny attenuation. This adapter is extremely low-loss, with approximately 0.5 dB, so your connection quality and speed should remain stable.
Can I also use the adapter outdoors?
The adapter itself is not waterproof. If you want to use it outdoors, you absolutely must protect the entire connection – meaning the adapter and both connectors – completely against rain and moisture with special sealing tape.
What is the advantage of this adapter over a new, longer cable?
Quite simply: flexibility and cost! If you already have two shorter, good cables, this adapter is the perfect and affordable solution to connect them. This way, you don't have to buy a completely new, long cable and can use your existing cables individually again later.
