Your Bridge for a Strong Signal: The RP-SMA Cable Extension
Sometimes, only a small piece is missing for perfect reception. With this RP-SMA Female to Female Adapter, you can bridge missing distances quickly and easily. Instead of buying a completely new, long, and expensive Cable, you simply connect two existing Antenna cables with RP-SMA connectors. This is not only smart and cost-saving but also gives you the flexibility to adapt your setup at any time – whether on your WiFi Router, FPV drone, or in the measurement lab.
No Compromises on Quality: Construction and Materials
An adapter is only as good as its internal values. That's why we rely on quality you can measure. The gold-plated brass housing not only protects against corrosion but also ensures excellent conductivity together with the gold-plated beryllium copper contacts. The PTFE (Teflon) insulator guarantees clean separation and contributes to the precise adherence to the 50 Ohm impedance. The result: extremely low signal loss of only approx. 0.5 dB and an excellent VSWR value of less than 1.35:1 for minimal signal reflections.
RP-SMA vs. SMA: The Small Difference That Decides Everything
Caution, risk of confusion! Although RP-SMA and SMA connectors fit mechanically, they are not electrically compatible. The crucial difference lies in 'Reverse Polarity'. With this RP-SMA Coaxial Adapter, the female connector (with external thread) has a central pin. A standard SMA female connector would have a hole here. So please check exactly which connections your devices and Cabling have to ensure flawless function and avoid damage. This Coaxial Adapter is the perfect WiFi Antenna cables connecting coupler for all RP-SMA systems.
Versatile: From Home Network to Drone Technology
The application areas for this Coaxial Adapter are enormously diverse. Wherever a reliable high-frequency connection is needed, it demonstrates its strengths. It is the ideal choice for extending Antenna cables for WiFi Routers and WiFi Access Points (2.4 GHz Components & 5 GHz Components), for connecting components in FPV technology, for M2M / IoT Antennas applications with external Antennas, or even in a professional environment for measurement and test setups. A small but indispensable accessory for every tech kit.
Strengths & Notes at a Glance
- Pro: Enables easy and quick extension of two Antenna Cables with RP-SMA connectors.
- Pro: High-quality materials such as gold-plated contacts and PTFE dielectric ensure low-loss signal transmission.
- Pro: Robust and durable construction for up to 500 mating cycles, ideal for frequently changing setups.
- Pro: Universally compatible with a variety of devices such as WiFi Routers, FPV drones, and M2M / IoT Antennas.
- Note: Each additional connection in the signal path adds minimal attenuation (approx. 0.5 dB), which can be relevant for extremely weak signals.
- Note: The rigid Coaxial Adapter can exert leverage on the device's female connector with heavy cables. Ensure a strain-relieved installation.

Frequently Asked Questions (FAQ)
What exactly do you need an adapter with two RP-SMA jacks for?
You use this adapter, also called a coupler, to connect two Antenna Cables that both have an RP-SMA plug. Think of it like an extension Cable: you simply plug in your cables from both sides, bridging a greater distance to your antenna or device. This is useful for extending your WiFi Antenna Cables or 4G / 5G Antenna Cables.
Are RP-SMA and SMA the same? Can I simply connect them?
No, absolutely not! Although they look almost identical, they are not compatible. The crucial difference is the reversed center pin on RP-SMA. An RP-SMA jack has a pin where a normal SMA jack would have a hole. If you connect them, you'll get no contact or even damage the connectors. So always check exactly what you need for your WiFi Antennas or 4G / 5G Outdoor Antennas!
Does this small adapter degrade my WiFi signal?
Technically, every connection adds a tiny loss; with this adapter, it's only about 0.5 decibels. In 99% of cases, you won't notice it at all. Only if your signal is already extremely weak might this minimal loss play a role. However, for normal use with your WiFi Routers or WiFi Access Points, it's completely harmless.
Can I connect an antenna directly to my router with this adapter?
No, you cannot connect an antenna directly with it. The adapter is designed to connect two cables with RP-SMA plugs to extend the cable *to* the antenna. Most WiFi Antennas or 4G / 5G Outdoor Antennas themselves have a plug and no suitable connection for this adapter.
The adapter is gold-plated. Does that really make a difference?
Yes, it makes a real technical difference! Gold is a fantastic conductor and does not rust. This ensures permanently clean signal transmission with minimal loss, even if you frequently connect and disconnect the adapter. So, it's not just about aesthetics but a quality feature for your Antenna Cables and Coaxial Connectors.
Can I also use the adapter outdoors for my outdoor antenna?
This adapter is not explicitly designated as waterproof. If you use it outdoors for your 4G / 5G Outdoor Antennas or 5G Antennas / Outdoor Antennas, you should definitely seal the connection with self-amalgamating insulating tape or a weather protection boot. This prevents moisture from entering and disturbing your signal.
