Your Custom Fit: Perfect Connections for H-155 & Co.
No more standard lengths! With this SMA Female Connector, you take the assembly of your Antenna cables into your own hands. Whether you need a precise length for your motorhome, a clean installation in the server rack, or a special connection for your IoT project – with this SMA female crimp connector for RF-240 and similar cables, you'll achieve professional results. The crimp method is not only significantly faster than soldering but also ensures a mechanically extremely resilient and electrically reliable connection.
Professional Quality Down to the Last Detail
In high-frequency technology, every detail counts. That's why this SMA Connector for 5mm Coaxial cables relies on proven components: a gold-plated inner conductor pin minimizes contact resistance and protects against corrosion. The PTFE (Teflon) dielectric ensures excellent insulation properties even at high frequencies. The robust housing with the precise ¼-36 thread guarantees not only hundreds of mating cycles but also a vibration-proof connection that holds up even under harsh conditions.
The Right Tool is the Key to Success
To unleash the full potential of this connector, appropriate crimping pliers are essential. Please do not attempt to perform the assembly with combination pliers or similar tools. Only with the correct crimping dies will the connector be pressed evenly and with the right pressure onto the Cable. The result is a clean, strain-resistant, and electrically perfect connection. Remember: a crimped connection is permanent. So work carefully – the result will impress you.
50 Ohm: The Standard for Your Radio Applications
This connector, with its 50 Ohm impedance, is perfectly matched to the world of radio technology. Whether WiFi, 4G, 5G, or LoRaWAN – all components in your Network, from the Antenna to the Cable to the Router, must have the same characteristic impedance. With this SMA-S-H155 component, you ensure that no mismatches occur, which could lead to signal reflections and power losses. Important: Never use this connector for 75-Ohm systems like satellite TV!

Frequently Asked Questions (FAQ)
Do I need a soldering iron to mount this SMA socket?
Not at all! That's the cool thing about this socket: it's a pure crimp-type. So you don't need any soldering equipment, just a suitable crimping tool to quickly and securely attach the socket to your cable. This is great for your Network setup.
Can I also use this socket for my thinner RG174 or thicker RG213 cable?
Unfortunately, no. This socket is a specialist and fits perfectly on cables with an outer diameter of around 5.4 mm, such as H-155 or RF-240. For other cable diameters, like your RG174 or RG213, you'll need a different, precisely fitting socket for your Cabling needs.
What's the deal with 50 Ohm impedance, and is it important for me?
Absolutely! 50 Ohms is the standard characteristic impedance in radio technology, whether it's WiFi or mobile communication (4G / 5G Routers). For your signal to arrive cleanly and without losses, all your components – from the Antennas to the Antenna Cables and this socket – must have 50 Ohms. So with this socket, you're spot on for your project, ensuring optimal performance for your WiFi Antennas or 4G Outdoor Antennas.
Does this SMA socket also work with my SAT cable for the TV?
Please don't try! Your SAT system operates with 75 Ohm impedance, but this socket is designed for 50-Ohm systems like WiFi or mobile communication. If you mix the two, it will lead to massive signal interference and, in the worst case, can even damage your devices. It's crucial for your Network setup to use the correct Coaxial Connectors.
Is the connection waterproof if I use the socket outdoors?
The crimp connection alone is not waterproof. If you plan to use it outdoors, you should definitely protect the connection additionally. Our tip: Wrap it tightly with self-vulcanizing sealing tape and pull a heat shrink tube with inner adhesive over it. This way, your Antenna Cables will be perfectly protected against moisture, especially important for 4G Outdoor Antennas or 5G Antennas / Outdoor Antennas.
How do I know if I need an SMA socket or a plug?
It's simple: Look at your counterpart! This socket here has an external thread and a hole in the middle. It fits a plug that has an internal thread in the coupling nut and a small pin in the middle. This way, you ensure that everything fits together perfectly for your Coaxial Connectors.
