Perfect Hold and Optimal Signals: Your SMA Crimp Connector
No more shaky connections and signal interruptions. This SMA connector was developed for a permanently secure connection. The precise screw mechanism ensures that your Antenna Cable remains firmly and securely seated even with vibrations or mechanical stress. Crimp assembly is the professional method for creating an electrically perfect and tensile connection that is in no way inferior to a soldered connection in terms of reliability.
For H-155, RF-240, and More: Maximum Compatibility
This connector is the specialist for common Coaxial cables with an outer diameter of approx. 5.4 mm. It's the ideal choice if you want to crimp a high-quality SMA Connector H-155 Cable. It's also perfectly suited for Cable types like RF-5, RF-240, LMR-240, Aircell 5, or Hyperflex 5. This keeps you flexible and allows you to realize your projects with the best cables without compromising on connection technology.
Standard SMA vs. RP-SMA: What You Need to Know
Pay close attention to the details! This is a standard SMA Male Connector. This means it has the characteristic golden pin (inner conductor) in the center. However, many WiFi devices like WiFi Routers or WiFi Access Points use RP-SMA (Reverse Polarity) connectors, which look identical externally but have a socket instead of a pin. So, before purchasing, be sure to check the connection on your device to avoid damage. If your device has a small hole for the pin, you're in the right place.
The Right Assembly: Why a Crimp Tool is Crucial
For a perfect result, the right tool is essential. Please do not attempt to attach this connector with combination pliers or similar. Only a suitable crimp tool ensures that the connector is fixed evenly and with the correct pressure onto the Cable. The result is a clean, mechanically stable, and electrically superior connection. A professional 50 Ohm Crimp Connector for RF-240 Antenna cables also deserves professional assembly.

Frequently Asked Questions (FAQ)
Do I need a soldering iron to attach this SMA connector?
No, absolutely not! This connector is a 'crimp type'. You'll need a special crimping tool to professionally and securely connect the connector to your cable. Crimping ensures a stable and electrically sound connection for your Antennas.
Will this connector also fit my standard WiFi Router Antenna Cable?
Caution! Many WiFi Routers and WiFi Access Points use RP-SMA connectors, which have a different design. This connector is a standard SMA connector with an inner pin. Please check the port on your device very carefully: If you see a small hole there, this connector will fit. If you see a pin, you'll need an RP-SMA connector.
I have an LMR-240 Cable. Is this connector suitable for it?
Yes, absolutely. The connector is explicitly designed for Antenna Cables like H-155, RF-240, and also LMR-240. It's important that the outer diameter of your cable is approximately 5.4 mm; then it will fit perfectly.
What does '50 Ohm' mean, and is it important for me?
Yes, it's extremely important! The 50 Ohm refers to the characteristic impedance. Nearly all common radio applications, such as WiFi and 4G / LTE Routers, are based on a 50-Ohm system. You must ensure that your Antenna Cables and the connected device also have 50 Ohms to avoid signal loss.
Can I also use the connector outdoors for an Antenna?
The connector itself is not declared waterproof. For outdoor use with your Antennas, you absolutely must protect the connection from moisture after installation. Self-amalgamating insulating tape or a suitable heat shrink tube is best for this.
The connector is described as 'male'. How exactly do I recognize that?
It's simple: Your 'male' standard SMA connector always has the large coupling nut for screwing and a small, golden pin in the center. The 'female' counterpart accordingly has an external thread and a hole for the pin.
