The Problem Solver for Tight Passages
Anyone who has ever laid an Antenna Cable in a vehicle or through a wall knows the challenge: the bore is barely larger than the Cable itself. A standard connector will never fit through. The FME Jack for H155 cables is the ingenious solution here. Thanks to its extremely small diameter, you can effortlessly route the assembled Cable and only screw on the appropriate Adapter at the destination. This saves time, nerves, and prevents unnecessarily large drill holes.
Maximum Flexibility: The FME System as a Base
FME stands for "For Mobile Equipment" and describes a clever, modular system. This jack serves as a universal base on your cable. Do you need an SMA connection for your 4G Routers? Simply screw on an FME-to-SMA Adapter. Do you need an N-connector for an Outdoor Antenna? No problem, there's a suitable Adapter for that too. You always remain flexible and don't have to assemble a completely new Antenna Cable for every application.
Process-Reliable and Durable: The Crimp Connection
A professional connection is essential for good signal quality. This FME Jack is designed for full crimp assembly. This means that both the inner and outer conductors are firmly and securely pressed onto the connector with a special crimping tool. This method is not only significantly faster than soldering but also creates a mechanically extremely resilient and electrically superior connection with consistently low contact resistance. This way, you avoid signal loss from the start.
Ideal for Mobile Communications and Demanding Installations
With an optimized frequency range up to 2 GHz (often usable up to 3 GHz in practice), this Coaxial Connector is perfect for all common mobile communication applications such as 4G/4G and GSM, as well as for GPS Systems. The vibration-proof screw connection ensures that the connection remains absolutely reliable even with vibrations in the car, truck, or on the boat. If you need a waterproof FME connection for outdoor use, simply protect the screw connection additionally with self-vulcanizing sealing tape.
Strengths & Notes at a Glance
- Pro: Extremely slim design greatly simplifies Cable Routing.
- Pro: Highly flexible system due to a wide selection of screw-on Adapters.
- Pro: Fast and very reliable assembly using Crimp Technology.
- Pro: Vibration-proof screw connection, ideal for mobile use.
- Note: A suitable crimping tool (hex dimensions 6.48 mm / 1.69 mm) is absolutely necessary for assembly.
- Note: For critical applications above 3 GHz (e.g., 5 GHz WiFi), SMA or N-connectors are technically the better choice.

Frequently Asked Questions (FAQ)
Do you need a special tool to attach this FME jack to the cable?
Yes, absolutely! For a clean and stable connection, you'll need a suitable crimping tool. Make sure it has the correct crimp dimensions: 6.48 mm for the outer conductor and 1.69 mm for the inner conductor pin. Without the right tool, you risk a poor connection and signal loss.
Can I also use this jack for my 5 GHz WiFi Antenna cables?
Technically, it's possible, but not ideal. The jack is optimized for frequencies up to 3 GHz, perfect for mobile communication or GPS. In the 5 GHz range of your WiFi Network, you might experience higher signal loss. For the best performance, we recommend using specially designed connectors like SMA or N-type.
Does this FME jack also fit my thinner RG58 cable?
No, unfortunately not. This jack is specifically designed for cables with an outer diameter of approximately 5.4 mm, such as H-155 or RF-240. Your RG58 cable is slightly thinner, so the connection wouldn't be firm and secure. It's always best to choose a jack that is precisely intended for your cable type.
The golden pin in the middle is loose – is my jack broken?
Don't worry, that's absolutely normal and by design! You first crimp the loose pin onto the inner conductor of your cable. Then, you slide the entire assembly into the jack housing until it clicks into place. So, the pin is always a separate part before installation.
What does the abbreviation 'FME' actually stand for?
Is the connection waterproof if I use it outdoors?
The connector alone is not completely waterproof. If you want to use it outdoors in the rain, you should provide additional protection. It's best to use self-amalgamating sealing tape or heat-shrink tubing with internal adhesive to securely seal the connection.
