Antenna Cable Configurator | RF-240, Low Loss, Weatherproof | Custom Made

If you want to get the maximum out of your connection, our RF-240 coaxial antenna cable is the right choice. This high-performance coaxial cable is perfect as a powerful antenna cable for applications up to 6 GHz. Whether as a Wi-Fi antenna cable for 2.4 GHz and 5 GHz networks or as a high-quality feed line for your 5G or 4G antenna. Customize your cable now in the configurator.


Highlights

  • High-end antenna cable: Extremely low attenuation due to a solid inner conductor – optimized for frequencies up to 6 GHz.
  • For 5G and LTE, 2.4 and 5 GHz Wi-Fi: Perfect as an LTE or 5G antenna cable or for modern dual-band Wi-Fi, where standard cables lose too much signal.
  • Maximum range: Due to low attenuation, it can be used as a long antenna cable to bring the signal from the roof to the router without loss.
  • Solid copper core: Ensures best conductivity (Note: The RF-240 antenna cable is therefore stiffer than the flexible H-155 antenna cable).
  • Custom assembly: We manufacture your cable with centimeter precision using the connectors of your choice (SMA, N, RP-SMA, TNC, etc.).

Your High-Performance Antenna Cable for 5G, LTE, and WiFi

With high frequencies and long distances, every detail counts. The RF-240 was developed to transmit signals with minimal loss. It is your best option if you are looking for a high-performance 4G / 5G antenna cable or need to extend your Wi-Fi antenna cable.

Why this cable for 5G, 4G and WiFi?
The higher the frequency (e.g., 5 GHz Wi-Fi or 3.6 GHz for 5G), the more standard cables "swallow" the signal. The RF-240 counteracts this: Thanks to its solid inner conductor (1.42 mm Solid Copper), it conducts signals significantly better than flexible stranded cables.

Honest advice: Due to the solid core, this antenna cable is slightly stiffer and has a larger bending radius (50 mm) than our H-155. In return, you get maximum performance at the antenna connector.

Configurator: Your Antenna Cable Made to Measure
Whether N-plug for the outdoor antenna or SMA for the router: Simply select your desired length and the appropriate connectors above. We manufacture your cable precisely by hand in our workshop.

Need help choosing the right connector?
Don't know exactly which connector fits your 5G router or Access Point? That's completely normal with so many designations! Simply contact us before ordering. We are happy to help you find the right antenna cable with the matching connectors.

Important Note on Right of Withdrawal:
Please note that this antenna cable is manufactured specifically according to your specifications (length & connectors). Therefore, this item is excluded from the statutory right of withdrawal/return.

High quality, works perfectly and, above all, extremely fast delivery.

Good workmanship
5 from 5

Impeccable workmanship, high-quality materials, and a perfect fit!

Despite its low-loss design, the cable is still so thin that it's relatively easy to route. It's semi-flexible and can be easily bent around corners and edges (within its bending radius).

Very good build quality

The custom-made cable was delivered very quickly. Production was completed the very next business day. The quality of the workmanship, and of course the cable itself, is excellent. I would gladly order again.
