Your High-End Coaxial Antenna Cable for LTE, 5G, and Wi-Fi
With coaxial antenna cables, a simple rule applies: the thicker the cable, the better the signal arrives. While thin cables are completely sufficient for short distances, you lose valuable power over long distances (e.g., from the high roof to the basement).
Our CNT-400 is the solution to this problem. It is a professional "Low Loss" coaxial cable specially developed to transport signals with extremely low loss over long distances. It plays in the same league as the well-known types H1000, MRC400, or LMR-400.
Brand Quality from CommScope
We use the original CNT-400 from the CommScope brand. It offers absolute top values thanks to its special construction (solid core and foamed insulation). The outer jacket is extremely resistant to sun, rain, heat, and cold – perfect for an installation that should last for the next 20 years.
Individually Assembled for Your Project
In our configurator, we build the cable exactly as you need it. Simply select the connectors that fit your devices:
- N-Male & N-Female: The thick, robust standard for outdoor antennas.
- SMA-Male: The small screw connection for LTE and 5G routers (e.g., Teltonika, FritzBox).
- RP-SMA Male: Especially for Wi-Fi devices and Helium miners (Look for the hole in the pin!).
Important Note on Installation
The CNT-400 is a massive, somewhat stiffer coaxial cable with a diameter of approx. 1 cm. You cannot bend it as tightly as a thin standard cable. Please plan some space for curves during installation (bending radius approx. 3-5 cm) so that the cable does not kink.
Important Note on Right of Withdrawal:
This CNT-400 coaxial antenna cable is individually cut and manufactured for you according to your selection (length & connectors). Please note that it is therefore excluded from the statutory right of withdrawal.
