3 Meter CNT-400: The Performance Upgrade
For radio frequencies in Wi-Fi (2.4/5 GHz) and LoRaWAN (868 MHz), every decibel counts. Thin standard cables often swallow valuable signal strength. The 3m CNT-400 cable solves this problem. It meets the specifications of the well-known LMR-400 and offers excellent conductivity with minimal attenuation thanks to its large diameter (approx. 10mm).
Specialist for Helium Miners (LoRaWAN)
This cable is the perfect choice for Helium mining setups.
* The Connection: Most miners (Bobcat 300, SenseCAP M1, Nebra, etc.) have an RP-SMA port. Professional LoRa outdoor Antennas, however, have an N-connection.
* No Adapter: This cable connects both devices directly. This not only saves money on adapters but also prevents the attenuation losses that every additional adapter brings.
* More Witnessing: Due to the extremely low attenuation at 3 meters length, almost the full power of the Antenna reaches the miner.
Wi-Fi Range Extension
This configuration is also standard for Wi-Fi applications. Screw the RP-SMA connector to your router or access point (e.g., Asus, TP-Link, various models with external ports) and connect it to a powerful directional or omnidirectional Antenna outdoors (N-connection).
Note on Flexibility
The CNT-400 is a pro cable with a diameter of approx. 10mm and a solid inner conductor. It is rigid and significantly stiffer than thin included cables.
Please plan for appropriate bending radii. It is not suitable for laying "sharply around corners". In return, it offers signal quality that thinner cables cannot achieve.
