Genuine LMR-400 cable from Times Microwave for extremely low signal loss in high-frequency applications, such as 4G/5G routers, WiFi and microwave radio. The ultra low attenuation of <0.36dB per metre below 6GHz, and <0.13dB below 1GHz means that almost no signal is lost in the cable. The tough PE jacket resists UV and provides excellent durability in harsh environments.
This cable is a great choice as premium leads for our Bluespot Mini 5G antenna, or as leads for our WiFi antennas.
This cable is a direct replacement for RG-8 and other 0.400" / 10mm jacketed low-loss coaxial cables, and is a significant upgrade from RG-58 and RG-174. We recommend this cable for Helium / HNT mining (and other 868Mhz applications), outdoor 4G/5G antennas, and WiFi antenna exceptions as the highest performing cable that's a reasonable thickness and relatively easy to bend.
- Please note that while this is the “ultra flexible” variant, this cable is still quite stiff, intended for permanent installations. You will need appropriate cable support or clips.
- Outdoor connections must be taped with self-amalgamating tape to prevent water entering at the connectors and damaging the cable.
- Made in the UK.
