I does work to the 1 GBit level (CAT 6) though. **Q: Are these m23?** A: No **Q: Trying to use this for gen 2 starlink cable on an rv. is there a version that would let you handle the ground wire in addition to the 8 conductors?** A: Not that I know of, but why ground the cable. The modem is grounded and you can ground the dish. I have lightning arresters only internet cable. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for the job *by R***E on 15 June 2026* Easy to use, high quality ### ⭐⭐⭐⭐⭐ They save my system and are durable *by L***E on 3 November 2025* I couldn't him up my surveillance without these i live in Seattle and it rains alot, and i have a hard wired Ethernet system, they keep my connections safe and working for a couple of years now.
