In a previous question, I had planned a Cat6 (Ethernet) cable run outside a home, adjacent to a coax run. I was advised against it, and I'm interested in taking that advice.
Now I'm considering running the cable inside an exterior wall. (I mean running it inside a wall which separates the house from the outdoors.) It will go from the basement to the 2nd floor.
- Once installed, is this "safe" in terms of lightning and surge considerations? Does the single wall actually add a significant amount of insulation in addition to the miles of air gap between the house and the clouds?
If it's a reasonable approach...
Does it matter if the cable is shielded or not? If shielded, should the shield be grounded?
What additional protections should I add? Like types and locations of surge protection, etc. I'd like to protect the equipment at both ends, but one is more valuable than the other.
