If only were that simple. My wife and I are both type A pos. If we’re both outside, they will swarm her, and leave me alone. If I’m outside alone, they can be bothersome enough to go back inside.

If I’m not mistaken, 100 meters is the max for cat 5/6 cable without switches or other hardware. There are some good directional antenna options for a wireless solution. And yes, a protective pipe (pvc) would be required. No direct burial.
