HD-SDI on old RG-59 cable?! How…. No, why, was this done and why does it actually work?
Some day this will hatch into a beautiful butterfly.
I don’t know how this was wired. I legitimately can’t figure it out. Long handled BNC extraction tools aside, I can’t understand how anyone was actually able to see the back of the router to make the connections.

Seriously, I’m having a great time here, even if my brain does occasionally rattle a bit…
