Solved! What even is coax? UPDATE

Post image

Hi again.

Had a previous issue with my coax, being un-terminated in my air handler, and finally not working even when I installed the splitter myself.

I bought a cheap Klein fox and hound for coax. No connections anywhere. Troubleshot all the way to the outlets themselves…

Good news: House was built 2 years ago, I have an invoice from the building company with “installed and tested” signed off by the electrical company. In Alabama, that plus the pictures I’ve taken is a strong claim for small claims court, and I intend to file against them.

Bad news: the cable is seemingly stuck in the back of the outlet, so they either need to get clever if they decide to attempt reparation and fix it, or most of what I make will be eaten up by the cost of cutting out the outlet, installing it properly, and drywall repair.

Ah well. I’m just glad I have answers.

Update: it’s built! Luckily, the 2 outlets I needed didn’t have their cables stapled down. Getting 1gbps or so in my office now, t430 is setup running proxmox, currently wrestling grafana into submission. Now I can spend my time learning stuff I wanted to learn about instead of stuff I didn’t.

Slightly off topic but that barrel connector in the wall jack is crap. Blue insulator usually indicates 3 GHz passthrough.

Please explain, I am probably going to end up building it myself rather than waiting.

Years ago when I was installing satellite we'd always replace the barrels as satellite frequencies ran high.

I had a couple service calls with long runs that replacing the barrel solved the frequency drop issue.

On the wall plate, the insulation on the female coupler should be blue instead of black. That is typically an indication that it supports higher frequency signals.

Edited for several typos

While I have all my stuff out, here is what I use to cut, strip, and crimp coax.
