The easiest way that I have found is if you get one of those toners from Cline do you attach the receiver on one end and take your wand go downstairs and just tap all the coaxial until you get a beep

Just used your method and figured out my issues in less than 5 minutes. Four minutes was spent walking up and down my stairs. LOL Thank you!

I have no words man how simple a trick this is and yet my smooth brain could have never imagined it. Thank you so much for sharing this buddy!

Sometimes the least technological method is the easiest and the cheapest. Great job!!

Genius way of keeping it simple! A low-tech solution to a high-tech problem.

You can also determine the length and integrity of the outlet by using a 75ohm terminator instead of the aluminum foil. A 100’ outlet will read 79ohms as RG6 picks up roughly 1 ohm per 25’ of coaxial cable length.

That's a great idea as well. Not everyone has terminators but if you did that'd be a great method. Thanks for the input.

I was a CATV contractor back in the day, late 80's - early 90's. This is what we used when coming to a large prewired facility, home and/or apartment building with zero identification of the cabling. We took a green LED, inserted the positive (+) lead into an F-81 barrel connector and the negative (-) lead shortened and placed it touching the outside of the connector. Then inserted the LED inside of an RG-6 connector where the dielectric typically resides. Lastly, a short piece of coax cable, a 9-volt battery with the braid connected to the neg (-) of a 9V battery harness , and the stinger (center conductor) of the cable to the pos (+) of the battery harness. Tape the battery to the cable neatly with electrical tape and secure the connections and wrap with tape. Finally, terminate a coax connector to the other end. You then take the battery end of your new tool, snap the battery harness connector to the battery, screw into any faceplate. Then go to the head end and start inserting the unmarked cables into the F-81 end of your new tool. When you select the line with the 9V, the LED lights up.

Good job! When the Cable company came over and hooked me up cable service through my router and modem (using smart TVs) I had a cable connection in every room and they all worked. I had just bought the house and the inspectors checked them. I also had a multiple connector amplifier in my attic where all the cables converged and connected. I even had cable out to my pool area. I could have a tv in any room I wanted. The cable guy CUT all of my cables in the attic. He went to the wall jacks and cut the cables and removed the connectors so there were just holes. He took the amplifier with him when he left. I got crappy service with the cable company and they kept raising the prices every few months. So I bought a large digital antenna. I live in an area where you can get about 25 channels for free via antenna. However, all the cable ends will now have to be repaired and I will have to map all of those cables. You just made the job tenable.

RG6U 75 ohm TV cable has a steel center conductor that is copper coated it's not solid copper.. Now this trick will help you trace down lines to their destinations but it will not show you if the cable is compromised which will affect things like internet service to a modem. Chances are the cables will be fine thopugh but if you have any issues with signal quality then you may need to replace that run or move your equipment to a different jack

Very smart trick 😅

Can I use multimeter to see if the ethernet cable on 1 end links to the coaxial on the other end, I think there is a convertor adapter connecting both of them or else it is split to merge them for PoE except to coaxial - it is an old camera system and I fluked it but can't find the ethernet connection. And on old DVR cameras mostly is coaxial and wondering if this trick would work or another idea would work.
