After many years dealing with telecom (and using other people’s toning tools), I broke down and got a nice Fluke cable tester and tone tool. The tool is a Fluke Networks MT-8200-60A IntelliTone Pro 200 Kit . This started because I have to tone out a bunch of coax cables from the back of the house and I tend to do those things as time allows without anyone else around. The tester has an F connector on it so I can hook up an F connector to N female patch cord to connect coax cables. It also have alligator clips to allow hooking to bare wires or even a jack that will check RJ45/RJ11 connectors. Once I get it on Tuesday I will give it a try and report back.
