    5.0 out of 5 stars A simple solution to test existing coax cables
    Reviewed in Canada on November 5, 2024
    鶹 Vine Customer Review of Free Product( What's this? )
    Although I don't make coax cables often, I do sometimes need to test existing coax cabling in my home. My home was built many years before the Internet became commonplace, so it primarily used coax cables for TV service. Sometimes it is too complex to run new Ethernet cabling, so reusing the existing coax cables is very useful. I can use MoCA adapters on each end of an existing coax cable to run Ethernet signals, but it is good to make sure the cable is in good condition, and being able to test the cable adds to a sense of confidence that the cable is working properly. These adapter ends are a very simple and inexpensive way to use popular Ethernet cable testing equipment to verify the proper functioning of my coax cables.

    5.0 out of 5 stars Perfect for tracing coax runs

    I wanted to replace some old coax in my house with ethernet cable but, unfortunately, the cables weren't labelled. This meant that finding where the cables were running was a bit of a chore. These little adapters work perfectly. You plug the RJ-45 end into your network cable tester, then hook the other ends up to coax and if there's connectivity, you get a signal. Incredibly simple, but works perfectly.

    Worked perfectly adapting my coax to Ethernet. Took 10 seconds to hook up to my router. Full 1080p signal. I’m a very happy customer. Great price also.

    I recently had to trace out some coax cables. These made the job so easy. Usually I would clip onto the cable with my tone tester and that could fall off or not make a good connection. With this I can clip it in easily to my tone generator and makes it a breeze.
