hey guys chrisfix here today I'm going to show you how to put an F connector at the end of a coax cable I just put in hardwood floors and I painted the walls in my room here and I relocated my coax cable and in order to keep the hole really small that goes into the floor here I cut off the end of the coax cable so I'm gonna show you how to put a new one on because this cable isn't gonna be moved a lot I'm just gonna use a twist on F connector this is what it looks like and just twist right on the cable really simple if you're not moving your cable and unscrewing it and screwing it back in all the time and it's pretty stationary this is a good easy connector to use so here's a cutaway of a coax cable at the core we have a copper core that's where all our data is transferred that's how you get your cable TV next we have our plastic insulator right here that insulates this core from the metal coating on the outside so this metal coating on the outside is what makes coax cable special it prevents electrical noise from causing a problem with the signal here that's why TV companies use coax cable plus it helps prevent electrical noise and interference so your TV signal won't get messed up and then on the outside you have the classic rubber coating that protects the whole wire itself so here are all the tools I'm going to use this just cuts the wire this is a box cutting knife or a straightedge and this is your screw on F connector they do make a special tool that you could use that will cut this really quickly and get it to basically look like that where you have the rubber a little bit of the foil the insulator and then the core with the correct size isn't everything but as usual I'm gonna show you the way you could do it without the special tool this is pretty simple not very complex there's a few things you have to look out for but let's get started so here's the final setup that you want you want a quarter of an inch of that white insulator sticking out don't worry about how much copper wire sticks out we could always trim that later that's not important we want to have about an eighth of an inch of this foil or metal insulator sticking out and then we could screw our F connector in right into the rubber right here so now all you need to do is get a length of cable like this cut all the way around don't worry about for this first section how deep you go cuz we're gonna go all the way through just off the whole thing so that you get your copper wire sticking out remember I said you don't have to worry about how long this copper wire is now if you want to use a ruler at this point you can use a ruler because you're going to need a quarter of an inch and then an eighth of an inch so I'm just gonna cut a quarter of an inch plus an eighth of an inch which is right there so with that marked I'll just take my knife carefully and move it all the way around just cutting through the black wire only once you cut all the way around the black wire only you go there slide it off or cut a little slit down the side here open this wire up just like so so now I'm gonna fold back all these little metal wires that are in here kind of holds the foil down and now with those metal wires folded back I'm gonna cut a quarter of an inch lightly plus you don't want to dig into the plastic just all the way around now we have quarter of an inch of white exposed we have our foil exposed and we'll just curl the wires around the foil now that is the exact setup that you want now we're gonna take our screw on F connector slide it in its like so and just tighten it down we're gonna tighten it down all the way and if you did it correctly that white will sit flush with that rubber gasket that's right there now we just get our clippers leave about a quarter of an inch just sticking out a little bit and you're done nice and simple no special tools required so now we take our coax and connect it to TV in make sure you screw it all the way in till you can't screw anymore and because this is gonna stay there and not be unscrewed and screwed in all the time can I take a pliers just give it an extra turn that I'll just snug it in there good now when you're running your cables you want to try to keep the coax and HDMI cables away from any power cables that plug into the wall because if they plug into the wall they're gonna create an electrical interference and although coax cables are protected you'll get a better TV signal if you keep it away from any electrical wires you can see we got a time so our information through the coax cable is coming through when I turn TV on make sure that your TV set up so that the input is on the cable box then I'm going to turn the cable box on okay now we can see that we have a signal and it looks good I'm gonna change it to an HD channel just make sure that the signal is good and it looks good and that's that hopefully this video was helpful if it was give it a thumbs up also consider
