If you\u2019re reading this, chances are you\u2019ve just realized your old TV signal is breaking up, your home internet speed is slower than it should be for your streaming plan, or you\u2019re setting up a new security camera system that needs a reliable coaxial connection. As someone who\u2019s spent the last 12 years working with coaxial cables\u2014first as a field tech, now as part of a team supplying these cables to residential installers, small businesses, and DIYers\u2014I can tell you: installing coaxial cable isn\u2019t rocket science, but it\u2019s easy to cut corners that lead to frustrating signal issues down the line. I\u2019ve seen people skip a simple step and end up calling their internet provider for a service call, when the fix was just a better cable installation. Today, I\u2019m walking you through the process I teach every new installer that reaches out to our team, with tips you won\u2019t find in generic online guides. Coaxial Cable<\/a><\/p>\n

<\/p>\n

First, let\u2019s talk about what you need before you even touch a cable. I\u2019ve had customers reach to our supply desk saying \u201cI just need a coaxial cable\u201d and they show up with a random length they bought at the hardware store. That\u2019s a mistake. Coaxial cables aren\u2019t one-size-fits-all. For most residential applications\u2014like connecting a TV to a wall outlet, or a modem to a router\u2014you\u2019ll want a RG-6 cable. RG-59 is thinner, and used for older analog systems, but RG-6 has better shielding, which is non-negotiable for digital signals, 4K streaming, and high-speed internet. Even if you\u2019re working on a smaller project, RG-6 is the way to go; it\u2019s not much more expensive, and it prevents interference from Wi-Fi routers, microwaves, or neighboring devices that can mess with your signal.<\/p>\n

Next, tools. You don\u2019t need a fancy workshop, but grabbing the wrong tool will ruin your day. Skip the cheap wire cutters that come in multi-tool sets\u2014they leave sharp, uneven cuts that damage the cable center conductor. Invest in a pair of flush-cut wire cutters specifically for small gauge wires, and a coaxial cable stripper. A lot of people use a utility knife, and while it\u2019s doable, it\u2019s way too easy to nick the shielding or the dielectric (that foam layer between the center and the shield, which keeps the signal tight). A good stripper has adjustable notches so you can set it to the exact depth you need for RG-6, which makes stripping fast and consistent. You\u2019ll also need F-type connectors\u2014these are the screw-on or crimp connectors that attach to the ends of the cable. Crimp connectors are better than screw-on because they create a tighter, more reliable seal, and they don\u2019t work loose over time, especially if you\u2019re running the cable outdoors. Finally, a crimping tool that matches your F-type connectors\u2014cheap crimpers from big box stores often don\u2019t apply enough pressure, so the connection will be spotty. Trust me, spending a few extra dollars on quality tools saves you from redoing connections.<\/p>\n

Before you start running the cable, plan the route. This is another step people rush, and end up having to pull the cable through a wall or attic twice because they didn\u2019t account for corners or existing wires. The rule of thumb is to keep runs as short as possible\u2014coaxial signals degrade over distance, so if your modem is 20 feet from the wall outlet, don\u2019t run 50 feet of cable just because it\u2019s easier to hide. Also, stay at least 6 inches away from power cables, electrical lines, or speaker wires. Power cables emit electromagnetic interference that will kill your signal, especially for high-frequency digital signals that are used for streaming and internet. If you have to go through walls or ceilings, use a fish tape\u2014a thin, flexible metal or plastic rod that lets you guide the cable through tight spaces. Never force the cable around a sharp corner; that can kink the shield or crack the dielectric, which will ruin the cable even if the ends look fine. If you have to make a turn, use a 90-degree elbow or bend the cable slowly, keeping the radius at least 2 inches to avoid damage.<\/p>\n

Now, the part everyone gets nervous about: stripping the cable and attaching the F-type connector. Let\u2019s break this down step by step, slow and steady. First, cut the cable to length using your flush cutters. Make sure the cut is straight, no frayed ends\u2014if the cut is angled, you\u2019ll have uneven stripping, so take your time here. Next, use the adjustable notch on your stripper to set it for RG-6. The stripper should have markings for different cable types, so find the RG-6 line. Hold the cable steady, insert it into the stripper, and twist the stripper around the cable two or three times. You\u2019ll feel it cut through the outer jacket, but not go all the way through. Don\u2019t twist too hard, or you\u2019ll nick the inner layers. After twisting, gently pull off the outer jacket. You should now see three layers: the outer jacket you just removed, a thin aluminum or copper shielding foil, and braided copper shielding, and the center conductor, which is a solid copper wire.<\/p>\n

Now, you need to prepare the layers to attach the connector. First, fold the braided shielding back over the outer jacket, like a cuff around the cable. Make sure none of the braid strands are touching the center conductor\u2014if they are, that will cause a short circuit, and your signal will be non-existent. Next, take the foil layer and fold it back too, tucking it under the braid so it doesn\u2019t stick out. You should now have the center conductor exposed, sticking out about a quarter of an inch, with the braid folded back neatly. If the center conductor is bent or has a kink, carefully straighten it with a pair of small needle nose pliers, but don\u2019t bend it more than necessary\u2014even a slight kink can signal issues.<\/p>\n

Now, slide the F-type crimp connector onto the cable. The center conductor should stick all the way through the small hole in the center of the connector, right up to the end of the connector\u2019s barrel. The braid should be around the barrel, not inside it. If the center conductor is too short, the signal will be weak; if it\u2019s too long, it could touch the back of the connector and cause a short. Adjust it so it\u2019s perfectly positioned, then slide the crimping tool onto the connector. Most crimping tools have a specific slot for F-type connectors, so make sure you\u2019re using the right one. Squeeze the crimping tool firmly until it clicks, which means the crimp is tight enough. Don\u2019t over-crimp, or you\u2019ll damage the connector; don\u2019t under-crimp, or it will come loose. Once the connector is crimped, gently pull on it to make sure it\u2019s firmly attached to the cable\u2014if it wiggles off, you didn\u2019t crimp it enough, and you\u2019ll have to redo the connection.<\/p>\n

Now that your cable is made, it\u2019s time to connect it to your devices. Start with the wall outlet. Most wall plates have a coaxial port, so just screw on the F-type connector (or hand-tighten, don\u2019t use pliers\u2014you\u2019ll strip the threads). Then, run the cable to your modem or TV, connect the other end, and tighten it by hand. Once everything is connected, it\u2019s time to test the signal. If you have a TV, pull up the signal strength menu\u2014most modern TVs will show a percentage for signal quality; anything over 80% is good, below 50% means you have a problem. If you have internet, run a speed test and check against your provider\u2019s advertised speed. If the signal is weak, don\u2019t panic\u2014common issues are a loose connector, a kinked cable, or too much length. If you\u2019re getting interference, double-check that the cable isn\u2019t running near power lines, and make sure the shielding on the cable is intact.<\/p>\n

A few final tips that I\u2019ve learned from 12 years in the field, that no one tells you. First, always leave a little extra cable at each end\u2014don\u2019t pull it tight between wall outlets or devices. Leaving 6 to 12 inches of extra cable gives you room to work if you need to move a device later, and it prevents tension on the connectors, which can cause them to come loose over time. Second, if you\u2019re running cable outdoors, use a gel-filled or direct-burial rated coaxial cable, not the same RG-6 you use indoors. Outdoor cables have extra shielding and a weather-resistant jacket that protects against moisture and UV damage. Third, if you\u2019re not comfortable doing this yourself, don\u2019t force it\u2014we\u2019ve seen too many DIY jobs that end up needing a professional to fix, which costs more than if you\u2019d hired someone in the first place. But for most people, following these steps will give you a solid connection that lasts for years.<\/p>\n
