How to install cable television

These days it is very popular for DIY homeowners to add more cable TV locations in their home, or upgrade Internet service to a cable modem. These are easy for you to do yourself but there are some common mistakes that people make that could result in bad picture quality or intermittent operation.

This section will cover wiring with coaxial cable in your home and help you avoid common mistakes made when installing a CATV location or cable modem in your home.

1) Mistakes made when running coaxial cable.
2) How to install a connector on your cable.
3) Cable TV splitters.
4) How to install the coaxial cable for your cable modem.

Two Basic Mistakes made when running TV coax cable.

This first thing you need to keep in mind when running your cable is not to make hard 90 degree bends with the cable. The bends should be gradual bends; hard bends or kinks in the cable may result in a bad picture or pour performance.

Another mistake is to have too many cable splitters in your home. It is best to run each Cable TV wire back to a central location where the cable company brings your service into the house.

How to properly install a connector.

Improperly installed connectors are also a common mistake when installing coaxial cable. One of the most important things to remember is to make sure you have a good connection with the outer shield of the cable. DO NOT CUT IT OFF! You only need to trim it but make sure you leave enough to make a good connection.

The picture will show you the proper strip out of a coaxial cable for your typical F type crimp on or twist on connector.

Once the cable is stripped out the process is fairly simple, if the connector is a twist type you simply insert the cable into the connector and twist thee connector onto the cable until it is secure. If it is a crimp connector you insert the cable into the connector until the white inner insulation is flush with the small hole inside the connector and use a crimp tool to secure the connector to the cable.

Cable TV splitters.

It is best to have only one splitter unless you have a cable modem, than you will need two. Figure out how many TV locations you will have and purchase a splitter that will accommodate the number of locations you will need. You can find splitters in a wide verity of sizes.

Below is an example of how to wire a cable TV splitter.

How to install cable televisionCable Modems.

If you are going to install the wiring for a cable modem you will need to split the cable where it enters the house and than split it again for your televisions. Not splitting the cable correctly is a common mistake made when installing a modem, the best way is to get a simple two way splitter. It will have 1 in and two outs, bring the incoming cable from your provider into the “IN” position. Next take an “Out” to your modem. Than from the other “Out” take a cable to the “IN” of your second splitter. Connect your TV’s to the “OUTS” on your second splitter.

Below is an example of the first splitter as the cable enters your house.

How to install cable television

Troubleshooting Tips

The first thing you should check is your connectors to insure they are installed properly and securely fastened.

Next make sure you don’t have any kinks or real hard bends in your cable.

Make sure the cable is split properly and that you have the minimum number of splitters in your circuit, preferably no more than two.

Make sure your “IN” and “OUT” on your splitter is correct.

If all else fails replace the cable and redo the connectors.

Remember that less is more, the least amount of cable and splitters you have the better.

Make sure you paid your cable bill. (Just kidding)

Traditional coaxial cables were once the standard means of connecting a television to an antenna or cable TV access point. But they are less common now that high-definition and ultra-high-definition televisions make prevalent use of HDMI, fiber optical, and ethernet cables for many of their connections. Still, coaxial cables have their purposes, and your video system may still use them.

A coaxial cable used to bring electronic signals to a television or other electronic device terminates in an F connector. There are several ways these F connectors can be attached to coaxial cable. Professional installers use a coaxial cable stripper, which strips all three layers of the cable at once. Then, they slip on the F connector and secure it with a coaxial cable tool, which presses the connector onto the cable and crimps it at the same time.

What Is an F Connector?

An F connector is a fitting that connects a coaxial cable to an electronic device or a wall jack.

Watch Now: How to Install F-Connectors on Coaxial Cable

If you’re not a pro, you probably don’t have these special tools. But you might own (or can borrow) a basic cable crimper that will allow you to install a crimp-type F connector. Don’t have a crimper? No problem—simply buy a twist-on F connector, which you can install by hand.

As for stripping the cable before adding the connector, an ordinary utility knife will do the trick. It helps to have standard electrical wire strippers for one of the steps, but you can also do this with the utility knife.

How to install cable television

What You’ll Need

Equipment / Tools

  • Utility knife
  • Wire strippers (optional)
  • Cable crimper (for crimp-style connectors)

Materials

  • Crimp-type or twist-on F connector

Instructions

Strip the Wire

First, you’ll strip 3/4 inch of the black outer jacket from the end of the coaxial cable, using a utility knife.

Carefully make a shallow cut all the way around the cable, cutting through the outer jacket only. Use your fingernails to peel away the jacket from the cable. This exposes the layer of fine metal shielding wires and foil just inside the jacket.

How to install cable television

Trim the Shielding Foil

Fold back the shielding wires onto the cable jacket, and trim them with wire strippers or scissors so they are about 1/8 inch long. Now, use the utility knife to cut through the metal shielding foil so it extends only about 1/4 inch from the cut in the cable jacket. Again, the wires are folded back onto the jacket, while the foil extends 1/4 inch toward the end of the cable.

How to install cable television

Trim the Plastic Layer

Strip 1/4 inch of the white plastic insulating layer from around the copper wire core of the cable, using wire strippers or a utility knife. Be very careful not to cut or nick the copper wire itself, as this can affect the cable’s performance. There should now be 1/4 inch of the bare copper wire extending from the end of the white plastic layer.

How to install cable television

Install the Connector

Crimp-type F connector: Fit the crimp ring of the F connector over the end of the cable so it seats over the outer jacket (and the shielding wires). Slide the other half of the connector onto the cable so it fits into the crimp ring and the white plastic layer makes contact with the hole inside the connector. You should see about 1/4 inch of copper wire inside the end of the F connector. Continue to the final step.

Twist-on F connector: Fit the F connector onto the end of the cable and twist it clockwise until the white plastic layer contacts the hole inside the connector, and the copper wire extends about 1/16 inch beyond the front end of the connector. For twist-on connectors, your work is done.

How to install cable television

Completing a Crimp-Type Installation

On a crimp-type F connector, place the crimping tool jaws over the crimp ring of the F connector, and squeeze the tool handles to secure the connector to the cable. You are now finished.

You’ve got big plans. You’ve recently bought a new flatscreen television and you know exactly where you want it — impressively wall-mounted in your den, free from all electrical cables and wires, for a sleek and modern look. But, as you learn how to choose a tv wall mount and prepare for the task at hand, you realize one consideration you hadn’t yet thought about: where to put a cable box console for your wall-mounted TV?

Wireless technology may be on the rise but, as of now, most setups will still require you to wire your cable box into your new television. While televisions on stands have an easier time concealing wires and offer a number of positions for a cable box, it’s less clear where to put a console with a mounted TV screen. Thankfully, there are several tv mount options available that can accommodate your desired aesthetic, viewing angle, cost, and technology needs!

Floating Wall Mount Underneath The Television

One idea for where to put your cable box is to use shelves that are also wall mounted. These are typically placed below the television and can accommodate multiple devices in a variety of arrangements. Floating wall-mounted cable boxes offer a few specific advantages and disadvantages:

  • Ease of setup – This can often be one of the simplest solutions in terms of setup and overall work involved.
  • Optimal remote communication – Because the boxes are located without obstruction directly below or around the television, there’s less likelihood of the receivers being fickle.
  • Wiring considerations – Having taken the time to mount your television and cable box, the last thing you want is a mess of wires. Thankfully, many wall mounts for media console devices come with cable management clips to hide tv wires .
  • Potential clutter – Because a wall-mounted television offers a pristine look, some might find a wall mount to clutter the area if hiding cords is not feasible. After all, the entire point of mounting the TV is to isolate it and open up space. If that’s the case, you have other options:

    Behind Your Television

    Depending on the type of television and how it’s mounted to your wall, as well as the size of the cable box and the number of other devices you have, you could potentially hang and hide the cable box behind your TV.

    When possible, this approach can offer both a simple setup and an elegant aesthetic. Among other options, you can use cable ties or adhesive hanging strips to attach the cable box and cords to the TV.

    However, many televisions do not offer sufficient space to hide different cable boxes, especially if they are bulkier (such as those with DVR functionalities). Depending on how much tilt for your wall mount tv is desired, this could also factor into the potential capability of concealing the cable box behind the screen. You’ll also want to check to make sure the remote works properly, or consider buying an infrared extender to ensure the signal is not interrupted.

    Entertainment Center / Other Furniture

    For those with numerous devices, sometimes storing their cable box and other media player electronics in an entertainment center, armoire, or other furniture is the best approach. Ideally, the furniture will have pre-cut holes for wires, or you’ll need to add some yourself.

    It’s vital to ensure your electronics have proper ventilation to avoid overheating. Because devices cool off by emitting heat, improperly ventilated furniture can pose a risk to your hardware. The last thing you want is for the cable to go out because your armoire was too stuffy!

    On the downside, putting your cable box and other devices in an entertainment center can present logistical challenges. Because furniture can interfere with remotes’ signals, investing in a universal controller or an infrared receiver kit can often be a wise decision.

    You’ll also need to connect your cable box wires to your television, either by on-wall cable raceways or by running wires through your walls. Just make sure to use the right kit to create an in-wall wiring system, as regular cords should not be threaded behind a wall (it’s actually against the National Electrical Code ). You can also utilize a professional installer if your electronic setup grows in complexity and now requires taking a drill to the wall.

    In Another Room

    While you’re thinking about wiring your wall for optimal aesthetics/functionality, you might also consider another alternative location for your cable box: an entirely different room. The ability to pursue this option will depend on how your home is built and organized but can be a great choice if you have multiple devices but don’t want to clutter a space with an entertainment center.

    Some pros and cons to consider:

  • Clean, flexible visual appearance – With all wires running into another room and no shelves or furniture, this approach provides creative flexibility — design the room as you see fit.
  • Expense profile – Because of its complicated nature, setting up your cable box in another room can be more expensive than other alternatives. Aside from the costs of wiring, you’ll also need to invest in a universal or extended controller.
  • High complexity – This isn’t a straightforward and simple DIY project. In reality, you might have to hire a professional to help you set up the cable box in another room and ensure that the receivers aren’t obstructed.

    Where To Put Cable Box For Wall-Mounted TV?

    As this guide demonstrated, there are a variety of different ways to position your cable box. For some, it might require little more than another shelf installation . But for others, it might be time to get creative.

    How to install cable television

    What to Know

    This article explains how to connect an audio or video source to a television using component video cables. This information applies to televisions from a variety of manufacturers, including LG, Samsung, Panasonic, Sony, and Vizio.

    Connect the Cable to Your Video Source

    How to install cable television

    ” data-caption=”” data-expand=”300″ data-tracking-container=”true” />

    Find the component video and audio outputs on your video source, that is, the device that is going to connect to the TV.

    Note: This demonstration uses one component video cable (with red, green, and blue RCA jacks) and a separate audio cable (with red and white jacks). It’s possible that you have all five jacks on a single RCA cable, but the setup is the exact same.

    The color-coded connectors are your friend. Make sure that green goes to green, blue to blue, and so on.

    Take note that the audio cables are always red and white and that it’s possible for their output plugs to be slightly removed from the blue, green, and red video jacks.

    There are all kinds of options for hiding the wires of your television, each with their strengths and weaknesses. But when you know your television will be on a specific wall for the long term, why not actually hide them inside the wall? Adding cable access brush plates to your wall is easy to do and takes less than 30 minutes.

    How to install cable television

    TV’s should be hung on interior walls (not a Universal rule, but good rule of thumb), which is good for this project because interior walls are often open inside (no insulation) so you can run your cables through the wall easily.

    Step 1: Trace and cut the holes

    How to install cable television

    Place your electrical box on the wall where you want it to end up, and trace around it. Use a stud-finder if necessary to ensure there are no studs in the way. You want to cut your hole about 1/8-3/16 on the inside of that line, to give space for the lip of the electrical box to catch. Do this in a location that will be behind the TV, but not where you will need to put your TV mount. Then repeat the process, adding another box where you want the cables to come out. Make sure it’s somewhere that will be hidden, either down low behind a dresser or credenza, or you can even go through the wall to the room behind if you have that option and it makes sense.

    Step 2: Screw in the electrical box and feed the cable

    How to install cable television

    The great thing about TV cables is you can use the low-voltage electrical box, which is basically completely open into the wall. Screw it in place and run your cables through the wall. I find it a lot easier to run the cables before you add the brush plate. If the second box is directly below the first one, as in our case, simply drop the cable end down and pull it out.

    Step 3: Add the brush plate and close up

    How to install cable television

    Slip the cables through the brush plate and screw it into the electrical box. Then add the plate cover and you’re done!

    How to install cable televisionHow to install cable television

    We’ve done this trick with several of our TVs, and love housing our TV components in a piece of furniture or something that blends naturally into the room. For example, in our bedroom, our dresser.

    How to install cable television

    We drilled a small hole through the back of the dresser and ran all the cables into the top middle drawer. Some components will require quite a bit of ventilation so they don’t overheat (gaming consoles, for example), so wherever they’re stored you’ll want to plan for that. But this is a simple project that you can do with minimal tools and time. And it makes such a big difference in keeping your space looking clean.

    How to install cable television

    Fiber optic cables are set to be the future method of connecting to the Internet as well as providing other beneficial connections for items like televisions or telephones. You can only install fiber optic cables in your home if it’s available in your area. To determine this, you’ll need to contact your local phone company. Where there is fiber optic service available, there will be a distribution box in the neighborhood and another box on a phone pole that shouldn’t be more than a few hundred feet away from your house.

    Step 1 – Run Cable to the House

    Get the cable from the local box to your house. This is something you can’t do yourself. Instead, you’ll need to connect your phone company and a technician will do the work.

    The fiber optic cables will end up in an optical network terminal on the side of your house, in the basement, or in the garage. It’s from here that you’ll run the fiber optical lines into your house for phone, Internet, and TV.

    Step 2 – Check Appliances

    It’s all very well having fiber optic cable in your house, but you also need phones and a set-top box that will work with it. Check your phone’s compatibility with fiber optic connectivity since older models won’t work with fiber optic cable. If they don’t, you’ll need to buy new phones that are compatible with fiber optic technology. Similarly, make sure your set-top box is set up to work with fiber optic cable. If not, contact your cable provider for assistance.

    Step 3 – Run the Cable

    You’re going to need to run fiber optic cable from the optical network terminal into your house where it will meet the network box for your phone. Unless you’re comfortable working with phone terminal connections, you’ll need to employ a qualified phone engineer to take care of the work.

    For your cable, you’ll be establishing a connection from the optical network terminal to your house’s coaxial network. Again, unless you’re very competent, this work should be carried out by a professional.

    Step 4 – Check the Computer

    For your computer, you’ll need to use an RJ-45 wall jack and install a battery back-up for it. Connect from the jack to the computer using an Ethernet cable for the best possible connection. Test for connectivity and make sure all your phone lines are switched over to fiber optic. This will allow you to connect to the Internet properly. You should find that you’re able to upload and download material much faster.

    Step 5 – Hook up Television

    To hook up your television, you’ll need to run a coaxial cable to the set top box. From the box to the TV, use HD or S video cable. If you use HDMI cable to hook up your TV, which you might if you want HD reception, you won’t need to use a separate audio cable. Switch on your television and cable box to check your service is working properly.
