Utilise the Proper Coaxial Cablevision
It'southward important to install the proper cablevision. RG-6 ('RG' is an old military term for Radio Guide/Grade) is the manufacture standard, but at that place are other considerations. Apply this chart to help determine which cable is best for the job.

Coil Out Coaxial Cable
If you lay a spool of cable on its side and start pulling cablevision off it, the cable will twist equally information technology unravels, and a twisted cable kinks when you pull on it. Information technology'southward best to slide a department of conduit through the center of the spool and residual it on a ladder. Secure the conduit with a fleck piece of wire.

Avoid Abrupt Bends with Coaxial Cable
Precipitous bends volition damage a cablevision. Think of wrapping a cablevision effectually a coffee can; coaxial cable should never be bent sharper than that. Use a ninety-degree adapter when a sharp curve is unavoidable, like behind a TV stand. Just make sure the connector is rated to handle Hi-Def if that'due south the signal you lot're working with.
4 / 22
Avoid Coaxial Cable Stingers
In one case coaxial cable has been stripped, exit the foil in place, but peel dorsum the braid. Make certain that not even one of the tiny wires of the braid touches the center conductor. That'south what the pros telephone call a "stinger," and stingers are notorious for wreaking havoc with bespeak quality.
5 / 22
Use a Coaxial Cable Stripping Tool
It's non impossible to strip a coaxial cable with a utility pocketknife, only it's not easy. A $15 stripping tool gives you fast and perfect results every time. Coaxial cable strippers have two blades: I blade cuts through the jacket without damaging the braid, and the other blade cuts through everything except the center conductor. Some pros prefer to exit the center usher a scrap long and trim it down (about ane/8 in. by the connector) after the connector is crimped on.
6 / 22
Use Coaxial Cable Compression Connectors
Avoid push-on, screw-on and crimp-on coaxial cablevision connectors; compression connectors work best. You lot'll need a $xv crimping tool to install pinch connectors. Buy coaxial cable connectors that can handle the highest frequency bachelor. Some cheap coaxial cable connectors may piece of work for a security camera, but non a Hi-Def TV or Internet indicate. The aforementioned goes for wall plates. Not all wall plates have born coaxial cable connectors capable of treatment high-cease signals. When in dubiousness, purchase the connector with the highest frequency rating. The rating should exist displayed on the packaging.

Bail Coaxial Cable
Fifty-fifty if your Hi-Def TV is working fine, you might want to cheque to see that the coaxial cable is "bonded" to the house's grounding system. Bonding just ways connecting two things to ensure electrical continuity and conductivity. In a home, it'due south important that the electrical system, communication systems, metallic plumbing pipes, metal gas piping and other metallic systems exist electrically bonded together.
Electrically bonding diverse systems together limits the different voltage potential (pressure) and shock hazards that could be nowadays during a lightning strike or other electrical anomaly. A difference in voltage potential can create strong currents that tin can jump betwixt ii different systems through an undesirable path, and that path could be you!.
The simplest way to bond your coaxial cable to the rest of the business firm is to run the cables through a grounding block, and so run a wire from the cake to the grounding electrode (footing rod) or other qualifying grounding connection point. If y'all accept no idea where any part of the home's grounding organisation is, telephone call an electrician. In addition to electrocution, improperly grounded cables could pb to damaged electronics and house fires.

Brand a Drip Loop in Coaxial Cablevision
Exterior coaxial cable should never run sideways or downward and directly into your house. Rainwater will adhere to the cable and follow it right into your habitation. Loop the cable before it enters the building. The loop will non only help shed the water but also provide actress cable for futurity work or repairs.
A feed-through bushing will allow you to drill a slightly larger hole so y'all can fish the cable through the wall without dissentious it. Dab silicone caulk backside the bushing before pushing it into its concluding resting place. Secure cables with clamps or straps that are held in place with screws. Avoid cablevision straps or hangers that require nails or staples. The chances are proficient that you'll eventually miss the nail on the strap and whack the cable with your hammer by accident. A cablevision that's been crushed past a hammer is a cable that will decadent a bespeak. Straps with the screws already in identify are favored by pros.
ix / 22
Install a Low-Voltage Box for Coaxial Cablevision
It's much easier to fish a coaxial cable through a low-voltage box (sometimes called a "mud ring") than through a regular electric box. But that's not the merely reason to utilise them. Low-voltage boxes let you to push the extra length of wires into the wall cavity without over bending them. You'll damage the cable if you lot try to cram it into a pocket-sized electrical box. Get out 8 to x in. of actress cable in the wall cavity simply in case yous desire to make changes downwardly the route.
10 / 22
Make Good Coaxial Cable Connections
You won't get a good connexion if the dielectric portion of the coaxial able isn't pushed flush with the connector. If information technology's really hard to do, y'all may accept the wrong connector for the cable you're working with. RG-59, RG-6 and RG-6 Quad all require dissimilar connectors.
11 / 22
Run Coaxial Cables Perpendicular to Electric Cables
Go on coaxial cables abroad from electrical cables. Electrical cables that run parallel with a coaxial cable can interfere with your signal. It'due south OK, yet, to run coaxial cables perpendicular to electrical cables.
12 / 22
Purchase Quad-Shield Coaxial Cable
Shielding is what counts when it comes to coaxial cable quality. It blocks interference and keeps the bespeak clean. Skip the economic system cable and go right for the "quad-shield" production. Quad-shield costs twice as much as cable labeled "dual" or "double-shield." But subsequently spending big bucks on your TV or reckoner, skimping on coax merely doesn't make sense.
High-quality cable has ii layers of metal foil and two layers of braided wire to block interference.
Economy cable has only one layer of metallic foil and braided wire.
13 / 22
Cut Coaxial Cablevision Carefully
The signal carried by the coaxial cablevision center wire actually travels along the outside of the wire, not through the inside. So a tiny nick in the wire can cause a large obstruction for the signal. That's why a special coaxial cable stripper (sold at home centers) is the only tool y'all should utilize to prepare the ends of the cable for connectors. Never employ standard wire strippers or a knife. A coax cablevision stripper cleanly cuts the outer jacket, the shielding and the foam jacket in 1 step—without harming the center wire.
xiv / 22
Don't Kink the Cablevision
The wire at the centre of coaxial cable is molded inside a foam jacket to keep it away from the shielding and to block interference. If you lot kink the cable or curve information technology around a sharp corner, you crush the foam. At that betoken, the harm is done and there'south no fashion to undo it. Never bend cablevision effectually a radius smaller than 3 in.
When coax cablevision kinks, the eye wire crushes its foam jacket and gets too close to the shielding. That leads to interference.
15 / 22
Don't Pull Besides Hard
Coaxial cable is delicate, and kinking and crushing aren't the but means to damage the foam jacket surrounding the heart wire. Pulling coax cable too difficult tightens the braided wire shielding and compresses the foam (the way 'Chinese handcuffs' tighten around your finger). That harms indicate quality. The maximum pulling force for RG-half-dozen cable is 35 lbs. Make several short pulls through walls and ceilings instead of a long tug-of-war pull.
sixteen / 22
Don't Run Coax Too Close to Electrical Wiring
Electrical lines can cause nasty interference in coaxial cablevision. So keep coax cables every bit least 6 in. away from electrical cable, even if the cables are separated by wood or other building materials. To reduce any chance of trouble from phone lines, install 'twisted pair' or shielded phone wiring. If the coax must cantankerous over an electric line, create a 90-degree intersection.
17 / 22
Don't Crush the Cable
At that place are a few kinds of staples made for coax, and all of them work well—as long every bit you don't drive them in too far. Forced too tightly over the cablevision, they'll crush the foam jacket inside, causing the same trouble as a kink. If you're running lots of coax, buy a special cablevision stapler, which won't trounce the cable. They're available at some home centers or online (search for 'cable stapler'). When using a hammer, don't pound too hard. The staple shouldn't bite into the cable; a loose agree is better than a tight hold.
18 / 22
Don't Permit the Shields Show
The best cable-routing job tin get fouled up if you aren't careful when y'all attach the stop connector. Always fold back the foil and braided shield advisedly before yous attach the connector. A single strand of complect protruding into the connector area tin can ruin the signal. Double-check your work earlier yous crimp or compress the connector.
19 / 22
Don't Use Screw-On Connectors
Solid connections at the ends of coax cable provide a articulate path for the signal to follow. Loose connections weaken the betoken. End coaxial cable connectors that screw on over the outer jacket of cablevision can loosen up over fourth dimension and even fall off. Instead, utilise crimp-ring style coaxial cable connectors and a special crimping tool (sold at home centers), or meliorate still, compression-style connectors. Pinch-type connectors grip cablevision firmly, without burdensome the inner foam jacket as crimp-manner connectors sometimes do.
twenty / 22
Don't Just Finger-Tighten Coaxial Cable Connectors
As with end coaxial cable connectors, the threaded coaxial cablevision connectors on wall jacks, computers and TVs must provide a solid path for the point. About people finger-tighten these connections, simply that just isn't good enough. Instead, using a 7/xvi-in. wrench, plow the nut an extra quarter turn to snug up the connection.
21 / 22
Install Cable Outlet: Don't Utilize Standard Electric Boxes
The sides and back on a standard electrical box force you to bend the cable sharply inside the box, which tin can degrade the signal. Low-voltage boxes let y'all brand a gentle bend because they aren't really boxes at all, only frames that mount on drywall. These boxes are sold at domicile centers and tin likewise be used for phone, speaker and other low-voltage wiring.
22 / 22
Don't Use a Cheap Splitter
Every time you split a Boob tube signal, it gets weaker. Only you take to split the signal of your coaxial cablevision connectors if you want to add a Goggle box. Still, you can avoid poor motion-picture show quality. First, purchase a splitter that can handle the bandwidth needed for high-definition tv set and high-speed Net. If you get poor moving-picture show quality after installing a coax cable splitter for TV and internet, call your cable provider for advice (they may increase your signal strength). You can also install an amplifier to boost the signal coming from your antenna, satellite or cable service. Amplifiers are sold at home centers, electronics stores and online (search for 'TV amplifier'). Simply programme to spend $l or more to get better results. And continue your receipt so you lot can return the amplifier if information technology doesn't assist. Judge a splitter by the numbers. If you take cable service, purchase one labeled '5-1450 MHz.' For satellite TV, look for a high terminate of at least 2200 MHz.
