Use the Proper Coaxial Cable
It'south important to install the proper cable. RG-6 ('RG' is an one-time military term for Radio Guide/Grade) is the industry standard, but there are other considerations. Employ this nautical chart to help make up one's mind which cable is best for the job.

Roll Out Coaxial Cablevision
If you lot lay a spool of cable on its side and start pulling cablevision off it, the cable will twist every bit it unravels, and a twisted cable kinks when you lot pull on it. Information technology'south all-time to slide a section of conduit through the center of the spool and residual it on a ladder. Secure the conduit with a flake piece of wire.
3 / 22
Avoid Sharp Bends with Coaxial Cable
Sharp bends will impairment a cablevision. Remember of wrapping a cable effectually a coffee can; coaxial cable should never exist bent sharper than that. Use a 90-degree adapter when a sharp bend is unavoidable, similar behind a TV stand up. Simply make sure the connector is rated to handle How-do-you-do-Def if that'due south the indicate you lot're working with.
4 / 22
Avoid Coaxial Cable Stingers
Once coaxial cable has been stripped, leave the foil in identify, but pare back the braid. Make certain that not even one of the tiny wires of the braid touches the center conductor. That'southward what the pros call a "stinger," and stingers are notorious for wreaking havoc with signal quality.
5 / 22
Use a Coaxial Cable Stripping Tool
It'due south non impossible to strip a coaxial cable with a utility knife, only it's not easy. A $15 stripping tool gives you fast and perfect results every time. Coaxial cable strippers have 2 blades: I bract cuts through the jacket without damaging the braid, and the other bract cuts through everything except the center usher. Some pros prefer to go out the eye conductor a scrap long and trim information technology downwardly (about 1/8 in. past the connector) after the connector is crimped on.

Use Coaxial Cablevision Compression Connectors
Avoid push-on, screw-on and crimp-on coaxial cable connectors; pinch connectors work best. You'll need a $xv crimping tool to install compression connectors. Buy coaxial cable connectors that can handle the highest frequency available. Some inexpensive coaxial cablevision connectors may work for a security camera, but not a Hi-Def Tv set or Internet signal. The same goes for wall plates. Not all wall plates have born coaxial cable connectors capable of handling high-stop signals. When in doubt, buy the connector with the highest frequency rating. The rating should be displayed on the packaging.

Bond Coaxial Cable
Even if your Hello-Def TV is working fine, you might want to check to encounter that the coaxial cable is "bonded" to the house'due south grounding system. Bonding just ways connecting ii things to ensure electrical continuity and conductivity. In a habitation, it'southward important that the electric organization, advice systems, metal plumbing pipes, metal gas piping and other metallic systems exist electrically bonded together.
Electrically bonding various systems together limits the different voltage potential (pressure) and shock hazards that could exist present during a lightning strike or other electrical anomaly. A difference in voltage potential can create strong currents that can jump between two unlike systems through an undesirable path, and that path could be you!.
The simplest way to bail your coaxial cable to the remainder of the house is to run the cables through a grounding block, then run a wire from the block to the grounding electrode (footing rod) or other qualifying grounding connection point. If you have no idea where whatever part of the dwelling house'due south grounding arrangement is, telephone call an electrician. In addition to electrocution, improperly grounded cables could lead to damaged electronics and house fires.

Make a Baste Loop in Coaxial Cable
Outside coaxial cable should never run sideways or downward and directly into your business firm. Rainwater will attach to the cable and follow it right into your home. Loop the cable before it enters the edifice. The loop volition non merely aid shed the water just also provide extra cable for future work or repairs.
A feed-through bushing volition allow you lot to drill a slightly larger hole so you can fish the cable through the wall without dissentious it. Dab silicone caulk behind the bushing earlier pushing it into its final resting place. Secure cables with clamps or straps that are held in place with screws. Avoid cable straps or hangers that require nails or staples. The chances are practiced that y'all'll somewhen miss the nail on the strap and whack the cable with your hammer past accident. A cable that'southward been crushed by a hammer is a cable that will decadent a indicate. Straps with the screws already in place are favored by pros.

Install a Depression-Voltage Box for Coaxial Cablevision
It's much easier to fish a coaxial cable through a low-voltage box (sometimes chosen a "mud ring") than through a regular electrical box. But that's non the but reason to use them. Depression-voltage boxes allow you to push the actress length of wires into the wall cavity without over bending them. You lot'll damage the cablevision if yous try to cram information technology into a pocket-size electrical box. Leave 8 to x in. of actress cable in the wall cavity merely in case you want to make changes downward the route.
10 / 22
Make Skillful Coaxial Cable Connections
You won't become a good connexion if the dielectric portion of the coaxial able isn't pushed flush with the connector. If information technology's really difficult to exercise, you may have the wrong connector for the cable yous're working with. RG-59, RG-half dozen and RG-6 Quad all crave different connectors.
11 / 22
Run Coaxial Cables Perpendicular to Electric Cables
Keep coaxial cables away from electric cables. Electric cables that run parallel with a coaxial cable tin interfere with your bespeak. It'south OK, however, to run coaxial cables perpendicular to electrical cables.
12 / 22
Buy 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 economy cablevision and go right for the "quad-shield" production. Quad-shield costs twice as much every bit cablevision labeled "dual" or "double-shield." But subsequently spending big bucks on your Idiot box or computer, skimping on coax only doesn't make sense.
High-quality cablevision has two layers of metallic foil and two layers of braided wire to block interference.
Economic system cable has just 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. And then a tiny nick in the wire can crusade a big obstacle for the indicate. That's why a special coaxial cable stripper (sold at home centers) is the just tool you should use to prepare the ends of the cable for connectors. Never apply standard wire strippers or a knife. A coax cable stripper cleanly cuts the outer jacket, the shielding and the foam jacket in one step—without harming the centre wire.
14 / 22
Don't Kink the Cable
The wire at the center of coaxial cable is molded inside a foam jacket to go along it abroad from the shielding and to block interference. If you kink the cablevision or bend information technology around a precipitous corner, you crush the foam. At that point, the harm is done and at that place's no way to undo it. Never curve cablevision around a radius smaller than iii in.
When coax cable kinks, the middle wire crushes its foam jacket and gets too close to the shielding. That leads to interference.
15 / 22
Don't Pull Also Difficult
Coaxial cablevision is delicate, and kinking and crushing aren't the only means to damage the foam jacket surrounding the center wire. Pulling coax cable besides hard tightens the braided wire shielding and compresses the foam (the way 'Chinese handcuffs' tighten around your finger). That harms signal quality. The maximum pulling forcefulness for RG-6 cablevision is 35 lbs. Brand several short pulls through walls and ceilings instead of a long tug-of-war pull.
16 / 22
Don't Run Coax As well Close to Electric Wiring
Electrical lines tin can cause nasty interference in coaxial cable. So continue coax cables equally least 6 in. away from electrical cable, even if the cables are separated past wood or other building materials. To reduce any run a risk of problem from phone lines, install 'twisted pair' or shielded phone wiring. If the coax must cross over an electrical line, create a xc-degree intersection.
17 / 22
Don't Crush the Cable
In that location are a few kinds of staples made for coax, and all of them work well—as long as you lot don't bulldoze them in too far. Forced besides tightly over the cable, they'll crush the foam jacket within, causing the same problem as a kink. If you lot're running lots of coax, buy a special cable stapler, which won't crush the cable. They're bachelor 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 hold is better than a tight agree.
xviii / 22
Don't Let the Shields Show
The best cable-routing task tin can become fouled up if you aren't careful when you adhere the end connector. Always fold dorsum the foil and braided shield carefully earlier y'all attach the connector. A single strand of braid protruding into the connector area can ruin the bespeak. Double-bank check your work earlier you crimp or compress the connector.
19 / 22
Don't Utilize Spiral-On Connectors
Solid connections at the ends of coax cablevision provide a clear path for the signal to follow. Loose connections weaken the signal. End coaxial cable connectors that screw on over the outer jacket of cable can loosen up over time and even autumn off. Instead, use crimp-ring way coaxial cable connectors and a special crimping tool (sold at domicile centers), or better all the same, pinch-style connectors. Pinch-type connectors grip cable firmly, without crushing the inner foam jacket as crimp-style connectors sometimes exercise.
20 / 22
Don't But Finger-Tighten Coaxial Cablevision Connectors
As with stop coaxial cablevision connectors, the threaded coaxial cable connectors on wall jacks, computers and TVs must provide a solid path for the signal. Most people finger-tighten these connections, but that only isn't good enough. Instead, using a 7/16-in. wrench, turn the nut an extra quarter turn to snug upwardly the connectedness.
21 / 22
Install Cable Outlet: Don't Utilise Standard Electrical Boxes
The sides and back on a standard electrical box force you lot to curve the cable sharply inside the box, which can dethrone the signal. Low-voltage boxes let you brand a gentle bend considering they aren't actually boxes at all, just frames that mount on drywall. These boxes are sold at dwelling house centers and can too be used for phone, speaker and other depression-voltage wiring.
22 / 22
Don't Utilise a Cheap Splitter
Every time you lot divide a TV signal, it gets weaker. Just y'all have to split the bespeak of your coaxial cable connectors if you lot want to add together a TV. Still, you can avoid poor movie quality. First, buy a splitter that tin handle the bandwidth needed for loftier-definition television and high-speed Internet. If you get poor picture quality after installing a coax cablevision splitter for TV and net, phone call your cable provider for advice (they may increase your signal strength). You can as well install an amplifier to heave the bespeak 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 go improve results. And go on your receipt so you can return the amplifier if it doesn't aid. Estimate a splitter by the numbers. If you have cable service, buy one labeled 'five-1450 MHz.' For satellite Goggle box, look for a high end of at to the lowest degree 2200 MHz.
