Utilise the Proper Coaxial Cablevision
Information technology's important to install the proper cablevision. RG-6 ('RG' is an old military term for Radio Guide/Grade) is the industry standard, just there are other considerations. Apply this nautical chart to help determine which cable is best for the job.

Roll Out Coaxial Cable
If you lay a spool of cable on its side and start pulling cablevision off it, the cablevision will twist as it unravels, and a twisted cable kinks when you pull on it. It's best to slide a department of conduit through the center of the spool and residue it on a ladder. Secure the conduit with a scrap slice of wire.

Avert Abrupt Bends with Coaxial Cablevision
Abrupt bends volition damage a cablevision. Recall of wrapping a cable around a java tin; coaxial cable should never exist bent sharper than that. Utilise a 90-caste adapter when a sharp bend is unavoidable, like backside a TV stand. Simply make sure the connector is rated to handle Hello-Def if that's the bespeak you're working with.
4 / 22
Avoid Coaxial Cablevision Stingers
Once coaxial cable has been stripped, leave the foil in identify, but skin back the complect. Make certain that not even one of the tiny wires of the braid touches the center conductor. That's what the pros call a "stinger," and stingers are notorious for wreaking havoc with point quality.
5 / 22
Employ a Coaxial Cablevision Stripping Tool
It's not impossible to strip a coaxial cablevision with a utility knife, but information technology'south not easy. A $15 stripping tool gives y'all fast and perfect results every fourth dimension. Coaxial cable strippers take two blades: One blade cuts through the jacket without damaging the complect, and the other blade cuts through everything except the center conductor. Some pros adopt to leave the center conductor a bit long and trim it down (about 1/8 in. by the connector) after the connector is crimped on.
6 / 22
Use Coaxial Cablevision Compression Connectors
Avoid push-on, screw-on and crimp-on coaxial cable connectors; compression connectors work all-time. You'll need a $15 crimping tool to install compression connectors. Buy coaxial cable connectors that tin can handle the highest frequency available. Some cheap coaxial cable connectors may work for a security camera, only not a Hello-Def Tv set or Net signal. The same goes for wall plates. Non all wall plates take built-in coaxial cablevision connectors capable of handling high-end signals. When in dubiousness, buy the connector with the highest frequency rating. The rating should be displayed on the packaging.

Bail Coaxial Cablevision
Even if your Hi-Def TV is working fine, you might want to check to see that the coaxial cable is "bonded" to the house'southward grounding system. Bonding simply means connecting ii things to ensure electric continuity and conductivity. In a habitation, it's important that the electric system, communication 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 (force per unit area) and daze hazards that could be present during a lightning strike or other electric anomaly. A difference in voltage potential can create potent currents that can leap between two different systems through an undesirable path, and that path could be y'all!.
The simplest manner to bond your coaxial cablevision to the residue of the firm is to run the cables through a grounding block, and then run a wire from the cake to the grounding electrode (ground rod) or other qualifying grounding connection point. If you accept no idea where whatsoever part of the home's grounding system is, call an electrician. In addition to electrocution, improperly grounded cables could lead to damaged electronics and house fires.

Make a Drip Loop in Coaxial Cablevision
Exterior coaxial cablevision should never run sideways or downwards and directly into your business firm. Rainwater will attach to the cable and follow it right into your home. Loop the cablevision before it enters the building. The loop will non only help shed the water but besides provide actress cablevision for future work or repairs.
A feed-through bushing will allow you to drill a slightly larger hole so you tin can fish the cablevision through the wall without damaging information technology. Dab silicone caulk behind the bushing before pushing information technology into its last 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 good that you'll eventually miss the smash on the strap and whack the cable with your hammer by accident. A cable that's been crushed by a hammer is a cable that will corrupt a point. Straps with the screws already in identify are favored by pros.
9 / 22
Install a Low-Voltage Box for Coaxial Cablevision
Information technology'south much easier to fish a coaxial cable through a low-voltage box (sometimes called a "mud ring") than through a regular electrical box. But that's not the simply reason to utilize them. Depression-voltage boxes allow yous to push the extra length of wires into the wall crenel without over bending them. You'll harm the cable if you try to cram it into a small electrical box. Go out 8 to 10 in. of extra cablevision in the wall crenel just in case you want to make changes downwards the road.
10 / 22
Make Skilful Coaxial Cablevision Connections
You won't get a skillful connection if the dielectric portion of the coaxial able isn't pushed flush with the connector. If it'due south really difficult to do, you may have the wrong connector for the cable yous're working with. RG-59, RG-vi and RG-6 Quad all require different connectors.
11 / 22
Run Coaxial Cables Perpendicular to Electric Cables
Keep coaxial cables away from electrical cables. Electrical cables that run parallel with a coaxial cable can interfere with your bespeak. It's 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 cablevision quality. It blocks interference and keeps the signal clean. Skip the economy cable and become right for the "quad-shield" product. Quad-shield costs twice equally much as cable labeled "dual" or "double-shield." But after spending large bucks on your Idiot box or computer, skimping on coax just doesn't brand sense.
High-quality cable has 2 layers of metal foil and 2 layers of braided wire to block interference.
Economic system cable has just i layer of metallic foil and braided wire.
13 / 22
Cutting Coaxial Cable Advisedly
The signal carried by the coaxial cable center wire actually travels forth the outside of the wire, not through the within. And then a tiny nick in the wire can cause a big obstacle for the signal. That'southward why a special coaxial cable stripper (sold at home centers) is the merely tool y'all should utilize to gear up the ends of the cable for connectors. Never use 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 middle of coaxial cablevision is molded inside a foam jacket to go on it abroad from the shielding and to block interference. If yous kink the cable or curve it around a sharp corner, yous crush the foam. At that point, the damage is done and in that location's no mode to undo it. Never bend cable around a radius smaller than 3 in.
When coax cablevision kinks, the middle wire crushes its foam jacket and gets too close to the shielding. That leads to interference.
fifteen / 22
Don't Pull Too Hard
Coaxial cable is fragile, and kinking and crushing aren't the just ways to damage the foam jacket surrounding the center wire. Pulling coax cable too hard tightens the braided wire shielding and compresses the foam (the way 'Chinese handcuffs' tighten around your finger). That harms betoken quality. The maximum pulling force for RG-6 cable is 35 lbs. Make several curt pulls through walls and ceilings instead of a long tug-of-war pull.
sixteen / 22
Don't Run Coax Also Shut to Electrical Wiring
Electrical lines can cause nasty interference in coaxial cablevision. So keep coax cables as least 6 in. away from electrical cable, fifty-fifty if the cables are separated past wood or other building materials. To reduce any chance of trouble from telephone lines, install 'twisted pair' or shielded phone wiring. If the coax must cantankerous over an electrical line, create a 90-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 yous don't bulldoze 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 lot're running lots of coax, purchase a special cablevision stapler, which won't crush the cable. They're available at some abode 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 concord is ameliorate than a tight concur.
xviii / 22
Don't Let the Shields Evidence
The best cablevision-routing job can get fouled upward if you aren't careful when you attach the end connector. E'er fold back the foil and braided shield advisedly before yous adhere the connector. A single strand of braid protruding into the connector area can ruin the point. Double-cheque your piece of work before you crimp or compress the connector.
nineteen / 22
Don't Use Spiral-On Connectors
Solid connections at the ends of coax cable 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 cablevision can loosen up over time and fifty-fifty fall off. Instead, use crimp-ring mode coaxial cablevision connectors and a special crimping tool (sold at home centers), or ameliorate yet, compression-manner connectors. Pinch-type connectors grip cablevision firmly, without crushing the inner foam jacket as crimp-way connectors sometimes do.
20 / 22
Don't Just Finger-Tighten Coaxial Cablevision Connectors
Every bit with finish coaxial cable connectors, the threaded coaxial cable connectors on wall jacks, computers and TVs must provide a solid path for the point. Nearly people finger-tighten these connections, only that only isn't good enough. Instead, using a 7/16-in. wrench, plow the nut an extra quarter turn to snug up the connectedness.
21 / 22
Install Cable Outlet: Don't Apply Standard Electric Boxes
The sides and back on a standard electrical box force you lot to bend the cable sharply inside the box, which tin degrade the betoken. Low-voltage boxes allow you make a gentle bend considering they aren't really boxes at all, just frames that mount on drywall. These boxes are sold at home centers and can besides be used for phone, speaker and other depression-voltage wiring.
22 / 22
Don't Use a Cheap Splitter
Every fourth dimension yous dissever a Boob tube bespeak, it gets weaker. But you have to split the signal of your coaxial cable connectors if you desire to add a Tv set. Still, you can avoid poor motion picture quality. First, buy a splitter that can handle the bandwidth needed for high-definition television and high-speed Internet. If you get poor flick quality after installing a coax cablevision splitter for Television set and internet, phone 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 domicile centers, electronics stores and online (search for 'Tv set amplifier'). Only program to spend $50 or more to get ameliorate results. And keep your receipt so you can return the amplifier if it doesn't help. Judge a splitter by the numbers. If y'all accept cable service, purchase one labeled '5-1450 MHz.' For satellite TV, look for a high end of at least 2200 MHz.
