Some coax cable is meant to be buried directly in the ground and other cables are not. If you look at the cable and find the words “direct bury” on the cable then you can go forward and bury it without a conduit. Cables that are not designed to be buried will quickly deteriorate with exposure to soil and moisture.
Full Answer
What cable is rated for direct burial?

What coax cable should be used for cable television?
- Center conductor: Usually made from copper-clad steel.
- Center Conductor bond: In which the use of clean stripping polymer prevents moisture migration.
- Dielectric: Made from polyethylene for a high-VP closed-cell foam.
- First outer conductor: An aluminum-polymer-aluminum tape is bonded with the dielectric core to create a shield.
What size coax cable be used for cable television?
If it is over 150 feet, RG-11 is normally used. RG-6 and RG-11 have copper clad steel center conductors.Then, the coaxial hardline (transmission and distribution lines) are .625″ and .875″ P3 semiflex cable is used. Hardline semiflex cables have a copper clad aluminum center conductor, and a solid aluminum shielding.
Does a coax TV cable have electricity?
Coaxial cable (or "coax") is the most common cable used for transmitting video signals. The name "coaxial" refers to the common axis of the two conductors. Construction. A coaxial cable has a solid copper or copper-clad-steel centre conductor surrounded by a non-conductive dielectric insulating material.

What kind of coax can be buried?
The RG11 Direct Burial coaxial cable is typically used for cable or satellite service.
Does heat affect coaxial cable?
Heat Damage If the center conductor and shielding touch, signal never makes it past that point. Coax should be kept away from heatsinks, stage lights, and other sources of heat. We have even heard of tightly bent cable shorting after being left out in hot sun.
Does coax cable degrade over time?
Do coaxial cables degrade over time? Yes. Unfortunately, a coaxial cable will degrade over time and need to be replaced to maintain the quality of the signal.
What is direct burial coax?
Direct burial RG6 coaxial cable is recommended for outdoor CCTV applications, especially where exposure to moisture is expected. This type of coax has a thicker UV resistant polyvinylchloride jacket to withstand sunlight and rain. It comes in both dual shielded and quad shielded versions.
Can RG6 be used outside?
Outdoor Rated RG6 F-Type Coax is used for applications that require the cable to be outdoors or in direct sunlight. All metal compression F-type connectors provide a secure watertight connection that won't deteriorate over time.
What is RG11 cable used for?
RG11 is a 14-gauge wire, a higher gauge than other video cables, giving it more room to transfer signal. RG11 cable provides 3Ghz frequency for CATV, HDTV, TV antenna, and video distribution.
Can I bury my own cable line?
At 18 inches, you can use THWN-2 conductors inside a continuous length of PVC conduit, which protects the wire all the way through the trench to the house. At 24 inches you can bury underground feeder cable, using PVC conduit to 18 inches below ground only where the wire comes up.

What happens when a data cable gets wet?
If a data cable gets wet, it will have higher attenuation which may impact performance in the field. Wet data cable changes the electrical characteristics of the cable as it introduces another conductive element, water, between each pair or singles.
Why is a cable used in industrial control systems?
Designed for use in high-end industrial control systems, the cable saves time, material and labor costs because it’s installable directly underground without a separate conduit. Sunlight resistant, oil resistant and flame retardant, this cable is built to withstand whatever situation it encounters underground.
Why do we need conduit?
Using conduit will protect your cables & signals underground —however, it adds another layer of complexity and cost to your project. If you need to run cable underground, but choose not to use direct-burial cable, then conduit is required. In these situations, two separate costs are incurred: cable material expenses and conduit material expenses.
Can you bury cable underground?
Direct burial cable. But not every cable that is outdoor-rated or says “burial-rated” can be directly buried underground with no protection. Let’s take a closer look at three types of cable often considered for outdoor applications.

If you’re running cable across long distances or alongside power lines, a PLTC-rated cable may be necessary. If the application involves oil for lubrication of moving parts, then a cable with an oil-resistant jacket may also be needed.
Can conduit be installed on top of rock?
To put it simply: If you don’t want to use conduit in your installation, then using a cable with a direct-burial rating is a must.
Can outdoor cable be buried?
Outdoor cable features outdoor ratings and maintains performance despite harsh conditions. It withstands moisture and high and low temperatures, and resists abrasion and tearing—but isn’t designed to be directly buried underground.
How far below ground do you need to dig to bury cable?
There's one restriction: It needs a conduit where the cable is exposed on the outside of the house and to 18 inches below the ground. Burying the cable 24 inches requires more digging, so this method only makes sense if you have easy-to-dig soil or are renting a trench digger.
How deep should I bury GFCI wire?
For a 12-in.-deep trench, you can direct-bury GFCI-protected underground feeder cable with a short length of PVC conduit at the house. At 18 inches, you can use THWN-2 conductors inside a continuous length of PVC conduit, which protects the wire all the way through the trench to the house.
How deep should I use UF-B cable?
At 12-in.-deep, use direct-bury UF-B (underground feeder) cable, provided it meets three criteria:#N#It has GFCI protection before it enters the ground;#N#Is limited to 120 volts (enough for your fountain );#N#Is protected by no more than a 20-amp fuse or breaker.
