Common Questions About Best Direct Bury Coax Cable

Why can’t I just use regular indoor coax cable outdoors?

Regular indoor coax cable is typically designed with a PVC jacket that is not UV resistant or waterproof. When buried, this jacket will quickly degrade due to moisture, soil acidity, and temperature changes, leading to water seeping into the core. This causes signal loss, corrosion, and eventual cable failure. Direct bury coax cable uses specialized jackets (like PE or LLDPE) and often includes internal flooding compounds or gel coats to prevent water damage.

What is the difference between bare copper and copper-clad steel (CCS) conductors?

Bare Copper (or pure copper) has superior conductivity and is crucial for installations where low voltage must be supplied through the coax cable, such as powering a satellite dish’s Low-Noise Block Downconverter (LNB). Copper-Clad Steel (CCS) is more rigid and less expensive. While CCS is perfectly adequate for standard signals (like cable internet or HDTV), it performs poorly when required to carry power over distance.

What burial depth is recommended for the best direct bury coax cable?

While specific depth requirements vary based on local building codes, generally, direct burial coax cable should be placed at a minimum depth of 6 to 8 inches to protect it from common yard activities like aerating and shallow digging. If crossing high-traffic areas or driveways, greater depth (12 to 18 inches) or the use of heavy-duty conduit is advised for mechanical protection.

Is conduit necessary if I use direct burial rated RG6 cable?

No, conduit is not strictly necessary as the cable jacket itself is designed to withstand direct contact with soil and moisture. However, using conduit is highly recommended because it offers mechanical protection against accidental cuts (e.g., from shovels or roots) and allows for easy replacement or upgrades of the cable in the future without having to dig up the entire run again.

What does “CL3 Rated” mean for direct burial cable?

The CL3 rating indicates that the cable is certified for in-wall installation, meaning it has a fire-resistant jacket suitable for use within residential structures. For outdoor and direct burial use, the key rating to look for is CMX, which specifically denotes outdoor/direct burial capability. Many of the best direct bury coax cable options carry both CL3 and CMX ratings, making them versatile for runs that go both in-wall and underground.

How does shielding (Dual, Triple, Quad) affect the signal?

Shielding refers to the layers of foil and braiding wrapped around the core conductor. More layers mean better protection against electromagnetic interference (EMI) and radio frequency interference (RFI).
* Dual Shielding is standard and effective for most residential areas.
* Triple Shielding provides added protection, ideal for longer runs or moderate interference.
* Quad Shielding (like that found on the Elecan cable) offers the highest level of noise suppression, critical for installations near power lines, motors, or cellular towers.
