GEARit Coaxial Cable for Direct Burial (75ft)
Product: GEARit Coaxial Cable for Direct Burial (75ft). Best for compact outdoor runs where a short, direct connection is needed. Made with OFC copper and triple shielding for signal integrity. Rubber boot adds weather resistance.
Best for: Small outdoor installations or ventures where budget-conscious, reliable direct burial is required. Selected for its suitable length and robust waterproof design.
Limitations: Limited length means extra connectors may be required for longer runs; consider the 100 ft or 200 ft versions for longer pathways.
GEARit Coaxial Cable for Direct Burial (100ft)
WIDE APPLICATIONS – Suitable for indoor or outdoor use, including Satellite, ISP Internet, video security, and cellular signal boosting.
FEATURES – OFC Oxygen Free Copper with triple shielding. Rubber boot and weather tolerance reduce moisture issues; precision 18 AWG conductors support dependable data transmission.
Best for: Mid-length outdoor runs where multiple protective features are valued, such as triple shielding and reliable moisture tolerance.
Limitations: Some installations may require additional outdoor-rated conduit for long pathways beyond 100 ft.
MOOKEERF Coaxial Cable 100FT
WIDE APPLICATIONS – Indoor/outdoor versatility; supports Satellite, ISP Internet, video security, and more.
FEATURES – 100% copper core, UV resistant PVC jacket, weatherproof rubber boot; high frequency range with corrosion-resistant nickel-plated connectors to minimize EMI/RFI.
Best for: Users needing robust all-weather performance with a focus on minimizing interference across a broad frequency range.
Limitations: Some users may prefer quad-shielded designs for very dense signal environments.
TRUECABLE RG6 Outdoor Quad Shield (500ft)
Extreme Performance – Quad shield with dual layer shielding, supports cable TV, HDTV, satellite, and more up to 3GHz.
DESIGN – 75 ohm, 18 AWG bare copper conductor; direct burial capability with UV-resistant jacket.
Best for: High-bandwidth installations where minimizing interference is critical, or when long outdoor runs require robust shielding.
Limitations: Longer lengths require careful grounding and conduit planning to maintain signal quality.
GEARit Coaxial Cable for Direct Burial (200ft)
WIDE APPLICATIONS – Indoor/outdoor use; suitable for Satellite, ISP Internet, video security, and other transmission needs.
FEATURES – OFC copper, triple shielding, rubber boot, moisture-tolerance; designed to endure ground exposure.
Best for: Long outdoor routes or installations needing extended reach while maintaining signal integrity.
Limitations: Longer runs may require proper splicing and protective routing to avoid signal loss at joints.
Buying Guide: Direct Burial Coaxial Cable Essentials
What does “direct burial” mean and why it matters
Direct burial cables are built to be installed underground without a protective conduit for short to moderate distances. They typically feature UV-resistant jackets, moisture barriers, and robust shielding to resist corrosion and EMI/RFI interference. For outdoor TV, internet, and satellite setups, choosing direct burial helps protect the signal and reduce maintenance needs.
Key materials and construction to look for
- OFC copper conductors for better conductivity and signal transfer.
- Triple or quad shielding (foil and braided) to minimize EMI/RFI.
- Weatherproof rubber boots and UV-resistant jackets for outdoor longevity.
- Direct burial compatibility and jacket thickness suitable for your soil and climate.
Length considerations and how to plan runs
Measure the required distance from the antenna or modem to each device. Round up to accommodate routing, connectors, and potential future expansion. For longer runs, consider longer lengths with high shielding to maintain signal quality.
Shielding and performance: quad vs. dual shielding
Quad shielding offers higher protection against interference, making it preferable in environments with multiple signal sources or long runs. Dual shielding may suffice for standard setups with minimal interference.
Installation tips: how to install safely and effectively
- Plan routing to minimize sharp bends and protect from physical damage.
- Avoid running cable parallel to power lines to reduce interference risks.
- Seal and backfill entry points to prevent moisture intrusion.
- Use proper connectors designed for outdoor use to preserve shielding integrity.
Frequently asked questions
- What is direct burial coaxial cable best for? Outdoor TV, broadband, and satellite installations that require protection from moisture and soil conditions.
- What is the difference between RG6 and RG6 Quad Shield? RG6 Quad Shield offers enhanced shielding to reduce interference, suitable for high-bandwidth needs and longer outdoor runs.
- Do I need conduit for direct burial cable? It depends on local codes, soil conditions, and exposure; some installations can be direct-burial, others may require conduit for added protection.
- How do I estimate the required length? Measure the distance from the source to the destination, add extra for routing and future expansion, and consider waste at bends and connectors.
- Can direct burial cable be used indoors? Yes, many direct burial cables are suitable for indoor use, but ensure the jacket and connectors meet indoor safety standards.
- Is shielding important for satellite installations? Yes, shielding reduces interference and ensures stable signal delivery to LNBs and receivers.
