Cat5e Outdoor Waterproof Ethernet Cable 300ft - Direct Burial Shielded

In this review the Ultra Spec Cables 300ft Cat5e Outdoor Waterproof Ethernet Cable is evaluated for installers, homeowners, and anyone who needs reliable long-run networking outdoors. The bottom line: this cable is built to last outside and underground, with a tough PE jacket and foil shield that deliver stable connections over long distances, so the primary reason to buy is its combination of outdoor durability and dependable data performance for extended runs.

Key Features

• 300ft length: Provides a long single-run solution that avoids splicing for many yard, garden, or property layouts.
• Direct burial capable: The polyethylene jacket and construction let the cable be buried directly in the ground without conduit in appropriate installations.
• Shielded foil design: Foil shielding reduces electromagnetic interference for cleaner signal integrity in electrically noisy environments.
• 24 AWG pure copper: The 24 AWG conductor offers the balance of conductivity and flexibility expected from Cat5e wiring for Ethernet speeds at typical distances.
• TIA/EIA568-B.2 standard: Built to the industry cabling standard so it matches common networking termination and performance expectations.
• Weather-resistant jacket: The PE outer jacket is designed to withstand outdoor conditions like rain, sun, and temperature swings.

Who It's For

The cable suits network installers, CCTV/POE camera installers, and homeowners who need a long, single-run Cat5e cable that can live outdoors or underground without frequent maintenance. It is especially helpful where trenching and direct burial reduces installation cost and complexity.

It is less appropriate for applications demanding Cat6 bandwidth headroom or for indoor-only patching where a thinner, more flexible plenum or riser cable would be preferred. Buyers who require shielded STP connectors or factory-terminated runs should plan for compatible hardware or professional termination.

Pros & Cons

Pros

• Durable PE jacket and construction make it suitable for outdoor and underground use.
• Shielded foil reduces interference and helps maintain connection quality over long distances.
• Solid 24 AWG pure copper conductors provide reliable performance and build quality.
• Long 300ft length is excellent value for long property runs, eliminating frequent splices.

Cons

• Stiffer than indoor patch cable, which can make tight bends or neat indoor routing more difficult.
• Not a Cat6 cable, so it does not offer higher frequency headroom for future-proofing to gigabit-plus margins in some scenarios.

Specifications

Our Verdict

The Ultra Spec Cables 300ft Cat5e outdoor cable is a practical, cost-effective choice for outdoor networking and camera runs that need direct burial capability and solid shielding. Installers and homeowners who want a durable, well-built Cat5e run will find it good value, while those needing maximum flexibility or Cat6 performance should consider other options.
