Cables Direct Online 8-Way Waterproof Coaxial Splitter

The Cables Direct Online 8-way bi-directional coaxial splitter routes a single RG6/RG59 signal to eight outputs while protecting connections indoors or outdoors across 5–2300 MHz.

This heavy-duty splitter is built for multi-device setups that demand reliable distribution of TV, satellite, antenna, and broadband signals. It accepts standard RG6 and RG59 coax cables and preserves signal integrity with low loss design, EMI shielding, and a corrosion-resistant nickel-plated housing. Because the unit is bi-directional and waterproof, it supports signals both downstream and upstream and is suitable for exterior mounting when feeding multiple devices from a single feedline.

How does this splitter preserve picture and sound quality?

The splitter is engineered to minimize insertion loss across a wide frequency range, so connected devices receive consistent signal strength. Internal shielding reduces electromagnetic interference that can cause pixelation or audio dropouts. Proper impedance matching to 75 ohm coax cables also helps maintain signal fidelity throughout the distribution chain.

• Wide 5–2300 MHz frequency range for HDTV, satellite, and broadband signals
• EMI shielding to reduce external interference and noise
• Low insertion loss design to maintain signal level across outputs
• Bi-directional operation supports upstream signals and return-path devices

Can I use this outdoors, and how is it protected against weather?

The unit features a corrosion-resistant nickel-plated housing and weatherproof seals designed for exterior installations. All ports are protected to keep moisture, dust, and corrosion at bay; when installed with compatible weatherproof connectors, it withstands typical outdoor exposure. Still, mounting location and routine inspection will help extend service life in coastal or extreme climates.

• Nickel-plated, corrosion-resistant metal enclosure for outdoor use
• Weather seals on F-type connectors to block water ingress
• Screw-mountable body for secure exterior attachment
• Compatible with RG6 and RG59 when using proper outdoor-rated cable and connectors

Will this work with my existing equipment — cable box, satellite, antenna, and modem?

Yes. The splitter is compatible with standard 75-ohm RG6 and RG59 coaxial cables, making it suitable for cable TV, satellite receivers, digital antennas, and many broadband modems. Because it supports the common frequency bands used by these services, it integrates into most home and small-business AV or internet setups. For two-way services that require a return path (such as some internet or interactive TV features), the splitter’s bi-directional capability preserves that functionality.

• Works with RG6 and RG59 coax cables and standard F-type connectors
• Supports cable TV, satellite LNB feeds, terrestrial antennas, and many cable modems
• Bi-directional for return-path signals used by Internet and interactive services
• Available in multiple port counts if you need a different configuration

How do I choose placement and cable lengths for best performance?

Place the splitter as close as practical to the incoming feed to reduce cable run loss on the main line. Keep individual runs to devices as short as possible and use quality RG6 cabling and well-terminated F-connectors. If long runs are unavoidable, consider using an amplifier or distribution amplifier to compensate for cumulative loss across multiple outputs.

• Locate near the main feed to minimize signal loss on the primary line
• Use high-quality RG6 for long runs and professional crimped connectors
• For long or numerous runs, evaluate line amplifiers or powered splitters
• Inspect outdoor seals annually and re-tighten connectors after temperature cycles

Who is this for: Installers, hobbyists, and homeowners who need to distribute a single coaxial feed to up to eight devices while maintaining signal quality in indoor or outdoor environments. It’s well suited for shared antenna systems, multi-room HDTV setups, small commercial sites, and anyone wanting a durable, weather-resistant splitter that supports upstream signals and high-frequency services.
