If you're wiring a TV or modem, a 75-ohm RG6 coaxial cable is commonly used. Look for:

• Proper connectors: F-type ends (often labeled F81/RF) fit most TVs, cable boxes, and modems.
• Right length: Choose the shortest length that comfortably reaches to help reduce signal loss.
• Build quality: Solid-core center conductors and good shielding can support more consistent performance.
• Use case: Indoor runs typically use standard RG6; outdoor or in-wall runs may require specific jackets or ratings.

You can filter by length, connector type, and jacket style to match your setup. If you're unsure, check your equipment manual for connector and impedance requirements. Ordering online with pickup or delivery (where available) can make getting the right cable easier.

These coaxial types serve different purposes:

• RG6 (75 ohm): Common for TV, antenna, and cable internet connections. Typically uses F-type connectors.
• RG59 (75 ohm): Often used for shorter video runs, like some CCTV setups. Thinner than RG6, which can make routing easier but may introduce more loss over distance.
• RG58 (50 ohm): Used for radio-frequency gear and test equipment (e.g., oscilloscopes and spectrum analyzers). Frequently paired with BNC, SMA, or UHF-style connectors and labeled as low-loss for RF work.

Match the cable’s impedance and connector to your device. If your equipment specifies 50 ohm, stay with RG58-type solutions; if it specifies 75 ohm, RG6 or RG59 is more appropriate.

Start with a quality 2-way or multi-way splitter that supports the frequency range your services use. Then:

• Placement: Mount the splitter in a central location so runs to each room are as short as practical.
• Cables: Use well-shielded coaxial cables with the correct connectors to help limit signal loss.
• Unused ports: Cap any unused splitter ports with terminators to reduce noise.
• Signal management: Each split reduces signal strength. If you see issues, simplify the number of splits or consider professional evaluation for amplification needs.

It can help to keep your modem on the most direct leg. Equipment manuals usually note splitter specs that pair well with your devices.

For outdoor or direct-burial projects, use cables designed for the environment:

• Outdoor-rated jacket: UV-resistant jackets help withstand sunlight and weather.
• Direct-burial (flooded) cable: A water-blocking gel helps resist moisture when buried.
• Weatherized connections: Use compression connectors and weather boots; add drip loops to reduce water intrusion.
• Conduit: In high-traffic or rocky areas, conduit can add protection.

Follow local codes for burial depth and routing around utilities. If you’re unsure about your site conditions, consulting a qualified installer can help prevent signal issues or damage. You can filter for outdoor or underground-rated coaxial cable and the lengths you need before you buy.

Most test instruments like oscilloscopes and spectrum analyzers use 50-ohm paths. Consider:

• Cable type: Low-loss 50-ohm coax (often RG58) for general-purpose connections.
• Connector style: BNC is common; some gear uses SMA or other RF connectors. Adapters (e.g., SMA-to-UHF) can bridge different ports, but keeping adapters to a minimum may help signal integrity.
• Length and flexibility: Shorter jumpers can reduce loss; choose lengths that allow comfortable routing without sharp bends.
• Shielding: Well-shielded cables can help reduce noise in higher-frequency measurements.

Always match the instrument’s connector and impedance specs. Product pages list connector genders and lengths so you can pick the right fit.
