Most cable TV hookups use a coaxial cable with an F‑type threaded connector, typically RG6. It’s common for connecting the wall outlet to a cable box or modem.

• RG6 vs. RG59: RG6 is widely used for modern cable TV and internet. RG59 may appear in short, legacy runs.
• Shielding: Consider quad‑shield RG6 if you’re in a high‑interference area.
• In‑wall runs: Look for CL2‑rated cables and follow local codes or consult a qualified installer.
• Outdoor use: Weather‑resistant connectors can help reduce moisture issues.
• Fit and length: Choose the shortest length that’s practical; right‑angle ends can help behind tight cabinets.

Compatibility can vary by provider and equipment. Checking your device ports and service instructions can help you pick the best option.

Cable TV lines typically use F‑type threaded connectors on RG6 or RG59 coaxial cable. You’ll see these on wall plates, splitters, and the back of set‑top boxes.

• F‑type male connectors: The screw‑on ends that attach to devices and outlets.
• F81 couplers: Small female‑to‑female barrels used to join two coax cables.
• Splitters: F‑type in/out ports to divide a single line to multiple devices.
• Right‑angle adapters: Help with tight spaces behind TVs or cabinets.
• Compression/Weatherproof ends: Often used for a more secure, durable connection, especially outdoors.

Hand‑tightening is usually sufficient; overtightening can damage ports. If you’re unsure, reviewing your equipment’s connection labels can help.

You’ll see several cable types on TV setups. Common options include:

• HDMI (High/Ultra High Speed): One‑cable video and audio for streaming devices, Blu‑ray, and gaming; supports 4K/8K (device dependent) and features like eARC.
• Coaxial (RG6 with F‑type): For cable TV, cable modems, and over‑the‑air antennas.
• Optical audio (Toslink): Digital audio from TV to soundbar or receiver.
• RCA Composite (yellow video + red/white audio): Older DVD/VCR and retro consoles.
• 3.5mm TRRS to RCA: AV output on some camcorders or media players.
• S‑Video: Legacy video connection on some older gear.
• USB‑C to HDMI: Video from compatible laptops, tablets, or phones to a TV.

Device ports vary, and some newer TVs may need adapters for legacy gear.

It depends on what you’re connecting. Here’s a quick guide:

• Cable or antenna: Use RG6 coax from the wall plate or antenna to your TV or cable box.
• Streaming box or game console: Use an HDMI cable (High Speed or Ultra High Speed, depending on your device features).
• Soundbar: Use HDMI ARC/eARC if available, or an optical (Toslink) cable.
• Laptop/phone: Use HDMI or a USB‑C to HDMI cable if your device supports video out.
• Older players: Some use RCA composite or S‑Video; adapters may be required on newer TVs.

Check the ports on your TV and devices for the best match and choose lengths that fit your space without sharp bends.

For features like 4K at 120Hz or 8K, look for an Ultra High Speed HDMI cable (often labeled 48Gbps). This type is designed for higher bandwidth and can support advanced video modes when your TV and source device also support them.

• Compatibility matters: If your TV or device only supports earlier HDMI versions, a standard High Speed cable may be sufficient but won’t enable 4K/120 features.
• Length: Shorter cables can help reduce signal issues at high bandwidths.
• Audio: If you use eARC for high‑quality audio, ensure the cable supports it.

Results can vary by device and settings, so checking your TV and source specs is helpful.
