Coaxial Cables

Match the connector and impedance to your device: most home TV and satellite systems use 75-ohm coax (F-type connectors), while some radio and professional systems use 50-ohm coax (BNC, N-type). Also consider cable construction (solid vs. stranded center conductor) and shielding level for signal type and distance

Longer coax runs increase signal attenuation; choose lower-loss cable types (e.g., RG-6 quad-shield or higher-quality coax) for runs over 50–100 feet. Keep runs as short as practical, avoid sharp bends, and use connectors rated for the cable to minimize additional loss

Coax prices vary by quality and length; budget options often start under $50 while premium or specialty options can be several hundred dollars; average products in this category are around $80. Allow extra for connectors, adapters, and professional installation if needed

Shielding (single, dual, quad) refers to the number of protective foil/braid layers around the conductor; higher shielding reduces external interference and is beneficial in high-noise environments or for long runs, improving signal stability

Common connectors include F-type (consumer cable/satellite), RCA (audio/video), BNC (professional video/radio), and N-type (higher-frequency radio). They are not directly interchangeable without an appropriate adapter or matching connector type on both ends

Use the correct connector and termination tool for the cable type to ensure solid contact and maintain shielding; keep connectors dry and use weatherproofing for outdoor runs, and inspect for kinks, corrosion, or damaged insulation periodically

Use coax rated for the signal frequency and bandwidth required: RG-6 or better (quad-shield, low-loss) is typical for 4K TV, satellite, and most cable internet; confirm the connector type and quality to support the provider's signal levels
