Common coax types and practical uses
Match cable geometry to application - RG59 and RG6 are common for CCTV and TV, while low-loss coax such as RG11 or foam-dielectric types suit longer runs and RF use. For antenna feedlines, focus on impedance match (50 ohm vs 75 ohm) and loss per 100m at your operating frequency.
