Overview

Solid annealed copper center conductor (1.0 mm), physically foamed polyethylene dielectric (impedance held to ±2 ohm across reel), aluminum-foil + tinned-copper-wire braid double shielding, PVC outer jacket. Suitable for analog CCTV at runs up to 300m, HD-over-coax at runs up to 200m, and SDI video at runs up to 100m without active equalization.

Key Features

Stable 75-ohm impedance

Foamed-PE dielectric and tight geometric tolerance hold impedance within ±2 ohm — return loss stays acceptable across the cable length.

Double shielding

Foil + braid combination defeats both high-frequency and low-frequency interference — clean signal alongside fluorescent ballasts and HVAC motors.
