Conductor: Annealed copper, typically solid or stranded. Commonly in the range of AWG 20 to AWG 30.  
Insulation Layer: Solid or foamed polyethylene, which is the key layer for constructing its characteristic impedance.  
Shielding Layer: Aluminum foil shield + braided copper shield, typically dual-shielded to provide excellent interference resistance.  
Sheath: Polyvinyl chloride (PVC) or flame-retardant polyolefin.  
Characteristic Impedance:75 ohms ± a certain percentage (e.g., ±3Ω). This is its most critical electrical parameter, specifically designed for video and RF signal matching.  
Rated Voltage:300 Volts (for signal transmission purposes, voltage is not the primary consideration).  
Long-term Operating Temperature:80°C (common). Some models can reach 105°C.  
Minimum Bending Radius:6 × D (D: cable outer diameter; careful bending is required to prevent impedance discontinuity).  
Attenuation: The signal loss value (dB/100ft) at specific frequencies (e.g., 100MHz, 400MHz) is a key metric for evaluating its performance.  
Shielding Effectiveness:** Typically requires high high-frequency shielding attenuation (e.g., > 90 dB @ 1 GHz).
