ZhongTong Premium 75-Ohm Solid Copper RG59 Coaxial Cable (3G-SDI HD Video Grade, White/Black Optional)

High-Purity Solid Copper Center Conductor: Utilizes a solid bare copper core instead of cheap copper-clad steel (CCS). Solid copper maximizes low-frequency baseband transmission, preserves DC power loop stability for coaxial telemetry (PTZ control), and keeps signal attenuation minimal over long cable runs.

True 75-Ohm Broadcast Match: Engineered to maintain a strict, uniform 75-Ohm impedance rating throughout the entire spool, preventing signal reflections and jitter in critical 3G-SDI high-definition ($1080\text{p}$) digital video paths.

Multi-Layer Interference Shielding: Bound with a high-coverage metallic braid shield and premium aluminum foil wrap. This layered matrix delivers comprehensive defense against electromagnetic interference (EMI) and radio frequency interference (RFI), keeping video feeds crisp near industrial power grids.

Dual Sheath & Color Customization:

• PVC Sheath (Indoor/General): Flexible and flame-retardant, perfect for routing through interior wall spaces and drop-ceilings.

• PE Sheath (Outdoor/Heavy-Duty): Highly resistant to water ingress, extreme temperatures, and mechanical pulling forces.

• Aesthetics: Available in White for clean, low-profile blending along office baseboards or Black for concealed commercial utility trays.
