RG59 Siamese Plenum Coaxial Cable, BC 20 AWG, 95% BC Braid, 1000 ft. - White

RG59 Siamese Plenum (CMP) Coaxial Cable — 20 AWG Bare-Copper Video + 18/2 Power

Run power and picture through air-handling spaces in a single, code-compliant pull. This RG59 Siamese plenum cable combines a high-grade 20 AWG solid-copper video core with dual 18 AWG power conductors, delivering clean CCTV footage while meeting the strict flame-spread requirements of plenum ceilings and raised floors.

Why Install It

• All-in-One CCTV Backbone - Carries composite or HD-over-coax video and 12 V/24 V power together—no second cable to fish.
• 95 % Bare-Copper Braid - Heavy shield plus FEP dielectric blocks EMI/RFI for noise-free images, even near HVAC ductwork.
• True 75 Ω Impedance - Optimized for analog and HD-over-coax cameras, DVR/NVR inputs, and low-frequency RF gear.
• CMP / CL2P Plenum Jacket - UL-listed, ETL-verified, low-smoke compound limits flame spread in return-air spaces.
• Standards-Compliant & Eco-Friendly - RoHS compliant construction with solid copper signal conductor for minimal attenuation.

Typical Indoor Uses

• Ceiling-run CCTV camera drops in schools, hospitals, and office towers
• In-plenum connections for DVRs/NVRs, monitors, and security head-ends
• Low-frequency RF or digital-audio (S/PDIF) patching within commercial AV racks
• TV, VCR, and satellite-receiver hook-ups where plenum code applies

Because its electromagnetic field stays confined between the core and shield, the cable can run alongside metal ductwork or conduit without power loss—while the Siamese design cuts labor in half by delivering power and video together.
