RG59 Single Shield PVC (CMR/CMG) – 75-Ohm Coaxial Cable for CCTV & RF Applications
RG59 Single Shield PVC (CMR/CMG) is a 75-ohm coaxial cable designed for CCTV, analog video, and RF signal transmission. It features single shielding for basic EMI/RFI protection, a durable PVC jacket, and a CMR/CMG fire rating for safe indoor installations. This cable is widely used in security systems, broadcast setups, and general AV applications, providing reliable performance for short- to medium-distance transmissions in commercial and residential buildings.
Key Features
1. CMR/CMG Fire-Rated for Indoor Safety
- CMR (Riser) rating per UL 1666, suitable for vertical installations in riser spaces between floors.
- CMG (General-Purpose) rating per UL 1685, ideal for use in walls, ceilings, conduits, and non-riser spaces.
- Ensures fire code compliance for structured cabling in commercial and residential buildings.
2. 75-Ohm Impedance for Video & RF Transmission
- Designed for CCTV, analog video, CATV, and RF signal distribution.
- Supports low- to mid-frequency ranges, making it ideal for short- to medium-range transmissions.
- Compatible with BNC, RCA, and F-type connectors for versatile installations.
3. Single Shielding for Basic EMI/RFI Protection
- Features aluminum foil + braided shielding to minimize electromagnetic and radio frequency interference.
- Provides stable signal transmission for CCTV and analog video applications.
4. Durable PVC Jacket for Flexibility & Longevity
- Available in black or white for aesthetic and installation preferences.
- Rugged PVC outer jacket protects against abrasion and environmental wear.
- Flexible and lightweight for easy handling and installation.
5. Copper or Copper-Clad Steel (CCS) Conductor Options
- Solid bare copper (BC) version ensures better conductivity and low signal loss.
- Copper-clad steel (CCS) version provides cost efficiency with sufficient performance.
