Physical Characteristics
- Nominal OD (Outer Diameter): 1.95 mm (0.077 inches) — Ultra-thin.
- Bending Radius: 10 mm (0.4 inches) static; 20 mm (0.8 inches) dynamic.
- Flexibility: High. Its tiny profile allows it to be routed through the smallest gaps inside cameras and electronic enclosures.
Common Connector Types
- SMA (75 Ohm Version): Used for high-frequency video and data links.
- MCX / MMCX: Common in compact video devices and modems.
- U.FL (IPEX): Surface-mount connectors found on mini-PCIe cards and HD video modules.
- BNC (Mini): Used in specialized test equipment.
Key Features
- 75-Ohm Impedance: Optimized for video bandwidth, ensuring compatibility with HD-SDI, HDMI internal wiring, and other video standards.
- Ultra-Low Loss Dielectric: The solid PTFE core ensures consistent impedance and low signal loss up to microwave frequencies (10 GHz+).
- High-Temperature FEP Jacket: Resists extreme heat, solvents, and chemicals, making it suitable for professional broadcast environments.
- High Shielding: The 95% braid provides excellent immunity to electromagnetic interference (EMI), crucial for clean video signals.
Applications
- HD Video Equipment: Used internally in professional video cameras, monitors, and recorders (e.g., connecting sensors to processing boards).
- Broadcast & SDI: Internal wiring for HD-SDI and 3G-SDI signal routing inside racks and gear.
- Medical Imaging: Used in endoscopes and ultrasound equipment where a small diameter and high image quality are required.
- GPS & Antennas: Used as a pigtail for 75-ohm GPS antennas or DAB/DVB-T tuners.
Important Note: RG179 vs. RG178
- RG178: 50 Ohms. Used for RF, Wi-Fi, and data communications.
- RG179: 75 Ohms. Used for Video, CATV, and high-frequency analog signals.
- Warning: These cables are physically identical in size and appearance, but electrically incompatible. Using a 50-ohm cable (RG178) in a 75-ohm video system will cause signal reflections and poor picture quality. Always verify the impedance before installation.

Product Description RG59 is a standard 75-ohm coaxial cable widely used in video and data transmission applications. Unlike the 50-ohm RG58 (used for RF), RG59 is designed specifically for low-frequency signals such as analog video, CCTV, and broadband internet. It features a smaller center conductor than RG6, which makes it more flexible and easier to route through walls and tight spaces, but it has higher signal attenuation at higher frequencies. It is the standard choice for tra...
