The Flexible RG58 cable is a widely used coaxial cable known for its versatility and flexibility, making it ideal for a variety of radio frequency (RF) signal transmission applications. The single-shielded RG58 cable typically comes with a black PVC jacket, which provides durability and protection against environmental factors. Here are the key features, specifications, and typical applications of this cable:

Key Features:

1. Single Shielded:
   • The RG58 cable is single-shielded, meaning it has one layer of shielding, typically made of braided copper or aluminum, which helps reduce signal interference and electromagnetic noise.
   • Although single shielding provides basic protection, it is suitable for moderate RF environments where extreme shielding isn’t necessary.
2. Flexible Design:
   • The flexible nature of RG58 makes it easy to bend and route in tight spaces, making it an excellent choice for applications requiring cable flexibility, such as in vehicle communication systems or indoor wiring setups.
3. Black PVC Jacket:
   • The PVC (Polyvinyl Chloride) jacket adds an extra layer of protection, making the cable resistant to environmental factors such as moisture, UV exposure, and mild abrasion. The black color enhances its durability for outdoor and indoor use while protecting against weathering.
   • The PVC jacket also provides insulation, helping to maintain the integrity of the signal being transmitted through the cable.
4. 50 Ohm Impedance:
   • RG58 cables have an impedance of 50 ohms, which is standard for many RF and data transmission applications, particularly in communications, radio antennas, and networking.
5. Stranded Copper Core:
   • The core conductor of the RG58 cable is often made from stranded copper or copper-clad steel, ensuring good conductivity while maintaining flexibility.

Specifications:

• Impedance: 50 Ohms
• Capacitance: ~25 pF/ft (83 pF/m)
• Maximum Frequency: Typically up to 1 GHz, though it may be used in higher frequencies depending on the application and length.
• Cable Diameter: ~0.195 inches (4.95 mm)
• Jacket Material: Black PVC (resistant to UV, moisture, and abrasion)
• Shielding: Single braided shield (typically copper or aluminum)
• Conductor Material: Stranded copper or copper-clad steel

Typical Applications:

1. RF Communications:
   • RG58 is commonly used for radio frequency (RF) communications, particularly in two-way radio systems, Wi-Fi networks, and CB radios.
2. Antenna Connections:
   • It is often employed in antenna feed lines due to its impedance matching capabilities and flexibility, making it ideal for short-distance antenna setups like those found in vehicles or marine communication systems.
3. Laboratory Testing:
   • Due to its flexibility and ease of handling, RG58 is used in test and measurement setups in laboratories for signal testing and monitoring equipment.
4. Networking and Data Transmission:
   • RG58 cables are still used in some older Ethernet networks (10Base2), although more modern networking technologies have replaced this in most scenarios.
5. CCTV and Surveillance Systems:
   • The cable is also used in CCTV systems for signal transmission between cameras and monitoring equipment.
6. Military and Aerospace:
   • In military or aerospace applications, RG58 cables are favored for their lightweight and flexible design, suitable for secure communications and signal transmission in limited-space environments.

Considerations:

• Signal Loss: The RG58 cable experiences some signal loss, especially at higher frequencies and over long distances. It is typically better suited for short to medium runs.
• Interference: While the single shield offers basic protection against RF interference, it may not be sufficient in environments with heavy electromagnetic interference (EMI). For such cases, double-shielded or more robust cables might be necessary.

The Flexible RG58 Single Shielded Cable with a black PVC jacket is a versatile coaxial cable suitable for a wide range of RF applications, offering flexibility, ease of installation, and moderate shielding. It is widely used in communications, networking, and testing environments where short to medium-range signal transmission is required. Its durable black PVC jacket makes it suitable for both indoor and outdoor use.
