RG 217 CABLE

RG-217 is a robust, flexible coaxial cable used for transmitting high-frequency signals. It is designed to offer low attenuation and good shielding, making it suitable for a wide range of RF and microwave applications.

Specifications:

1. Construction:
   • Center Conductor: Typically made from solid copper or copper-clad steel with a diameter of approximately 2.1 mm (0.083 inches). Copper provides good conductivity, while copper-clad steel offers increased mechanical strength.
   • Dielectric Insulation: Usually made from polyethylene (PE) or similar materials. The dielectric material provides the necessary insulation and supports the central conductor.
   • Shielding: Often includes a combination of a foil shield (usually aluminum) and a braided shield (commonly tinned copper). This dual shielding provides effective protection against electromagnetic interference (EMI) and ensures minimal signal leakage.
   • Outer Jacket: Made from durable materials like PVC or rubber, which protects the internal components and provides flexibility.
2. Electrical Characteristics:
   • Impedance: 50 Ohms, which is standard for most RF and microwave applications.
   • Frequency Range: Capable of handling frequencies up to approximately 2 GHz, though some versions may support higher frequencies depending on the manufacturer and specific design.
   • Attenuation: Generally low, with typical attenuation values around 6 dB per 100 feet at 1 GHz. This low attenuation helps in maintaining signal strength over the length of the cable.
   • Return Loss: Typically ≥ 20 dB, indicating good impedance matching and minimal signal reflection.
3. Mechanical Characteristics:
   • Flexibility: Provides moderate flexibility, allowing it to be used in various installation environments while maintaining signal integrity.
   • Temperature Range: Generally operates within a temperature range of -40°C to +85°C, ensuring reliable performance across different environmental conditions.
4. Physical Dimensions:
   • Diameter: The cable diameter is approximately 7.3 mm (0.287 inches), making it thicker and more robust compared to many other coaxial cables.
   • Weight: Heavier and more robust than thinner coaxial cables, which contributes to its durability and high-power handling capabilities.

Applications:

• RF Systems: Ideal for connecting RF components and systems where high-frequency performance and minimal loss are required.
• Microwave Applications: Suitable for microwave systems due to its low attenuation and high power handling capability.
• Telecommunications: Used in telecommunications systems, including both broadcast and satellite communication.
• Test Equipment: Commonly used in test setups and laboratory environments for reliable signal transmission.
• Broadcasting: Employed in broadcast systems where durability and performance are essential.

Example Part Numbers:

• Manufacturer: Various manufacturers produce RG-217 cables, such as Belden, Amphenol, and others.
• Part Number Example: Belden 217 or similar. Check with the supplier or manufacturer for the specific part number and detailed specifications.

Visual Inspection and Installation:

• Connector Compatibility: Ensure that connectors are compatible with the RG-217 cable and are installed correctly to avoid signal degradation.
• Cable Handling: Handle the cable with care to prevent damage, especially given its robust construction and flexibility.
• Shielding Integrity: Inspect the shielding to ensure it is intact and properly connected to minimize signal interference.
