Physical Characteristics
- Nominal OD (Outer Diameter): 4.95 mm (0.195 inches)
- Bending Radius: 100 mm (4 inches) static; 125 mm (5 inches) dynamic.
- Flexibility: High flexibility due to the braided shield and PVC jacket, allowing it to be routed through tight spaces in equipment racks.
Common Connector Types
- BNC (Bayonet Neill–Concelman): Most common for test instruments, GPS antennas, and RF modules.
- TNC (Threaded Neill–Concelman): Used in more secure connections (e.g., outdoor GPS timing antennas).
- N-Type: Larger connector, often used for higher power or main feeder connections (requires specific crimp tools for RG58).
- SMA (SubMiniature version A): Common in smaller wireless devices and radios.
Key Features
- 50-Ohm Impedance: Matches standard RF equipment, ensuring maximum power transfer and minimal signal reflection (VSWR).
- Cost-Effective: A budget-friendly solution for short-distance RF links and DC power injection.
- Reliable Shielding: The 90% braided shield provides good protection against electromagnetic interference (EMI) and radio frequency interference (RFI) in typical environments.
- Ease of Use: Its small diameter and flexibility make it easy to handle, route, and terminate in the field.
Applications
- GPS Antennas: Commonly used as jumper cables to connect GPS receivers to timing modules (e.g., in Nokia or Ericsson base stations).
- Test & Measurement: Used with spectrum analyzers, signal generators, and network analyzers.
- Ham Radio (Amateur Radio): Popular for short jumper cables between radios and antennas.
- Low-Power RF Systems: Suitable for Wi-Fi antennas, RFID readers, and walkie-talkies.
- DC Power Feeding: Often used to carry DC power to remote antennas (Power over Coax).
