RG58 Cables exist in numerous versions based on the conductor and shielding structure:1. RG58/U Cable:
- Standard version.
- Solid copper conductor.
- Suitable for most RF applications.
- Cost-effective and simple to install
2. RG58 A/U Cable:
- Stranded copper conductors
- More flexible and durable.
- Used for mobile and vehicle installations.
3. RG58 C/U Cable:
- Military-grade insulated cable.
- Improved durability.
- Low signal loss.
- Suitable for outdoor or severe situations.
Key Features of the RG58 Cable :
- 50 Ω impedance for RF and instrumentation.
