РусскийWhen it comes to coaxial cables, two of the most common types are RG58 and LMR400. While they may seem similar, these cables have distinct characteristics that make them suitable for different applications. Understanding the differences between RG58 and LMR400 is crucial for anyone working with or selecting the right cable for their needs.
Characteristic Comparison
| Characteristic | RG58 | LMR400 |
|---|---|---|
| Impedance | 50 ohms | 50 ohms |
| Diameter | 0.195 inches | 0.405 inches |
| Attenuation | Higher | Lower |
| Flexibility | More flexible | Less flexible |
| Cost | Less expensive | More expensive |
Application Differences
| Application | RG58 | LMR400 |
|---|---|---|
| Usage | Low-power, short-distance (e.g. amateur radio, CCTV, jumper cables) | High-power, long-distance (e.g. cellular networks, satellite communications, military communications) |
By understanding the key differences between RG58 and LMR400 cables, readers can make informed decisions when selecting the appropriate cable for their specific needs, whether it’s for a home wireless network or a complex communication system.
