RFTypes of Coaxial Cable RG58 RG59 RG11 RG214:Key differences
Advertisement
Coaxial cables like RG‑58, RG‑59, RG‑11, and RG‑214 are standardized by the RG (Radio Guide) designation and cater to various impedance, frequency and signal stability needs. Let us understand differences between these coaxial cable types and explore their popular manufacturers.
Key differences
Here’s a table summarizing the characteristics of different coaxial cable types:
| Coaxial Cable Type | Characteristic Impedance (Ohm) | Outside Diameter (inch) | Frequency (MHz) | Attenuation (dB/ 100 ft) | Applications |
|---|---|---|---|---|---|
| RG-58/U | 53.5 | 0.195 | 100 | 5.3 | CB antennas |
| RG-59/U | 73 | 0.242 | 100 (400) | 3.4 (7.1) | TV antenna, Cable TV, HF antennas |
| RG-11/U | 75 | 0.405 | 100 (400) | 2.5 (5.5) | VHF antennas |
| RG-214/U | 50 | 0.405 | 100 400 900 | 2.0 4.7 7.8 | Satellite TV antennas, UHF and microwave |
| Twin lead | 300 | - | 100 | 0.55 | TV antennas |

Conclusion : Choosing between RG‑58, RG‑59, RG‑11 and RG‑214 depends on your application’s impedance, distance and frequency requirements. RG‑58 is ideal for low power RF and lab use; RG‑59 works well for short distance video; RG‑11 excels in long haul, low loss runs; and RG‑214 is best for rugged, high frequency systems. Matching the right RG type ensures optimal signal quality, minimal attenuation and reliable performance in your specific communication setup.
