LMR195 and RG58 are both coaxial cables commonly used in RF applications, but there are some differences between them that may affect their suitability for specific applications. Here are some key differences between LMR195 and RG58:
- Construction: LMR195 has a solid centre conductor made of copper, surrounded by a dielectric insulator, a braided shield made of tinned copper, and an outer jacket made of PVC or polyethylene. RG58 has a stranded centre conductor made of copper or copper-clad steel, a dielectric insulator, a braided shield made of bare copper, and an outer jacket made of PVC or fluorinated ethylene propylene (FEP).
- Impedance: LMR195 has an impedance of 50 ohms, while RG58 has an impedance of 50 or 52 ohms, depending on the version.
- Attenuation: LMR195 has lower attenuation than RG58, which means that it can transmit signals over longer distances without significant signal loss. This makes it a better choice for high-frequency applications or long cable runs.
- Power handling: LMR195 can handle higher power levels than RG58, which makes it a better choice for high-power applications.
- Flexibility: RG58 is more flexible than LMR195, which makes it easier to bend and route in tight spaces.
- Cost: LMR195 is generally more expensive than RG58, due to its higher quality and better performance.
Overall, LMR195 is a better choice for applications that require low attenuation, high power handling, and long cable runs, while RG58 is a more cost-effective choice for applications that require flexibility and moderate performance.
