Why choose LMR-195?
LMR-195 has excellent reliability, unsurpassed flexibility and ultra low attenuation. The LMR-195 cable is a drop-in performance upgrade for RG-58 and RG-142. This means the LMR-195 cable has similar mechanical specifications, however the electrical performance is much higher.
How is the LMR-195 performance higher than competing RG cables?
This is achieved due to the cable construction specifications. The centre conductor uses a high conductivity, bare copper clad covered aluminium centre conductor material. The dielectric is nitrogen injected, foamed, closed cell, polyethylene which helps achieve 80% velocity of propagation. The dielectric has an aluminium foil outer conductor, which is chemically bonded on to it. Due to the cable construction, the attenuation is significantly lower and VP is higher as compared to single shielded RG coaxial cables.
| Velocity of Propagation Comparison | |
| Cable | VoP |
| LMR-195 | 80% |
| RG-58 | 66% |
| RG-142 | 69% |
Outer Jacket
All standard LMR coaxial cable comes with a UV resistant, PE jacket. This helps to ensure the cable jacket can withstand harsh outside environments and UV rays from sunlight, and is designed to last for up to 20 years of outdoor service.
Frequency Operating Band
LMR-195 is designed to operate excellently from DC – 6GHz. For any frequency band at VHF and above, LMR is the obvious choice.
Should you find your RF system operates at above 1GHz, LMR is once again your best option, as RG cable typically isn't compatible with any frequency in excess of 1GHz.
