Description
LMR-300-LSZH
LMR-300-LSZH cable is a is a non-halogen (non-toxic), low smoke, fire retardant cable designed for in-building runs that can be routed anywhere except air handling plenums.
This cable has a CPR Reaction to fire rating of Eca. Test standard is EN50575:2017.
LMR-300-LSZH Flexible Low Loss Communications Coaxial cable, supplied in any length – manufactured by Times Microwave Systems and available from McGill Microwave – Authorised Distributor of all Times Microwave products.
The LMR range is recognised globally as the industry standard ultra-low loss, flexible, low cost, lightweight, DC – 6GHz coaxial cable solution for many RF applications. This is also backed up by the best warranty and technical support in the business.
Why choose LMR-300-LSZH?
LMR-300-LSZH is the most popular coaxial cable in the industry due to its excellent reliability, unsurpassed flexibility and ultra-low attenuation. The LMR-300-LSZH cable has loss figures comparable to the extremely rigid corrugated coaxial cables however manages to achieve similar flexibility to that of high loss RG Cables. LMR-300-LSZH is around 40% lower attenuation than RG Air-Dielectric type Cables.
How is the LMR-300-LSZH low loss figures achieved?
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 82% 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 as compared to single shielded coaxial cables: RF shielding of LMR-300 is > 90 dB as compared to 40 dB for RG213.
Frequency Operating Band
LMR-300-LSZH is designed to operate excellent from DC – 6GHz. For any frequency band at VHF and above LMR is the obvious choice.
