LMR-500-FR coaxial cable, Manufactured by Times Microwave Systems, is recognised globally as the industry standard ultra low loss, flexible, low cost, lightweight, DC – 6GHz coaxial cable solution for many RF applications.
LMR-500-FR is the fire retardant version of the LMR-500 coaxial cable. It 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. LMR-500-FR is UL/NEC & CSA rated ‘CMR’ and ‘FT4’ respectively, meets FAA FAR25 requirements and is MSHA-P for mining applications.
Why choose LMR-500-FR?
LMR-500-FR has excellent reliability, unsurpassed flexibility and ultra low attenuation. The LMR-500-FR 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-500-FR is around 40% lower attenuation than RG Air-Dielectric type Cables.
How is the LMR-500-FR 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 a 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-500 is > 90 db as compared to 40 dB for RG8.
LMR-500-FR has a UV Resistant FRPE Jacket. This helps to ensure the cable jacket can withstand harsh outside environments and UV rays from sunlight. The cable is also designed for indoor use. The cable is designed to last for up to 20 years of outdoor service.
Frequency Operating Band
LMR-500-FR is designed to operate excellent from DC – 6GHz. For any frequency band at VHF and above LMR is the obvious choice.
- Jumper Assemblies in Wireless Communications Systems
- Short Antenna Feeder runs
- 3G or 4G repeaters
- Radio antennas or receivers
- VSAT Applications
