Description
LMR-600-75-FR
LMR-600-75-FR cable is a Fire Retardant, Flexible, Ultra Low Loss, 75 ohm Coaxial cable, supplied in any length – manufactured by Times Microwave Systems and available from McGill Microwave – Authorised Distributor of all Times Microwave products.
LMR-600-75-FR Coaxial cable is a very popular product within the Times Microwave LMR coaxial cable range. 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.
The cable has excellent reliability, unsurpassed flexibility and ultra low attenuation. The LMR-600-75-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-600-75-FR is the fire retardant version of the LMR-600-75 cable.
How is the LMR-600-75-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 87% 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.
Outer Jacket
LMR-600-75-FR, Manufactured by Times Microwave Systems has a non-halogen (non-toxic), low smoke, fire retardant cable jacket. It is designed for in-building runs that can be routed anywhere except air handling plenums. LMR-600-75-FR is UL/NEC & CSA rated ‘CMR’ and ‘FT4’ respectively, meets FAA FAR25 requirements and is MSHA-P for mining applications.
Frequency Operating Band
LMR-600-75-FR is designed to operate excellent from DC – 6GHz. For any frequency band at VHF and above LMR is the obvious choice.
LMR-600-75-FR Flexible Low Loss Communications Coaxial Cable is ideal for:
- Satellite Applications
- VSAT applications
- Video applications such as CCTV, CATV, baseband or broadband
- In-Building Feeder Runs
- Any 75 ohm Wireless Application requiring an easily routed cable
Attenuation dB figures per 100m
Temperature range: -40⁰C – +85⁰C
