Description
LMR-240-UF cable is an Ultra 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.
LMR-240-UF Background
LMR-240-UF 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.
Why choose LMR-240-UF?
LMR-240-UF has excellent reliability, unsurpassed flexibility and ultra low attenuation. The LMR-240-UF cable was designed to give more flexibility than the LMR-240 cable. It 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-240-UF is around 40% lower attenuation than competing RG Air-Dielectric type Cables.
How is the LMR-240-UF low loss figures achieved?
This is achieved due to the cable construction specifications. The centre conductor uses a high conductivity, Bare copper stranded centre conductor. The dielectric is nitrogen injected, foamed, closed cell, Polyethylene which helps achieve 80% 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
All UltraFlex LMR coaxial cables comes with a TPE outer jacket. This ensures maximum flexibility for repeated or periodic flexures.
Frequency Operating Band
LMR-240-UF is designed to operate excellent 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.
