Description

LMR-900

The LMR-900 has loss figures comparable to the extremely rigid corrugated coaxial cables such as CommScope AVA5 Series and Radio Frequency Systems LCF series.

The LMR-900 however, manages to achieve unsurpassed flexibility, making the cable extremely easy to install.Installing the connectors on this cable is very simple and fast. The ST-900C strip tool can help to speed up the process dramatically and ensure the correct strip distance is achieved with minimum effort.

How is the LMR-900 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 an Aluminium foil outer conductor, which is chemically bonded on to it. Due to the cable construction, The attenuation is significantly low. RF shielding of LMR-900 is > 90 db
