LMR-600-FR-DB is a very popular coaxial cable in the industry due to its excellent reliability, surpassed flexibility and ultra low attenuation. Furthermore, the LMR-600-FR-DB 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-600-FR is UL/NEC & CSA rated ‘CMR’ and ‘FT4’ respectively, meets FAA FAR25 requirements and is MSHA-P for mining applications.
The LMR-600-FR-DB Series, Manufactured by Times Microwave Systems, has a very similar make up to the LMR-600 and uses the exact same LMR connector ranges, however there are 2 critical differences, with this cable being Fire Retardants and fully water blocked.
This cable has loss figures comparable to the extremely rigid corrugated coaxial cables however manages to achieve surpassed flexibility, making the cable much easier to install. Installing the connectors on the LMR-600-FR-DB cable versus corrugated copper cables in much quicker and simpler.
LMR-600-FR-DB Water Blocking Feature
In a normal scenario, if the outer jacket of a coaxial cable were to be cut for any reason – or damaged by wildlife, this would leave the cable with a potential leak path, directly leading to system performance degradation problems caused by increases of attenuation due to internal corrosion over time – especially if the cable was installed vertically as the moisture would travel down the cable with gravity.
The significant advantage of the LMR-600-FR-DB cable is that in the event of the cable outer jacket being damaged, the blocking agent flows to the area where the outer jacket has been damaged and effectively re-seals the cable – ensuring that the ingress threat is localised to the small area where moisture has entered the cable and prevents any further moisture ingress.
How It Works!
Between the tinned copper overall braid and the polyethylene jacket, there is a highly flexible water sealing compound. This acts as a fully sealed, protective secondary barrier should the jacket integrity be compromised anywhere along the cable.
The LMR-600-DB coaxial cable can therefore be used in any outdoor application, including underground and saturated environments.
When purchasing the LMR-DB series, you immediately benefit from the best warranty in the business – Times Microwave Systems 12-year warranty for any of the LMR-DB™ cable sizes.
How is the LMR-600-FR-DB 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 85% 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-600-DB is > 90 db.
All standard LMR coaxial cable comes with a UV resistant, PE Jacket. This helps to ensure the cable jacket can withstand harsh outside environments and UV rays from sunlight, this is designed to last for up to 20 years of outdoor service.
Frequency Operating Band
LMR-600-FR-DB is designed to operate excellent from DC – 6GHz. For any frequency band at VHF and above LMR is the obvious choice.
