LMR-400-DB Direct Burial coaxial 50 Ohm Low Loss coax Cable 10-40 metres

Description: McGill Microwave Systems introduces the LMR-400-DB Ultra Low Loss, water blocked coaxial cable seriesThe LMR-400-DB Series, Manufactured by Times Microwave Systems, has a very similar make up to the standard LMR-400 series and uses the exact same LMR® connector ranges, however there is one critical difference.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-400-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.Water Blocking feature and 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-DB coaxial cable product series can therefore be used in any outdoor application, including underground and saturated environments.LMR-400-DB ReliabilityWhen 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.Click here for our LMR400 ConnectorsClick here for your custom made LMR400 assemblyClick here for our Assembly ToolsHow is the LMR-400 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 84% 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-400 is > 90 db as compared to 40 dB for RG8.Outer JacketAll LMR standard 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 BandLMR-400-DB is designed to operate excellent from DC – 6GHz. For any frequency band at VHF and above LMR is the obvious choice.
