LMR-400
Flexible Low Loss Communications Coax
Ideal for....
. LMR Standard is a UV Resistant Polyethylene jacketed cable designed for 20-year service outdoor use. The bending and handling characteristic are significantly better than air-dielectric and corrugated hard-line cables.
. LMR-DB is identical to standard LMR plus has the advantage of being watertight. The addition of waterproofing compound in and around the foil/braid insures continuous reliable service should the jacket be inadvertently damaged during installation or in the future.
. LMR-FR is a non-halogen (non-texic), low smoke, fire retardant cable designed for in-building runs that can be routed anywhere wxcept air handling plenums. LMR-FR is UL/NEC & CSA rated 'CMR' and 'FT4' respectively, meets FAA FAR25 requirements and is MSHA-P for mining applications.
. LMR-FR-PVC is a general-purpose indoor cable and has a UL/NEC & CSA rating of 'CMR' and 'FT4' respectively. it is less expensive than LMR-FR, however it emits toxic fumes (HCL) and greater smoke density when burned.
. LMR-PVC is designed for low loss general-purpose applications and is somewhat more flexible than the standard polyethylene jacket LMR.
.LMR-PVC-W is a white-jacket version of LMR-PVC for marine and other applications where color compatibility is desired.
. Flexibility and bendability are hallmarks of the LMR-400 cable design. The Flexible outer conductor enables the tightest bend radius available for any cable of similar size and performance.
. Low Loss is another hallmark feature of LMR-400. Size for size LMR has the lowest loss of any flexible cable and comparable loss to semirigid hard-line cable.
. RF Shielding is 50 dB greater than typical single scielded coax (40 dB). the multi-ply bonded foil outer conductor is rated conservatively at >90 dB (i.e.>180 dB between two adjacent cables)
. Weatherability : LMR-400 cable designed for outdoor exposure incorporate the best materials for UV resistance and have life expectancy in excess of 20 years.
