TIMES MICROWAVE SYSTEMS LMR -195 Flexible Low Loss Communications Coax ® Ideal for… • Jumper Assemblies in Wireless Communications Systems • Short Antenna Feeder runs • Any application (e.g. WLL, GPS, LMR, WLAN, WISP, WiMax, SCADA, Mobile Antennas) requiring an easily routed, low loss RF cable • Drop-in replacement for RG-58 and RG-142 • LMR standard is a UV Resistant Polyethylene jacketed cable designed for 20-year service outdoor use. The bending and handling characteristics 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-toxic), low smoke, fire retardant cable designed for in-building runs that can be routed anywhere except 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 jacketed LMR. • LMR - PVC-W is a white-jacketed version of LMRP V C f o r m a r i n e a n d o t h e r a p p l i c a t i o n s where color compatibility is desired. • LMR - MA is a flexible cable designed specifically for mobile antenna applications. It has a PVC jacket and un-bonded aluminum tape to facilitate end stripping with automated equipment. • Flexibility and bendability are hallmarks of the LMR195 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-195. Size for size LMR has the lowest loss of any flexible cable and comparable loss to semirigid hard-line cables. • RF Shielding is 50 dB greater than typical single shielded 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-195 cables designed for outdoor exposure incorporate the best materials for UV resistance and have life expectancy in excess of 20 years. • Connectors: A wide variety of connectors are available for LMR-195 cable, including all common interface types, reverse polarity, and a choice of solder or non-solder center pins. Most LMR connectors employ crimp outer attachment using standard hex crimp sizes. • Cable Assemblies: All LMR-195 cable types are available as pre-terminated cable assemblies. Refer to the section on FlexTech for further details.
