New LMR-400 Flexible Low Loss Communications Coax has been released by Richardson  Electronics. The new LMR-400 Flexible Low Loss Communications Coax is ideal for: 
Drop-in replacement for RG-8/9913 Air-Dielectric type Cable
Jumper Assemblies in Wireless Communications Systems
Short Antenna Feeder runs
Any application (e.g. WLL, GPS, LMR) requiring an easily routed, low loss RF cable 

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 has a UL/NEC  & CSA rating of ‘CMR/MPR’ and  ‘FT4’ respectively.
 LMR- FR-PVC is a general-purpose indoor cable and has a UL/NEC & CSA rating of ‘CMR/MPR’  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 indoor/outdoor applications and is  somewhat more flexible than the standard polyethylene jacketed LMR.
 LMR- PVC-W is a white-jacketed version of LMR- PVC for marine and other indoor/outdoor  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 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-400  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-400 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-400 cable types are available as pre-terminated cable assemblies.
