(800) tms-coax ? www.timesmicrowave.com 10 times microwave systems lmr ? -195 flexible low loss communications coax LMR-195 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 ? low loss is another hallmark feature of LMR-195. size for size lmr has the lowest loss of any fexible 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. ? lmr ? standard is a uv resistant polyethylene jacketed cable designed for 20-year service outdoor use. the bending and handling characteristics are signifcantly 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 waterproofng 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, fre retardant cable designed for in-building runs that can be routed anywhere except air handling plenums. lmr-fr is ul/nec & csa ratedcmr 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 lmr- p 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 fexible cable designed specifcally 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 lmr- 195 cable design. the fexible outer conductor enables the tightest bend radius available for any cable of similar size and performance. part description stock part number application jacket color code LMR-195 outdoor pe black 54110 LMR-195-db outdoor/watertight pe black 54113 LMR-195-fr indoor/outdoor riser cmr frpe black 54111 LMR-195-fr-w indoor/outdoor riser cmr frpe white 54158 LMR-195-fr-pvc indoor/outdoor riser cmr frpvc black 54105 LMR-195-ma mobile antennas pvc black 54210 LMR-195-pvc general purpose pvc black 54215 LMR-195-pvc-w general purpose pvc white 54199 construction specifcations description material in.
