LMR %400
Flexible Low Loss Communications Coax
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, WLAN, WISP, WiMax,
SCADA, Mobile Antennas) 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 ofwaterproofing
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' and `FT4'
respectively. In addition, the LMR -FR series is MSHA -P
rated for mining operations.
• LMR " - FR -PVC is a general - purpose indoor cable available as pre - terminated cable assembl
and has a UL/NEC & CSA rating of `CMR' and `FT4' the section on F1exTech for further details.
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: LNM 400 cables designed for outdoor
exposure incorporate the best materials for UV resistance
and have life expectancy in excess of 20 years.
• Connectors: Awide 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
ies. Refer to
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.
