LMR -240
Flexible Low Loss Communications Coax
®
Ideal for…
• Jumper Assemblies in Wireless Communications Systems
• Short Antenna Feeder runs (e.g. WLL, GPS, LMR,
Mobile Antennas)
• 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 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 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 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.

• Low Loss is another hallmark feature of LMR-240.
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-240 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-240 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-240 cable types are
available as pre-terminated cable assemblies. Refer to
the section on FlexTech for further details.

• Flexibility and bendability are hallmarks of the LMR-
240 cable design. The flexible outer conductor enables
the tightest bend radius available for any cable of similar
size and performance.
