Benefits of LMR Cable
Flexible:
 More flexible than corrugated copper cables; often eliminating the need for jumper cables.
Low Cost:
 The most cost effective choice for antenna feeders and jumper cables.
Low Loss:
 Loss comparable to corrugated copper cables.
Weatherproof:   

Black polyethylene UV protected jacket for long life. Bonded aluminum tape resists moisture ingress.

Special LMR Product

 

LMR Ultra Flex:    A stranded center conductor and a more flexible jacket make LMR-UltraFlex ideal for applications requiring repeated flexing, i.e. feedline from rotating beam antenna. Available sizes include 400 and 600. Attenuation is about 15% higher than for standard LMR cables. LRM-UltraFlex cable accepts standard LMR connectors.
   
LMR-FR,
Fire Retardant: 		   The LMR-FR cables have fire retardant, low smoke, non-halogenated jackets. The jackets are UV protected to allow longterm installation outdoors or indoors. They provide identical electrical performance to the standard LMR cables. UL CATVR listed for installation in risers, and have been approved for use by the London Underground.

Notes
(1) center Conductor in LMR900, LMR1200 and LMR1700 is Copper tube. center Conductor in LMR400, LMR-00 and LMR600 is Copper Clad Aluminum.
(2) Low loss, closed cell polyethylene foam, non-kinking.
(3) Aluminum Laminated Tape bonded to the Dielectric with a Tinned Copper Overbraid.
(4) Black, UV Protected Polyethylene. DB types are for direct burial.
(5) Less than 1 ohm impedance change at bend.
(6) LMR195 utilizes the same connectors as RG-58/U.
