Product Code : LMR-400
Product Description

We are known throughout the nation for engineering expertise in manufacturing Flexible Communications Cable. It is available in a wide range like automotive wiring harness,battery cables and ignition cables. The premium grade insulation material of Flexible Communications Cable allows this cables to withstand in high heat & environmental conditions. As per different market requirement, this Flexible Communications Cable is offered to our customers in different specifications.

ideal for...

  • Drop-in replacement for RG-8I9913 Air-Dielectric type Cable
  • Jumper Assemblies in Wireless Communications Systems
  • Short Antenna Feeder runs
  • Any application (e.g. WLL. GPS, LMR. Mobile Antennas, 802.11. WLAN) requiring an easily routed. low loss RF cable

Flexible: With a 1-inch minimum bend radius. LMR-400 cable can be easily routed into and through tight spaces with- out kinking. The LMR bonded-tape outer conductor provides superior flexibility and ease of bending compared to corrugated copper or smooth wall copper hard-line cables.

Low Loss: LMR-40ohasthe lowest loss of any RGBIRGZ13 ‘type’ table. This is achieved through the use of a high velocity gas-injected closed cell foam dielectric and bonded aluminum time outer conductor.

Weatherproof : The UV protected black polyethylene jacket makes the cable rugged and resistant to the full range of out- door environments. The 08 version of the cable includes a water blocking material within the braid to protect the cable from moisture ingress and eliminate any potential for commission in harsh environments or should the jacket become damaged. Various jacket materials are available to address other indoor and outdoor requirements.

RF Shielding : The bonded aluminum tape outer conductor is overlapped to provide 100% coverage. resulting in >90 dB RF shielding (>180 dB crosstalk) and excellent interference immunity (ingress and egress).

Phase Stability : The intimately bonded structure and foam dielectric of LMR cables provide excellent phase stability over temperature and with bending. The high velocity dielectric results in superior phase stability as compared with solid and air-spaced dielectric cables.

Connectors and Assemblies : Times Microwave provides Flex Tech‘" jumper cable assemblies fabricated with LMR-400- DB water tight cable and a variety of connector interface combinations (ref: Flex Tech pages). Custom assemblies with phase matching. Insertion loss matching. and other special electrical or marking requirements can also be provided. A full range of connectors. Including 'EZ' install (non-solder) types, is available for
