NAI Introduces New STEADY LINK® Series-C LMR* 240 and LMR 400 Diameter Coax Cable Assemblies

Troy, MI – NAI, a leading designer and manufacturer of custom interconnect solutions which deliver power and signals to monitor data, connect people and keep equipment operating, continues its introduction of new standard interconnect products under the STEADY LINK® brand with the launch of a new line of Series-C LMR* 240 and 400 coaxial cable assemblies.  Series-C coax jumpers are designed to address the dramatic increase in the use of mobile devices by providing interconnect solutions to service 4G LTE and 5G wireless and industrial network applications.

NAI’s STEADY LINK® Series-C LMR* Coax Cable Assemblies have been designed to provide durable and reliable short run feeder connections to anten­nae in WISP, SCADA, GPS, and mobile transmission of communication.  These indoor/outdoor assemblies are well suited for connections in high frequency, low loss applications where routing space is minimal and multiple flexing is expected.

STEADY LINK® Series-C coaxial cable assemblies represent a cutting-edge solution for harsh outdoor environments.  Engineered to withstand extreme temperatures, their ruggedized design will also tolerate other demanding conditions of continued outdoor exposure.

These new Series-C LMR 50-ohm coax jumper families offer a variety of straight, right angle, male and female connectors for pretermination at both ends.  The LMR 400 cable assemblies feature a 0.405” cable diameter, while the LMR 240 has a 0.240” O.D.  Both assemblies can be provided in custom lengths.

RF 50-Ohm Coaxial Cable:

The LMR 240 cable assembly features a solid bare copper center conductor, while the LMR 400 cable features a solid bare copper-covered/clad aluminum (BBCAL) conductor.  Both LMR assemblies include a double shield with an aluminum foil tape and a tinned copper outer braid shield, along with Foam Polyethylene for the dielectric and an outer PE jacket.  See the Data Sheets for more details.
