FAQ

Questions engineers ask first

Not covered here? Send your drawing — an engineer replies within 2 business hours.

What is the difference between MIL-DTL-24643/30 (LS1S75MU) and MIL-DTL-24643/29 (LS1S50MU)?
Both share the same 10.80 mm outer diameter and double-braided LSZH XLPO construction, but LS1S75MU (/30) uses a smaller 18 AWG (7×26 AWG, Ø 1.21 mm) tinned copper center conductor inside the Ø 7.24 mm PE dielectric to achieve 75 Ω ± 3 Ω impedance for video, CCTV, and IF links, whereas LS1S50MU (/29) uses a 13 AWG (Ø 2.26 mm) conductor for 50 Ω RF transmitters.
Which legacy coaxial cable does LS1S75MU replace?
LS1S75MU is the low-smoke zero-halogen shipboard replacement for PVC-jacketed RG-216/U and double-braided RG-11/U 75 Ω coaxial cables.
When is the armored LS1S75MUS (M24643/30-01AU) required?
NAVSEA installation rules specify the braided aluminum wire armored -01AU variant where cables run in open overhead racks or weather-deck zones subject to mechanical abrasion and impact.
Can LS1S75MU be terminated with standard 75 Ω RG-216/RG-11 BNC and Type N connectors?
Yes. Its Ø 1.21 mm center conductor, Ø 7.24 mm PE dielectric, and double copper braid dimensions match standard MIL-PRF-39012 75 Ω RG-216/U connectors.
