Steel Jacket LMR 240 Coaxial Cable for Outdoor Environments

by | Apr 24, 2025

In outdoor operations, environmental exposure, physical wear, and RF performance requirements place heavy demands on every component of the communications system. Cabling is no exception.

Argo Wireless offers Steel Jacket LMR 240 cable assemblies engineered specifically for rugged applications where durability, signal integrity, and long service life are critical. With steel-armored construction and low-loss performance, these assemblies are well-suited for remote sites, manufacturing facilities, and outdoor infrastructure — delivering reliable connectivity in the most demanding conditions.

Engineered for Reliability in Harsh Environments: 

Steel Jacket LMR 240 offers the same low-loss electrical performance as standard LMR 240 but with enhanced mechanical protection. This makes it ideal for environments where cable runs are exposed to physical stress, abrasion, or risk of crushing like oil, gas, equipment yards, manufacturing and logistics.

Core Specifications:

Impedance: 50 Ohm
Frequency Range: DC – 6 GHz
Attenuation: Low-loss performance optimized for RFID, SCADA, remote sensing, and wireless telemetry
Shielding Effectiveness: >90 dB for EMI resistance
