LMR-400-75 High-Performance 75 Ohm Flexible Low-Loss Coaxial Cable
LMR-400-75 is a 75 Ohm version of the world-renowned LMR-400 cable. It is specifically engineered for applications where signal integrity and low attenuation are critical but the system architecture requires a 75 Ohm impedance. It serves as a superior, high-performance replacement for RG-11 and other corrugated copper cables. Soyuztec Trading LLC is the exclusive distributor of Times Microwave Systems in the UAE and MENA region. We provide authentic, high-quality RF solutions for satellite, video, and wireless applications that demand the reliability of the industry-standard LMR series.
Features
-
Ultra-Low Loss: Designed to provide the lowest loss of any flexible 75 Ohm cable in its class.
-
Superior Shielding: Features a multi-ply bonded foil and tinned copper braid, achieving >90 dB RF shielding (50 dB better than typical single-shielded coax).
-
Weatherproof & Durable: The UV-resistant Polyethylene (PE) jacket is built for a 20-year service life in harsh outdoor environments.
-
High Flexibility: Enables tight bends (1-inch minimum bend radius) without the kinking or performance degradation common in “hard-line” cables.
-
Easy Installation: Compatible with EZ-400-FM-75-X (F-Type) and EZ-400-NMH-75-X (N-Type) solderless connectors for rapid field termination.
