Overview

LMR-200 is a 50 Ω coaxial cable type manufactured by Times Microwave, designed with a marginally larger center conductor than RG-58 and LMR-195 to provide reduced attenuation, while still maintaining a 4.95 mm overall diameter. The double shielded outer conductor provides exceptional RF shielding exceeding 90 dB, and PE jacket for a service life in excess of 20 years.

Several variations are available denoted by suffixes such as -FR for Fire Retardant, -DB for Direct Burial, and -UF for Ultra-Flex.

As the term LMR-200 is an international trademark of Times Microwave, each manufacturer will typically use a three letter prefix to reference their own similar variation, such as CNT-200 (for Commscope), KSR-200 (for KingSignal), and so forth.
