Overview
LMR-195 is a 50 Ω coaxial cable type manufactured by Times Microwave, and designed as a high performance drop-in replacement for RG-58 and RG-142. 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-195 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-195 (for Commscope), KSR-195 (for KingSignal), and so forth.
