L-195 was designed as a high performance drop-in replacement for RG-58, RG-122, RG-303, and RG-142. The double shielded outer conductor provides excellent RF shielding exceeding 90 dB, and its PE jacket provides for a service life in excess of 20 years.
L-195 cables are occasionally referred to as LMR-195, although the LMR prefix refers to the international trademark of Times Microwave. Each manufacturer instead uses their own prefix to reference a similar variation, such as CNT-195 (for Commscope), PTL-195 (for Powertec).
