Radio Frequency Systems (RFS) adds its ultra-flexible, foam dielectric coaxial cable to its CELLFLEX Lite range. Due to a corrugated copper inner conductor, the CELLFLEX Lite UCF cable has optimal bending properties, and it can be site-connected directly to base station antennas. Corrugated aluminum outer conductors are common to all versions of the cable. The ultra-flexible UCF cable represents the next step in the evolution of the range, following the earlier development of LCF versions. These comprise a 7/8 inches cable with a smooth copper-tube inner conductor and a 1-5/8 inches version with a corrugated copper-tube inner conductor. The Lite UCF version also complements the existing range of ultra-flexible all-copper cables, being the first with an aluminum outer conductor.
