RF-LLF Flex

RF LLF 1/2" Hiflex

Variant:

Low loss highly flexible feeder cable designed for broadband transmission from sources like radio antennas, radars, GPS devices, mobile phone antennas to distribution systems inside ships, tunnels, buildings and underground areas wher RF signals normally cannot be received. The highly flexible design makes the product the best solution for installations which requires small bending radius. RF LLF 1/2" Hiflex is the best choice, used as jumper cable. The combination of extra flexibility and low loss makes RF LLF 1/2" Hiflex the natural choice for most applications in RF networks.
