Product description

LCF series cables are UHF series economical radio frequency cables, which not only increase the cable attenuation with less floating, but also greatly reduce the cable cost. It is woven with low-density PTFE medium, aluminum foil longitudinally wrapped and silver-plated wire. This series of products are widely used in electronic countermeasures, military electronic equipment and other applications;
