LCF series cables are UHF series economical radio frequency cables, which increase the cable attenuation with less floating and 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;
