The AF series cable is a UHF series economical radio frequency cable, which not only increases the cable attenuation with less floating but also greatly reduces 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;
