Most imported products are in the imperial system, and WX high-frequency heads and receivers are also in the imperial system. As for the domestic panels, branch distributors, and amplifiers, they are mixed in metric and English. The diameter of the F-head can be measured using a caliper, with a metric diameter of 9.7-9.9 millimeters; English diameter: 9.2-9.4 millimeters!
