From the Designer
This custom hat by RF Cafe is a montage of Smith Charts with forbidden regions and associated L-C networks, with conversions between return loss, reflection coefficient, and VSWR.
Our adjustable, 100% brushed cotton Cap is unstructured and an ideal way to beat the heat. Wear it anytime you want to keep the sun off or cover up a bad hair day. It features a sturdy low profile brim, sweatband, and adjustable closure, as well as Premium Printing for images that last.
