Smith Chart RF Engineering Classic Dad Cap — RF Engineer Hat

This soft, low-profile dad cap speaks directly to RF engineers and ham radio enthusiasts who live in the world of impedance plots and transmission lines. Embroidered with a Smith Chart motif, the hat feels like a quiet nod to late-night lab sessions, soldering benches, and the exacting joy of matching networks. Wear it to conferences, lab days, or while tinkering on an antenna — it settles comfortably on your head and signals that you care about the details.

The precurved visor keeps sun and glare low while the understated embroidery keeps the look technical rather than flashy. The adjustable hideaway strap and antique brass hardware let you get a secure fit whether you’re climbing a rooftop or grabbing coffee between measurements. Made from breathable cotton and built with a classic 6-panel cut and sewn-in label, this cap blends everyday comfort with a specialist’s emblem — a small, confident way to show your craft.
