HP-41 User’s Library Solutions ANTENNAS Vintage Manual 00041-90093
The HP‑41 User’s Library Solutions: ANTENNAS (Manual 00041‑90093) is a vintage Hewlett‑Packard application booklet created for engineers, radio operators, and technical users who relied on the HP‑41C programmable calculator for field calculations. This manual focuses specifically on antenna theory and practical computation, providing ready‑to‑run HP‑41C programs for tasks such as radiation‑pattern evaluation, gain and beamwidth estimation, impedance and matching calculations, and wavelength‑related geometry. Like other volumes in the User’s Library Solutions series, it blends concise technical explanations with keystroke‑level program listings, allowing users to turn the HP‑41C into a portable RF‑engineering tool long before laptops were common. Collectors value this 00041‑90093 edition not only for its specialized content but also as a snapshot of early 1980s handheld‑computing culture, when HP’s programmable calculators were essential instruments in professional engineering workflows.Book is in Good+ condition with little exterior wear and bumped corners. Otherwise, covers and pages are square, clean, bright, and unmarked. Interior looks very good. Binding is sound. Please see pictures as they are considered part of the condition description. I take numerous photos of the actual item and describe it as accurately as I can so you don't have to risk your buying decision on stock photos, generic condition descriptions, insultingly ridiculous AI sales pitches, or "See pictures for condition" making you ferret out any flaws.A portion of this sale goes to a US Food Bank in honor of my father-in-law who was a director of a food bank.
