This edition of the W3GMS 985 Workbench delivers a deep, practical dive into real-world amateur radio problems and solutions, with one of the most active and wide-ranging discussions of the month. Hosted by WA3VE, the group works through antenna theory, amplifier restoration, mobile antenna tradeoffs, and station-building decisions that every ham eventually faces.
Topics include G5RV feedline behavior and balun use, ladder line versus coax losses, Clipperton L amplifier restoration and power-supply capacitor upgrades, inrush current protection and step-start circuits, and hands-on advice for safely modernizing vintage HF amplifiers. The discussion also covers hex beam mechanical design, mounting considerations, and combining directional HF antennas with VHF/UHF verticals.
On the mobile side, the group breaks down short versus long VHF/UHF antennas, gain claims in dBi versus dBd, fender and bed mounting strategies for pickup trucks, garage-clearance realities, and why more metal still matters—despite marketing claims. New and experienced operators alike weigh in with practical field experience rather than theory alone.
As always, the Workbench blends technical depth with collaborative problem-solving, making it a valuable listen for anyone building, upgrading, repairing, or rethinking their amateur radio station.
