For many hams, portable operating starts simply: a wire in a tree, a folding chair, and the lure of making memorable contacts from a favorite spot. For Walt Hudson, K4OGO \u2014 better known to many as \u201cSalty Walt\u201d from YouTube\u2019s Coastal Waves & Wires \u2014 that spirit of the outdoors has always been the point.<\/p>\n
Now Walt is back with a second collection of antenna projects, Salty Walt\u2019s Next Level Portable Antenna Sketchbook<\/em>, expanding on the easygoing, field-tested style that made his first book a favorite among radio amateurs.<\/p>\n Where Salty Walt’s Portable Antenna Sketchbook<\/em> focused on beachside builds and creative wire antennas, the new volume ventures into even more concepts while keeping the designs approachable. Readers will still find practical, deployable antennas designed for parks, beaches, and backyard operating, but this time Walt explores ideas like phased arrays, beam-forming, and higher-gain directional arrays \u2014 all presented in his familiar notebook-sketch style.<\/p>\n \u201cDesigning, building, improving, and learning about antennas never ends \u2014 it evolves,\u201d says Walt. \u201cThis book is meant to take antenna building to the NEXT LEVEL.\u201d<\/p>\n The 17 projects range from relatively simple builds, such as a three-element vertical Yagi-Uda and half-square antenna, to more sophisticated designs including portable rhombics, bobtail curtains, and co-phased vertical arrays.<\/p>\n Throughout the book, Walt keeps the emphasis on learning-by-doing, with the same entertaining teaching style and relaxed voice that fans have come to expect. \u201cI referred to my first book as the Jimmy Buffett of antenna books,\u201d Walt says. \u201cWell, this is the second album, where the songs are only getting better.\u201d<\/p>\n Alongside the antenna projects, Walt shares radios from his personal collection, and operating tips to help amateurs get the most from their stations, whether running QRP or operating at 100 watts. The book also explores military-inspired antenna systems and streamlined wire antenna designs that can be deployed with minimal equipment. The result feels less like a technical manual and more like riding along on another operating adventure.<\/p>\n Salty Walt\u2019s Next Level Portable Antenna Sketchbook<\/em> is published by ARRL.
