Questions
How big is the Wire Spool Antenna Ultra V1.5 PCB?
It measures 75.4 × 74.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wire Spool Antenna Ultra V1.5 use?
13 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Wire Spool Antenna Ultra V1.5 KiCad files?
From the modulo8/KO4HUI-Spooltenna repository on GitHub, at the commit this page was made from: the board is ULTRA v1.5/Wire Spool Antenna Ultra V1.5.kicad_pcb and its schematic ULTRA v1.5/Wire Spool Antenna Ultra Blank V1.4.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wire Spool Antenna Ultra V1.5 design in my own project?
Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
