Questions
How big is the TransmissionLineTest PCB?
It measures 75 × 34 mm and has 4 copper layers, 1.6 mm thick.
What parts does the TransmissionLineTest use?
14 parts, built around the ADT1-1WT+. 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 TransmissionLineTest KiCad files?
From the TopQuark12/transmissionLineTest repository on GitHub, at the commit this page was made from: the board is transmissionLineTest.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the TransmissionLineTest design in my own project?
Its repository states no licence, so its author keeps all rights: ask TopQuark12 before reusing the design.
