Vlastná 140 mm anténa sa zdá byť najefektívnejšie a cenovo najdostupnejšie riešenie. Čim väčšia feritová tyč, tým lepšie.

77 parts, built around the BZW06-5V8. 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.
From the Servacek/numeri repository on GitHub, at the commit this page was made from: the board is __numeri-iv9-hodiny-atmega328.kicad_pcb and its schematic blokova_schema.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask Servacek before reusing the design.
