Propagazione

Approfondimento sulla propagazione delle onde radio: come si comportano nel vuoto e nell'atmosfera, quali fenomeni ne modificano il percorso e come leggere la larghezza di banda nelle designazioni di emissione.

Antenne

Panoramica delle antenne utilizzate in radioamatore: dipoli, verticali, direttive (Yagi, quad), parametri fondamentali come guadagno, impedenza, SWR e polarizzazione.
