La TEP - Trans Equatorial Propagation

La banda dei 50 MHz è spesso indicata col sinonimo “Magic band” per via delle combinazioni propagative che spesso influenzano questa gamma di frequenza che si trova tra le HF e le VHF. Per questo motivo essa è il crocevia delle caratteristiche propagative delle decametriche e delle onde delle frequenze molto alte (144 MHz per i radioamatori), anche se in via ordinaria è dominata da propagazione Troposferica che consente collegamenti dell’ordine dei 600-700 Km.
Tra i vari tipi di propagazione che interessano detta banda, in periodi ed orari specificatamente riscontrati, è presente anche la TEP, acronimo anglosassone di Trans Equatorial Propagation.
La TEP non è esclusiva dei 50 MHz, ma l’effetto più rilevante lo si ottiene proprio in questa frequenza. Si sfruttano casi di TEP sui 18, 21, 24 e 28 MHz, ma anche sui 70 e 144 MHz.
