Boas.<div>Tem de ver se ainda persiste RF no cabo coaxial.</div><div>Muito TVi é provocado pela radiação do cabo dentro de casa.</div><div>Pelas fotos que vi, o choke para ter mais eficiência nas low-band deveria ser bem maior.</div>
<div>Digamos que umas 30 espiras, nunca serão demais.</div><div>Pode começar por aqui, aumente-o ou adicione uma Ferrites de RFI ao cabo, e veja se melhora.</div><div><br></div><div>Tudo mais, configuração, SWR e montagem parecem boas.</div>
