Problema spurie nei ricevitori was created by

Ciao a tutti, vi pongo un quesito:

Mi trovo in trasferta per motivi di lavoro in città,
mi trovo a pochi metri da un palazzo su cui sono installate 4 direttive,
il problema è che ora i ricevitori mi vanno in saturazione facendo saltar fuori spurie a destra e a manca,
ho notato che se arrotolo l'antenna a mo di loop entro un certo diametro le spurie tendono a scomparire.

C'è qualche particolare "magheggio" da fare, tipo filtri, modifica all'antenna, oppure devo sorbirmi questo mix? ;D

Grazie,
Patrick

attacca all'antenna un bel notch sulla frequenza di trasmissione del tuo vicino!

Non male come idea!

Cercherò di reperire questo filtro e poi mi metto all'opera ;D
