Ottimo prodotto
Filtro fatto tarare appositamente per ricevere con la stessa antenna i satelliti a 137 e 145 Mhz. uso una turnstile autocostruita, il filtro va talmente bene che non uso più notch FM e premplificatore per i satelliti meteo, passa ggi puliti già a 2-3 gradi di elevazione, ricezione a Milano con tx fm a 2 km in linea d'aria. Ottimo lavoro.
