It’s great to reach a clean signal from FM stations, broadcasts or whatever on modern equipments as IC7300. This filter is fully designed and manufactured in our company in Calderara di Reno (BO). Elliptical filter with 7 cells, low pass 0-74MHz. Brass cells separator manufactured especially for this filter. Each cell shielding allows great performances as the possibility to transmit up to 74 MHz and to have at the same time a strong attenuation at 88 MHz of 40 dB(at 98 MHz of 50dB, see graph below). It also allows to cancel FM residuals through all the HF spectrum up to 74 MHz..

 Usage range :

Low pass filter with female/female SO239 connector. You can connect the filter directly between radio and antenna and use it in power with 100 watt. It’s ideal to break down FM residuals on HF (50 MHz and 70 MHz) frequencies for last generation radios like ICOM 7300 and similar. Low drop in reception up to 74 MHz.

Ideale per abbattere i residui di FM sulle frequeze HF, 50MHz e 70MHz sulle radio di ultima geneazione come ICOM 7300 o similari.

Ne eravamo sicuri io Jury e Dino Tersigni che il filtro passa basso 0-74 mhz avrebbe risolto al 90% i miei problemi dovuti a delle forti interferenze di QRN e noise allo stato puro. Infatti ricevevo dai 40 ai 10 mt solo segnali oltre il 9 ed adesso posso assicurarvi che per davvero sento segnali sotto i 5 db sia in fonia che in cw. Ottima fattura e resa. Veramente consigliato specie a chi ha problemi di noise legati a questa propagazione malsana. Grazie Ancora Marco in3ufw

Filtro passa basso
Ottimo prodotto, ha completamente risolto un problema di interferenza (spuria) sui 50MHz da parte di una stazione in banda FM
