 Field of Use :

Notch high Q filter with BNC connectors. It allows the reduction of broadcasting frequencies from 88 to 108MHz. This version designed to be matched only to receivers, scanners or SDR allows low-loss reception of frequencies adjacent to the FM band such as the civil band at 78mhz and the 120MHz aerial. The Amphenol connectors, compared to most of the connectors in circulation, allow a strong anchorage between radio and antenna ensuring that the antenna does not turn, with its weight, on itself.

It can also be used in the RX part on radio amateur and civilian bridges both in voice and in digital APRS including.

Ideal for listening HF, 50 and 70mhz, Airband, NOAA, VHF, DAB, UHF, ADS-B etc...

 Uniqueness :

All notch filters of our production are calibrated one by one in order to have the maximum attenuation exactly at 88,98 and 108 MHz with a maximum error of 3%.

S21 Notch 88-108MHz

As you can see from the chart above thanks to manual calibration you can adjust the deep exactly to 88, 98 and 108 MHz and not as happens on the filters of all the competition where the filter responses is different from each other because there is no possibility of calibration.

Domande e risposte:

Che differenza c'è rispetto a filtri notch più economici che ho visto in rete ?

Tutti i nostri filtri notch montano induttanze e condensatori ceramici ad alto Q e con tolleranze inferiori all'1%. Le induttanze regolabili al loro interno permetto la taratura a mano dei filtri permettendo una esatta e precisa attenuazione a 88,98 e 108 MHz. Questo permette di produrre filtri perfettamente tarati e con basse attenuazioni in banda aerea e bande civili.

Ottimo prodotto a un costo contenuto
Per qualsiasi ricevitore SDR, per scanner palmari, ma anche per RTX cinesi da 4 soldi, un filtro come questo viene sempre utile, soprattutto se vogliamo collegarli ad una antenna esterna e non al gommino di serie. Filtrare via l' FM (ma temo che presto dovremo fare i conti anche con il DAB) è l'unico modo per non assordare totalmente gli apparati molto economici oppure quelli che per definizione devono avere una larghezza di banda enorme in ingresso. Il filtro che possiedo io è uno dei primissimi modelli, quelli nuovi dovrebbero essere ancora migliori.
