Description

Filtro notch 88 108 MHz BNC

High Q notch filter with BNC connector. It allows the reduction of broadcasting frequencies from 88 to 108MHz. This version, designed to be connected only with receivers, scanners or sdr, allows a low-loss reception of frequencies also adjacent to the FM band such as the civil band at 78MHz and the 120MHz aerial band. Amphenol connectors, compared to the majority of connectors in circulation, allows a strong anchorage to the radio and to the aerial and and does not allow the aerial to turn with on itself. It can be used in the RX part on amateur and civil radio links either in vocal or in digital way APRS included. Ideal for listening to HF, 50 and 70MHz, Air band, NOAA, VHF, DAB, UHF, ADS-B and so on.

S21 Notch 88-108MHz

As it can be seen from the graph above, it is possible to adjust the deep exactly at 88, 98 and 108 MHz thanks to the manual calibration and unlike the other filters whose response is different from each other because there is no possibility of calibration.

Ottima qualità
Acquistato in versione BNC ha notevolmente aumentato la sensibilità del mio scanner. La cura nella lavorazione è elevata. Rapporto qualità/prezzo notevole. Consiglio caldamente l’acquisto
