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.

S11 and S21 parameters of our notch 88 108 MHz Filter



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.
