The filter has been specially designed for the Crankk / Helium frequency band and impresses with its technical parameters. Interfering signals from other frequency bands (e.g. LTE) are efficiently filtered and removed. Therefore, a bandpass filter is particularly recommended in cities and near radio towers, as there is a lot of interference signals there.
Bandpass filters also have significantly better performance than SAW filters. As a result, they guarantee a much higher signal strength and signal range and are therefore ideal for combining with our Ampchampment amplifiers. (bandpass filters can also be used without an amplifier)
