Crankk / Helium Bandpassfilter (Hohlraumfilter)
The filter is specifically designed for the Crankk/Helium frequency band and stands out with its superior technical parameters. It efficiently filters and removes interfering signals from other frequency bands (e.g., LTE). This makes a bandpass filter especially recommended in cities and near transmission towers, where high levels of signal interference are common.
Bandpass filters also offer significantly higher performance than SAW filters, ensuring greater signal strength and range. This makes them an excellent match for our Ampchampment amplifier. (Bandpass filters can also be used without an amplifier.)
