I have bought this receiver because the particular combination of components used not only television and radio reception allows the unit but also as effective radio scanner (keyword: SDR - Software Defined Radio) is applicable for all frequencies 24-1850 MHz. In particular, I felt around 1090 MHz - because on the frequency send aircraft their current position (ADS-B). These data evaluates my Home Server and forwards them to flightradar24 continue to contribute to the accuracy of the data there.
