This premium RTL-SDR was designed, developed and fabricated by Nooelec in the USA and Canada in order to implement a wide array of feature requests. Compared to R820T-based devices, this E4000-based SDR excels at sensitivity at 500MHz and >1500MHz, and is capable of far higher frequencies, up to approximately 2350MHz.

The E4000 can tune up to 2.3GHz while the R820T2 tops out at about 1.7GHz (and sometimes has trouble locking towards the top end of its range). However the E4000 has a tuning gap between about 1.1-1.2GHz so it isn't a good choice for ADS-B.
