Note that this is 1090ES only. My attempts to get UAT signals on an RTL2832U with E4000 were unsuccessful so far. Required bandwidth is too great for the available sample rate of the chipset.
BTW, the E4000 in my dongle has an L-band gap between 1079 and 1237 MHz and thus cannot be used for 1090ES. You need to buy a bunch of those $20 things (in reality more like $35) from different suppliers until you find one that works. You know how eBay operates.
