on this topic I talked about building my ADS-B receiver to feed
FlightAware and FlightRadar24. I got decent results but was waiting for
some final pieces to put the unit outdoors and attach the LNA and filter
(some ethernet cables and an antenna in the end).
I ended up buying a 1090MHz J-Pole antenna from eBay. I am super thrilled with it, the results are exceptional, shipping was fast and the price was right.
I think the ultimate results speak for themselves. Go look at the previous post to compare and I think you'll agree.
