Over the past 9 months or so, I’ve been collating a lot of data from various ADSB receiver combinations, using RTL-SDR Blog v3, RadarBox and FlightAware dongles, and various antenna setups, with and without an LNA, with the long-term goal of doing a writeup on what I’ve found the best bang-for-buck combination to be (I won’t give away too much now, but the result are not what I expected!)
One thing that has frustrated me the most is the poor performance of the FA ProStick Plus. This performs worse than, to at best maybe on par with, a stock RTL-SDR dongle. This is in stark comparison to the RadarBox dongle which gives a very noticeable performance gain.
I’m using an up-to-date version of dump1090-fa, auto gain control (which I’ve used across all dongles, I live very close to an airport so I find that fixing my gain tends to overload as I see a lot of air traffic within only 1km or so) and at the moment, no LNA. Dongle was purchased from RTL-SDR Blog so I’m certain it’s genuine.
Setups are otherwise 100% identical, same Raspberry Pi, same software, same antenna, same cables, just swapping the dongles only.
Any other ideas or suggestions before I send this back?
