I have been experimenting with Satnogs for some time and it is really fun although since my beginning in this adventure I have always had the same problem. I currently have a vertical dual band antenna in a really bad location, but at the moment I can’t change it. The rest of the system consists of a Raspberry and an SDR. Unable to have good signals, I decided to buy an LNA and the results were bad. Only with the antenna and the SDR does everything as good as possible with the location of the antenna work, but when I install the LNA I stop receiving almost completely. I have tried with 2 SDR (rtl-sdr.com and with Nooelec Smartee, also with 2 different LNAs (SPF5189Z and another one that I don’t remember the model) with the same bad result. I have also tried this same configuration in windows and it works fine. can anybody help me?
Thank you in advance
