I've recently bought the BUNDLE ADS-B USB Dongle + "SCO-1090-MCX" Antenna (1090 MHz)(the one you can find on the Flightradar24 page in "Optional") and tried to install on the top of my roof, using the post of the TV antenna. What happened is really strange: I've first tried the antenna inside my house, just for test if it was working correctly and I got planes with a range of 30nm. Then I moved outside, on the roof and holding the antenna in my hand 2-3 meter distant from the post of TV antennas I was able to get planes in 50 nm range. When I placed the antenna in its final position (exactly parallel and adjacent the post) I got 0 planes. I was even unable to get an helicopter that was flying exactly over my house (FR24 found it). I think that the post (42 millimeter of diameter, iron) is in same way interfering in reception. On the post are installed 3 directional antennas (they looks likes Yagi Uda antennas) receiving frequencies around 700-800MHz.
Do you know if the are technical problem in my installation? If so, how can I fix them?
I've spent a lot of money on the antenna and i'm quite unhappy that I can receive only a few near planes. From range predictor of my installation I was expecting at least 200 nm of range.
I'm a beginner with antennas, so I not really know what are best practice to make the antenna receiving best possible.
PS: maybe there's a problem also from the raspberry side? I'm using an iPhone charger as power supply, inside was working correctly as I said, but maybe is not good for receiving all the signals.
Another thing I was not sure in settings is the gain. I've no idea what the value represent, I've just setted "max"
