Hi there, i recently moved into a place with roof terrace, and was looking forward to excellent ADS-B reception. I started test-installing my antenna to see how good it is. So far, i’m very underwhelmed.
I’m in São Paulo, Brasil.
I’m quite close to Congonhas airport (< 2 miles).
I’m very close to the flightpath of incoming airplanes (~0.5 miles?).
I’m also close to two (i think) cell sites, both on top of neighboring buildings.
My antenna is LOS to incoming aircraft, but my Pro Stick Plus does not pick up their messages. It does pick up some messages from aircraft further away (5 to about max 100 miles), although reception is spotty at best (i get like 10 messages/s on a good day)
Now i don’t know much about antennas, signals, frequencies (much of what i read here sounds like gibberish to me hahah), i’m quite the noob. Is there anything i’m doing wrong? I’ve read that cell towers might interfere with reception, and i have two close by. Can i do anything about that? I’ve read about band filters? Can this help? Is there anything else i’m missing?
Thankful for any tips! Thank you!
