Started out like most, with a Pi 3B+ and one of those magnetic antennas that they claim are tuned for 1090. Put it all on the windowsill in my bedroom because I really didn’t have any idea how it might turn out. Before long I had mounted the antenna to a 1 quart paint can. Then I made a cut-down mast. Then I bought the FlightAware antenna and hung it from a piece of string in my window. Then I added the FA light blue filter.
Finally, a little over a week ago, I moved it to the peak of my roof and routed 50 feet of “low loss coax” down to my garage (https://www.amazon.com/gp/product/B07RXWHG5X/ref=ppx_yo_dt_b_asin_title_o02_s01?ie=UTF8&psc=1).
Range is not only up, but more consistent. Total number of aircraft is up, Messages per aircraft is up, and for the last several days I have been at the top of my “Nearby Sites” stats. The antenna itself is only about 12 feet higher than before, but it has made a massive difference in the results!
