hi abcd,
this thread is a really good idea - and your starting post was great! as you already know i did some antenna testing too- but never tried to built one myself. over the last months i bought 7 professional made antennas (4 different types) and 7 dongles (2 different types):
- flightaware 1090 26" link
- wimo gp-1090 link
- baz flu-sr y 13 yagi link
- jetvision sco 1090 mcx link
- jetvision a3 ads-b link
my finding was that the best receiving universal ads-b antenna is the jetvision a3 ads-b.
but what i never tried myself and always was really waiting for is a test selfmade vs professional made. in other words i’d find it extremly helpful to know how these different homemade antennas compare to e.g. the well known and widespread actual flightaware antenna?
thanks in advance
tom
edit: did not want to mess up your thread with lots of large pictures - so - here a small one with the ads-b mess that is left over
