Well, I made my franklin antenna and finished my system. Believe or not, my position reports grow from about 110/5min to 320/5min on FlightAware! My range still the same, but I use to see about 12 and max 15 aircrafts at same time on my radar. Now, I see about 25 all the time and I got 33 last...
Uow! There are sooo many antennas that I'm lost.
What antenna do you think is the best for outdoor use and build? I'm thinking to build franklin co-linear with wire of 1.65mm. I'll use with an 1090 filter and LNA (homemade with PCB).
