I’ve had my ADS-B up and running for a few weeks now and have upgraded the antenna to a flightaware 1090 and mounted on the roof. The difference is incredible in both aircraft being picked up and distance. I’m using 2m of Aircell 5 coax from the antenna to the Pro stick plus then a USB extension cable from dongle to Raspberry Pi. Here is a short video for the switching over from the standard antenna to the flightaware one. Hope this helps with anyone wanting to upgrade their antenna
What can one say? Quite an improvement! Congratulations!
