Thank you in advance for any help offered.
I'm a complete newcomer to Raspberry Pi and ADS-B. I have a little experience with HF antennas and a good basic understanding of electronics and RF.
I've followed the tutorial from abcd567 on heatmaps and generated the attached file.
My system: RPI 3b+ running Buster
Dongle is flightaware prostick plus, the blue one.
Ant1 is a Discone at 105 feet above sea level, this was my first antenna and I was receiving out to 86 nautical miles
Ant 2 is a 10 element Collinear for 1090 at a 103 feet above sea level, I had hope to see some improvement with received distance, this has dropped to 66 nautical miles. However, I have noticed improved reception from lower flying aircraft.
The scan image is from Antenna 2 as I want to run the Pi totally independently from an SDR I use that uses the Discone. Would one of the forum members have a look at the scan and see if there are any issues that need filters adding to correct them, please.
Best wishes from Liverpool UK
