New to Piaware (9 days in). I am in urban setting just north of downtown Dallas. I ran for the first seven days with the FlightAware ADS-B Dual 978 MHz + 1090 MHz Band-Pass SMA Filter installed directly off my Pro Stick Plus. After that, I decided to remove the filter and see what happened with the antenna attached directly to the Pro Stick Plus (everything else remained the same). Without the filter, my aircraft reported per day doubled, position reports went up 5x, and I went from seeing almost no traffic outside the 50-mile ring to seeing things out to 200-miles and beyond in every direction.
BUT without the filter, almost all the close, low-level traffic has gone away. I’m about 5 miles from Dallas Love Field, and I was getting incredible detail of departures and arrivals until I removed the filter. I still see plenty of low level traffic coming in / out of DFW without the filter (about 20 miles away). I’d love to understand “why” and find out if there is a way to get the best of both worlds?
My setup is:
Raspberry Pi 4 B running PiAware 4.0
FlightAware Pro Stick Plus
FlightAware ADS-B Dual 978 MHz + 1090 MHz Band-Pass SMA Filter
DPD Productions ADS-B Vertical Outdoor Base Antenna
RG8X Coax Cable (20 ft. N Male / SMA Male)
