Have used the Adsb-x antenna outdoors and in attic. May be hard to compare 1090 and 978 due to the lower traffic levels on 978 and lower powered aircraft transmitters. The FA and AirNav dongles seem comparable. The AirNavs are physically smaller and the small plastic case can be easier to damage from bending.
Have noticed that the outdoor ADSBX antenna just above the roof receives TIS data from the airport about 10 miles away. Would be interesting to try decoding FIS.
The in attic antenna sees an average of 0 UAT and max 2, avg range 2.7nm and peak range 56. The outdoor antenna sees an average of 2 UAT and max of 8 avg max range 13.6 nm max range 142. For comparison on 1090 the same outdoor antenna sees avg 78 aircraft and max 211, avg max range 127, max range 202 nm. Probably higher altitude for 1090 aircraft. Don’t know if that’s typical for 1:10 ratio of UAT vs 1090 traffic.
