As I write, the outside air temperature is -40 degrees Celsius outside and the Flightaware Pro Stick Plus up on the roof is still functioning. Here in Canada we measure temperature in degrees Celsius, however -40 is the temperature at which the Celsius and Fahrenheit scales cross, so no matter which scale you prefer, it’s still -40 outside. Fortunately, there is not much wind at the moment so the wind chill is ‘only’ -51C.
The dongle is plugged into a tiny Nexx WT3020 running OpenWrt and Dump1090-mutability, and between the dongle and the antenna is an LNA4ALL and a ceramic filter from Adam (9A4QV). The whole kit is mounted on the roof inside a 1/4 inch thick aluminum box, which is further protected by a poly amunition box. The antenna is a Heliax colinnear, with about 20 feet of 1/2 inch Heliax Superflex to the box.
Noise levels appear lower (min -42db), and sensitivity seems to be higher - more distant positions.
