The coverage area of an ADS-B receiver typically spans about 200-250 km (125-155 miles) in all directions.
However, coverage can extend up to 400 km (about 250 miles) or more with an ideally placed receiver—especially if the antenna is installed at a high elevation with unobstructed visibility in all directions.
Several factors influence the actual coverage range:
Antenna Height: The higher the antenna, the greater the potential coverage. Elevated placements, such as on tall buildings or hills, can significantly increase range.
Obstructions: Mountains, buildings, and other physical obstructions can limit line-of-sight coverage, particularly at lower altitudes.
Atmospheric Conditions: Extreme weather, like heavy rain or snow, or specific atmospheric conditions (such as temperature inversions or dense fog) can slightly impact signal range.
In summary, well-positioned receivers provide the best possible coverage, helping to enhance the tracking network for Flightradar24.
