Hi Todd, With the standard FLARM antenna, the range is about 3 or 4 km and the current firmware also limits it to 5 km in horizontal range and 1000m vertical range I think. The next version of the firmware will open that restriction and with a high gain antenna on the ground, the range should reach 10km or so. Of course, it's best for everyone if the units are installed properly.
