Intermittent signal drops are likely caused by local interference from other RF sources you fly over. As well as possibly directional RF / WiFi signals. Usually pushing forward for a few seconds resolves that issue as you pass through it. Another cause is if you're flying too low and you don't have clean line of sight between your Phantom and your RC Transmitter. That momentary obstruction can cause a weak signal or outage as well. Don't forget to have your antennas on your controller oriented correctly too, which means both antennas facing up to the sky with the side of the antennas facing your Phantom 3.
Good advice! However, it is a bit unsettling to be told initially that your primary helipad has a poor signal even before launch, when you know from months of flying that it is problem free, and it flies perfectly from there, even at distances of 2700 feet or more. During flight, dropping below LOS generating signal issues makes sense, as does climbing to regain signal and LOS.
