⚠️
It is dangerous to continue flying the drone below 12 V. This could result in damage
to the battery and the risk of the drone crashing.
Aircraft Antenna
The antennas of the aircraft can be oriented either upwards or downwards to maximize
reception in different situations. The SplashDrone 4 has an effective range of 5 km. Due
to the way radio frequency travel, when flying 0.5m above the water, the transmission
range reduces to 2.8 km. For the drone floating on the water surface, the transmission
range reduces to 500m.
Antenna Position
Generally, upward-pointing antennas improve reception when the drone is floating or
flying close to the water surface. Orienting the antennas downwards maximizes range
for higher altitude flights. Adjust the antennas' orientation to maximize range for your
flight plan.
Antenna oriented upward: Improves
reception when the drone is floating
(boat mode) or flying close to the water
surface.
Antenna oriented downwards: Improves
reception when the drone is flying further
away or fly at a high altitude.
To adjust the antenna position: loosen the antenna nut, adjust the antenna position, and
retighten the nut.
Antenna Blind Spot
Due to the nature of antenna radiation pattern, there is a blind spot about
40
°
under the
aircraft. When position under the blind spot area, the remote controller will experience
signal lost
. If you encounter signal lost issue when you are near the aircraft, you might
be in the blind spot area.
