in extreme cases. Almost entirely useless for flight control
unless used with a ground station that can track your
flight, only really used in fixed wing extreme range cases
such as military UAV’s.
So, each of these can be 'seen' progressively further
away by the receiver.
The same can be said of the receiving antenna on the
quad its self. If it 'looks' for a signal in a limited area, it's
field of view being narrower means it can see the signal
from further away. Much like a fisheye lens, a naked eye,
binoculars and telescope depending on antenna type.
However if it turns away from the source of the
transmission with a high gain antenna it would be
completely uncontrolled or 'blind' using a dish or patch
antenna to receive with. Normally the best used is stick,
cloverleaf or mushroom type.
For instance the probes which NASA sent out, like
voyager, have no more power output than a regular
walkie talkie radio but because of the precision of the
sending and receiving 'antennas' (more like a laser beam
than a spotlight) it can be received from literally millions
of miles away. Of course it helps that there is
comparatively little interference to swamp out the signal
in space but you get the idea.
