It is recommended that install the antenna at least 25cm away from the HDMI
source/cable. A good shield HDMI cable can be a resolution too. The following shield
HDMI cable uses 360-degree shield termination, which is recommended practice.

RF cable connector/Antenna connector check
Before flight, check if the antennas are connected to the modules. Running module
without antenna connected results in very short range and potentially can damage the
module. It is recommended to check the connection of all RF connectors. Loose
connection can degrade the range significantly.
Antenna placement
Place the two air antennas so that no matter what position the drone is, at lease one
antenna is not blocked by the payload from the ground station.
If the drone will fly in full throttle, it will lean forward. Install the air antenna so that it is
close to be vertical to the ground when the drone moves forward in full throttle.
Battery level of ground station
The reception performance will degrade if the battery of ground station runs low, even
though it might still power the wireless ground unit up.
