2.1 Installation notes
2.2 Attention
WKRC-H15 All-in-one HD GCS Remote is an all-in-one high-definition image transmission device with a bright display.The maximum
communication distance is 6km, and it supports local HD video shooting and recording. WKRC-H15 includes the sky end and the
ground end, works in the 2.4GHz frequency band, and can transmit video images, flight control system signals and ground end control
signals through wireless communication. Please ensure that WKRC-H15 is used in compliance with local laws and regulations. Please
read this manual carefully before use.
When using WKRC-H15, if the operation is improper, the aircraft may cause a certain degree of injury and damage to the person and
property. Please pay attention to safety when using it.
(1) Be sure to use spare parts provided by Walker.
(2) Be sure to install the antenna before powering on to avoid circuit damage.
(3) Try to keep the antenna at the sky end free of entanglement and unobstructed objects. The end of the antenna is vertically downward
and free from bending, to avoid shortening the communication distance due to the blocking, or even unable to communicate.
(4) When installing the sky-end antenna, pay attention to the antenna separation as far as possible to achieve better diversity. At the
same time, try to stay away from the large metal structural parts. Choose a location that will not be blocked in flight for installation.
(5) During the installation, pay attention to keep an appropriate distance between the electronic devices, so as to reduce the
electromagnetic interference between the devices to a minimum.
(1) Before use, make sure that all connecting cables are firm and reliable, and the interface is correct, then turn on the power.
(2) Make sure that no foreign objects (such as liquid, sand, etc.) enter the components.
(3) Please check the power on the ground before use. If the power is insufficient, please charge in time.
(4) Please check the surrounding environment to ensure that there is no interference from other 2.4G devices. Otherwise, the video
transmission performance may be affected.
(5) Please pay attention to the angle and direction of the ground-side antenna during the flight. When the signal on the ground side is
poor or the image quality is not good, adjusting the tilt of the antenna on the ground side may have an improvement effect.
(6) For supporting electronic equipment, please select products with better electromagnetic shielding performance.

4.0 Installation of modules on the ground, sky, and flight controllers
4.1 Install and adjust the antenna on the GCS Remote end of WKRC-H15
Install the antenna and adjust the position of the antenna on the ground.
The signal strength received at different antenna positions is different.
Note: When maneuvering the aircraft, make sure that the aircraft is in the best communication range. Adjust the azimuth or distance
between the operator and the aircraft in time to ensure that the aircraft is always within the optimal communication range.
Best communication range
Do not use other communication
devices in the same frequency
band at the same time to avoid
interference with the GCS Remote
signal.

Precautions
1) Be sure to install the antenna before powering on to avoid damage to the circuit.
2) When using, try to keep the antenna facing down and obstructed by obstacles, to avoid the communication
distance being shortened due to blocking, or even unable to communicate.
3) Be sure to install and use the original antenna correctly. It is forbidden to use other antennas.
4) If the aircraft used is large, it is recommended to use the sky antenna extension cable to connect the sky
terminal and the sky antenna.
4.5 RX-H15 sky end installation antenna
The sky side needs to communicate with the ground side through the antenna.
Please install the antenna as follows:
1. Install the sky antenna extension cable to the sky antenna port as shown below.
2. Use foam double-sided tape or other methods to fix the sky end to the reserved position of the flight platform or other suitable
flat surface, tighten the antenna to the antenna extension cable.
