Introduction

The Wireless Video Link includes both transmitter (TX) and receiver (RX) modules, working in the ISM 

frequency band of 5.8GHz (5725-5865MHz). Analogue modulated video signals are sent wirelessly by 

the TX module to the RX module, and then the video signal will be demodulated and sent to a display.

There are 8 wireless channels can be selected when you are using this product. These channels are:

CH1-5705MHZ, CH2-5685MHZ, CH3-5665MHZ, CH4-5645MHZ, CH5-5885MHZ, CH6-5905MHZ, 

CH7-5925MHZ, and CH8-5945MHZ.

The characteristics of this product are: small size, low power consumption and high sensitivity. The 

product can be used in many applications requiring wireless video communication. When it’s used in the 

aero-modeling hobby, the Wireless Video Link TX will be mounted to the aircraft and the Wireless Video 

Link RX is connected to a display screen, allowing video signal wireless transmission.

Important:

 The antenna MUST be connected before power on, otherwise electronics damage may occur

 Make sure the antenna head of the video TX is pointing down, and the antenna head of the RX is 

pointing up. Make sure there is no obstacle between antennas; otherwise the communication 

range will be reduced.
