Installation
Mount the device to the pole in such way to direct the antenna directly into receiver
location.
Attention
: Transmitter’s antenna need to have clear line of sight with receiver’s
antenna (example of installation is shown below).
Connect the video signal cables to the BNC socket.
The length of the coaxial cable with video signal should not exceed 50m.
Attention: use only high-quality 75
Ω
coaxial cables, for example RG6.
Using UTP 100
Ω
cables it is necessary to use high-quality matching
transformer (Balum) Remember that every transformer or its passive video
converter cause video signal loss. With signal loss through the air, the level
of the signal may be visibly lowered.
Set up the working channel. Antennas polarisation (vertical installation) and the number of
the channel should be the same in both cooperating devices.

WARNING
To ensure stable radio range, the antennas need to have clear line of sight.
It is necessary to ensure full optical visibility in the first Fresnel zone. With
5.8GHz frequency and 400m distance you need to ensure at least free 3.2m
radius of space (r in the dr point) for radio beam.
