Repeater Mounting and Installation

6.2 Installation
When installing your repeater it is important to position your device in such a
way as to optimize the antenna location within what’s known as the “Fresnel
Zone”.
The Fresnel Zone can be thought of as a football-shaped invisible tunnel between
two locations that provides a path for RF signals between your
connector/transmitter and your repeater, as well as between your repeater and
receiver.
Figure 6-2. Installation
In order to achieve maximum range, the football-shaped path in which radio
waves travel must be free of all obstructions. Obstacles in the path (especially
metal) will decrease the communication range between your
connector/transmitter, repeater, and receiver. Also, If the antennas are mounted
just barely off the ground, over half of the Fresnel zone ends up being obstructed
by the earth resulting in significant reduction in range. To avoid this problem,
the antennas should be mounted high enough off of the ground so that the earth
does not interfere with the central diameter of the Fresnel zone.
It is important to understand that the environment may change over time due to new
equipment or machinery being installed, building construction, etc. If new obstacles
exist between your connector/transmitter, repeater, and receiver, the devices can be
raised on one end or on all ends to hopefully clear the Fresnel Zone of
obstructions.
Never install UWTC transmitters, repeaters, or receivers within 20cm or less from
each other.
Never use your UWTC repeater as a portable device. Your unit has been
designed to be operated in a permanent installation only.
