Receiver Operation

5.2.2 Installation

When installing your receiver 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 receiver.

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 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 and receiver, the devices can be raised on
one end or on both ends to hopefully clear the Fresnel Zone of obstructions.
5.2.3 Antenna Connection
Your receiver has been shipped to you with a high gain antenna already
attached.
In some cases, a short RF cable may be used to connect an antenna to your
device. Please note that RF extension cables will always add some loss to the
transmitting signal strength. The longer the cable the more signal will be lost
over that cable. Because of this the length of the cable should be kept as short as
possible.
Use of any other antenna then what's supplied with your device will void all FCC
and CE regulatory compliance.
