Owner's manual

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 End Device 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 End Device and receiver, the devices can be raised
on one end or on both ends to hopefully clear the Fresnel Zone of obstructions.
No co-location with other radio transmitters is allowed. By definition, co-location
is when another radio device or the device’s antenna is located within 20 cm of
your connector/transmitter and can transmit simultaneously with your unit.
Never install multiple End Devices within 20 cm or less from each other.
Never use your UWXL End Device as a portable device. Your unit has been
designed to be operated in a permanent installation only.
3.2.3 Antenna Connection
Your End Device has been shipped to you with a standard antenna already
attached. In some cases the user may wish to install a remote antenna to
maximize transmission range to the receiver. In these instance the UWXL-RAK
antenna kit can be used. The kit includes a direction antenna, 8” extension cable
and a mounting bracket.
Use of any other antenna then what’s supplied with your End Device will void all
FCC, and IC regulatory compliance.
Additional information on installation and system operation can be found in
Section 6.
