Connector Operation

4-10
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.
No co-location with other radio transmitters is allowed. By definition, co-location
is when another radio device or it’s antenna is located within 20 cm of your
connector/transmitter and can transmit simultaneously with your UWTC unit.
Never install UWTC connector/transmitters within 20 cm or less from each other.
Never use your UWTC connector/transmitter as a portable device. Your unit has
been designed to be operated in a permanent installation only.
4.2.4 Antenna Connection
Your device has been shipped to you a standard antenna already attached.
You may remove and install Omega No. UWTC-ANT-LR high gain antenna
to improve range and signal strength if needed. This antenna is sold as an
accessory.
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.
Additional Information on installation and system operation can be found in
Section 6.
