power the Receiver. The internal battery can also operate as a UPS for up to
17 hours. A UPS protects the equipment from power surges and spikes, and
keeps the Receiver running during short power outages.
For more information, contact your local CHC dealer.
D.I.iv. LIGHTING AND SURGE PROTECTION
CHC recommends that you install lightning protection equipment at
permanent sites. All connections to the Receiver should have surge
protection. Typically, the minimum protection should include a surge
protector in the antenna feed line, on the Receiver's power supply system. If
serial devices are attached to the Receiver, those serial connections should
also be provided with surge protection. Also, protect any communications
and power lines at building entry points. If you use other antennas, such as a
radio modem that distributes real-time correction messages, install surge
protection on those antenna feeds as well.
No surge protection devices can offer protection unless they are connected
to an excellent ground using very low impedance conductors. Equipment
damage caused by electrical surges occurs in many permanent installations
even though surge protection is in place. Commonly, this is because the
grounding system used was designed to protect against AC electrical hazards
rather than to dissipate the sudden, high current surges caused by lightning.
Please consult with a lightning protection expert or research the topic when
planning permanent installations.
For more information, contact your local CHC dealer.
D.I.v. PLACING THE ANTENNA
The antenna location will have a significant effect on the quality of your
X360 Receiver's performance. In temporary developments it may not
always be possible to set up on an ideal location with an excellent sky view.
However, when installing a permanent station, be sure to plan the antenna
location and mounting system carefully.
The general requirements for the antenna location and mount are:
 Keep the distance from the objects that may cause the multipath effects
(such as buildings, trees, reflective surface) for at least 200 m (656 feet)
 Clear sky above 10 degrees elevation
 Away from electromagnetism interference region (e.g. Microwave
station, radio transmitting station, high voltage wires) at least 200 m
(656 feet)
 Mounted 1.5 m (5 feet) above any nearby signal reflectors.
