, advise the cartage contractor and make appropriate notes on the delivery docket
before signing. if possible, any damaged items should be photographed. Then contact ZCG Scalar immediately.
Â
Store the antenna in a safe location away from vehicular traffic. Ensure materials are kept dry, and if necessary cover materials with
a water proof cover to prevent water ingress and damage.

General Precautions
Â
At all times standard OH&S working conditions must be maintained. Use common sense during all installation work.
Â
Never install an antenna where contact with electrical power lines is possible. Serious injury or death may occur. Power lines,
telephone lines and guy wires can look the same. Assume any wire or line can electrocute you.
Â
Always wear an approved safety harness when climbing an antenna mast or working on a raised platform where a fall could occur.
Â
Always take heed of all RF Electromagnetic Radiation Hazard Warning Signs which appear at the installation site. Never work where
contact with live antennas is possible.
Installation
Â
The antenna must be mounted clear of other antennas and any metallic objects which may cause interference or distortion of the
radiation pattern.
Â
The antenna should be secured using ZCG Scalar recommended clamps, or an equivalent. Take care not to over-tighten the clamps
beyond reason.
Cable and Connectors
Â
The antenna feeder cable should be secured so as no stress is placed upon any connections.
Â
Ensure that connector mating surfaces are not damaged and are clean and dry. The male connector pin should be set so as to not
damage the female connector pin. Tighten the connectors firmly and make sure they are seated correctly. The connection should be
sealed with two layers of self-amalgamating tape to prevent ingress of moisture.
Â
The feeder cable should be earthed to avoid a destructive power surge in the event of a lightning strike.
Return Loss Test
Â
Following installation of feeder cable, measure the return loss at the feeder cable input and check that there is no major departure
from the factory specification.
Power Up
Â
Commence the power up by applying low power to the antenna. Monitor the forward and reflected power at the transmitter.
Progressively increase the power to full power and monitor the forward and reflected levels.
Â
Only operate the antenna at the specified power levels. Exceeding the stated power levels will invalidate the warranty.
Â
REMOVE TRANSMITTER POWER IMMEDIATELY IF ANY ADVERSE CONDITIONS ARE DETECTED.
Maintenance
Â
The antenna and its components have been designed for high reliability and low maintenance. We recommend a routine annual
mechanical inspection of the antenna, connections and feeder cable, together with a check of the return loss.
