experienced personnel only. ZCG Scalar disclaims any liability or responsibility for any event whatsoever
which occurs as a result of improper or unsafe installation practices.

If there is any damage or any item is missing
, 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.
Store the antenna in a safe location away from vehicular traffi c. Ensure materials are kept dry, and if necessary cover materials with
a water proof cover to prevent water ingress and damage.
Model and Frequency
The model will be marked on the label to be found adhered to the antenna.
This label will also state the frequency range for which your antenna has been tuned.

General Precautions
At all times standard OH&S working conditions must be maintained. Use common sense during all installation work.
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.
Always wear an approved safety harness when climbing an antenna mast or working on a raised platform where a fall could occur.
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
Assemble the Yagi as per the diagram and instructions to be found on the next page. The antenna must be mounted clear of other
antennas and any metallic objects which may cause interference or distortion of the radiation pattern.
The antenna should be secured using ZCG Scalar recommended clamp, or an equivalent. Take care not to over-tighten the clamp
beyond reason. A strut kit is recommended to support the boom.
Cable and Connectors
The antenna feeder cable should be secured so as no stress is placed upon any connections.
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 fi rmly and make sure they are seated correctly. The connection should be
sealed with two layers of self-amalgamating tape to prevent ingress of moisture.
The feeder cable should be earthed to avoid a destructive power surge in the event of a lightning strike.
Return Loss Test
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 specifi cation.
Power Up
Commence the power up by applying low power to the antenna. Monitor the forward and refl ected power at the transmitter.
Progressively increase the power to full power and monitor the forward and refl ected levels.
Only operate the antenna at the specifi ed power levels. Exceeding the stated power levels will invalidate the warranty.
REMOVE TRANSMITTER POWER IMMEDIATELY IF ANY ADVERSE CONDITIONS ARE DETECTED.
Maintenance
The antenna and its components have been designed for high reliability and low maintenance. We recommend that you conduct a
routine annual mechanical inspection of the antenna, connections and feeder cable, together with a check of the return loss.
