DISCONE

BASE STATION ANTENNA

INSTALLATION GUIDE

NOTE : The installation, performance testing and maintenance of this antenna must be undertaken by 

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.

Delivery

Â

Upon delivery, unpack the antenna carefully and 

check the contents

 against the packing slip.  It is most important to inspect the 

antenna to ensure that no damage has occurred in transit and that all items ordered are present.

Â

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.

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.

Model and Frequency

Â

The model will be marked on the label to be found adhered to the antenna.

Â

This label will also state the frequency range for which your antenna has been tuned.

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.
