Evidence Guide

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

Evidence of the ability to:

  • assemble, install, align and test a satellite antenna according to plans and specifications, and site specific safety requirements
  • conduct performance tests according to manufacturer's specifications and enterprise guidelines.

Context of and specific resources for assessment 

Assessment must ensure:

  • suitable site for satellite antenna installation
  • range of antennas and cables currently used in industry
  • range of general and test equipment required for satellite antenna installation and testing.

Method of assessment 

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

  • direct observation of the candidate installing a satellite receiving antenna given the satellite details and the satellite antenna coordinates
  • direct observation of the candidate preparing, securing and connecting a cable to the satellite antenna
  • direct observation of appropriate signal performance measurement and adjustment of azimuth, elevation and polarisation alignment
  • oral or written questioning to assess required knowledge.

Guidance information for assessment 

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

  • ICTRFN2164B Install a terrestrial antenna
  • ICTDRE3156B Install digital reception equipment.

Aboriginal people and other people from a non-English speaking background may have second language issues.

Access must be provided to appropriate learning and assessment support when required.

Assessment processes and techniques must be culturally appropriate, and appropriate to the oral communication skill level, and language and literacy capacity of the candidate and the work being performed.

In all cases where practical assessment is used it will be combined with targeted questioning to assess required knowledge. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency.

Where applicable, physical resources should include equipment modified for people with special needs.
