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 terrestrial antenna according to plans and specifications and site specific safety requirements

conduct performance tests according to manufacturers specifications and enterprise guidelines

Context of and specific resources for assessment

Assessment must ensure

site for antenna installation

range of antennas and coaxial cables currently used in industry

range of general and test equipment required for 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 directional receiving antenna with a given direction of polarisation

direct observation of the candidate preparing securing and connecting a coaxial cable to the antenna

direct observation of appropriate signal performance measurement and adjustment of azimuth 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

ICTRFNA Install a satellite antenna

ICTRFN2163A Install a satellite antenna

ICTDREA Install digital reception equipment

ICTDRE3156A Install digital reception equipment.

Aboriginal people and other people from a nonEnglish 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
