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 manufacturer's 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:

ICTRFN2163B Install a satellite 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.
