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:
conduct installation of a communications antenna according to plans and specifications
assess hazard levels at an RF site and apply knowledge of safety precautions for self, fellow workers and the public at large
mount antenna, connect transmission line and physically align antenna
use appropriate test equipment to perform a return loss sweep measurement or a measurement of forward and reflected power on at least two different antenna systems.
Context of, and specific resources for assessment
Assessment must ensure:
site for antenna installation
range of antennas and feedlines currently used in industry
range of general and test equipment required for antenna installation and testing.
Methods 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 communications antenna and adjusting its alignment
direct observation of the candidate preparing, securing and connecting a coaxial transmission line or waveguide to the antenna under test
review of sweep test reports completed by the candidate for two different antenna types
oral or written questioning of candidate to assess knowledge of antenna installation practices.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
ICTRFN3070A Install mobile telecommunication in motor vehicles.

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.
