List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
Elements | Performance Criteria |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Plan assembly of antenna system | 1.1 Arrange access to site according to required procedure 1.2 Apply all relevant legislation, codes, regulations and standards in planning process 1.3 Obtain relevant antenna specifications, requirements and radio communication site management book (RCSMB) from appropriate personnel 1.4 Organise appropriate installation personnel to be available on site 1.5 Assess relevant hazard levels from RCSMB and take appropriate preventative action according to prescribed safety requirements 1.6 Identify other antennas at site location and notify those who may be affected by outages 1.7 Inspect antenna system and feedline for physical damage before further work is performed 1.8 Organise tools and equipment and ensure they are in safe working order and adjusted to manufacturer’s specifications |
2. Assemble, mount and align antenna and prepare feedline | 2.1 Follow site specific safety requirements and enterprise work health and safety (WHS) processes and procedures 2.2 Assemble antenna system in safe manner according to manufacturer’s instructions 2.3 Mount antenna with correct azimuth and polarisation according to manufacturer’s instructions and work practices 2.4 Install radome to antenna if provided 2.5 Install lightning protection systems according to plans and specifications 2.6 Align antenna in horizontal and vertical planes to maximise signal |
3. Test antenna installation and document test results | 3.1 Conduct performance tests in safe manner according to manufacturer’s specifications and instructions 3.2 Record, interpret and compare test results with manufacturer’s data or design specifications 3.3 Confirm correct overall operation of antenna system |
4. Complete administrative tasks and clean up site | 4.1 Complete and store appropriate records and test results according to enterprise policy 4.2 Label radio frequency (RF) transmitter equipment and feedlines according to legislation 4.3 Notify all affected by outage that normal operation can resume 4.4 Clean, pack and store all tools and test equipment, and organise transport in suitable protective casing where appropriate 4.5 Restore any changes made to worksite to client’s satisfaction and obtain sign off |
Evidence of the ability to:
determine installation requirements and ensure site inspection activities are conducted prior to installation
conduct installation of a communications antenna according to plans and specifications
assess hazard levels at a radio frequency (RF) site and apply knowledge of safety precautions for self, fellow workers and the public
mount an antenna, connect a transmission line and physically align an 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.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
outline current industry practice for antenna installation including:
earthing
lightning protection
describe the procedures and equipment required for:
antenna sweep testing to measure return loss
measurement of distance to fault
measurement of feedline insertion loss
measurement of forward and reflected RF power
summarise features of instrument and equipment test methods and performance requirements
outline legislation, codes of practice and other formal agreements that directly impact on operation and testing of radio communications antennas and equipment
identify the general components and installation of antennas and feedlines
discuss the application of RF and electromagnetic radiation (EMR) standards and specific work health and safety (WHS) requirements
discuss the impact on the use and testing of radio communications instruments and equipment
identify the types of antennas that can withstand extreme environments
summarise typical issues and challenges that occur in telecommunications antenna installations.
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances should be typical of those experienced in the telecommunications – radio frequency networks field of work and include access to:
a site for antenna installation
a range of antennas and feedlines currently used in industry
a range of general tools and test equipment required for antenna installation and testing.
Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.
