Select antenna system for radio communications

Assessment tool

Version 1.0
Issue Date: May 2024


This unit describes the skills and knowledge required to interpret industry practices and theories, and select appropriate antenna equipment for small projects or parts of larger projects to a job specification.

It applies to individuals working alone or responsible for a technical team within regulatory authorities or other private and public organisations where they combine technical radio communications skills with broader organisational and administrative skills.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

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. Prepare to select antenna system

1.1 Establish extent of project from design brief or specification within team environment

1.2 Obtain and review plans and drawings of existing or proposed installation site

1.3 Determine whether antenna system hardware requires secure hut or shelter

1.4 Determine antenna requirements and antenna feedline requirements from design brief or specifications, and research available commercial products

1.5 Determine earthing components to meet regulatory and earthing requirements of antenna system

1.6 Prepare antenna feedline route to comply with job specifications and regulatory requirements

1.7 Identify installation options, and assess against performance requirements and client requirements

2. Select antenna system

2.1 Evaluate potential antenna system solutions that satisfy required performance, budgetary and regulatory requirements, and are suitable for installation in specified environment

2.2 Make recommendations and select optimum antenna system

3. Document antenna system selection

3.1 Document calculations, final specifications and reasons for selection of antenna system

3.2 Prepare final report, including documentation and drawings of selected antenna system, and distribute to appropriate persons in accordance with enterprise policies and procedures

Evidence of the ability to:

identify the antenna installation parameters

select an antenna system required to meet the parameters

determine the feedline installation from design and specifications

document the recommendations for the antenna system selection

comply with specifications and regulatory requirements.

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:

describe the principles of antenna wave propagation and the impact on antenna array design

describe the principles of transmission line design and operation, and the impact on antenna design and installation including:

allowable loss in dB

characteristic impedance

mechanical characteristics

method of securing

radio frequency (RF) connector type

weatherproofing.

describe the process for selecting an antenna design based on the application and performance requirements

identify and describe a range of antenna systems

summarise specific issues related to antenna installations and the creation of particular radiation patterns

identify and describe the regulatory and industry standards relevant to 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:

antenna resources such as manufacturers’ data sheets, specifications and catalogues

transmission line resources such as manufacturers’ data sheets, specifications and catalogues.

Assessors of this unit must satisfy the requirements for assessors in applicable vocational education and training legislation, frameworks and/or standards.

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
