Coverage evaluation matrix The following table references typical terms used in this report as a description of digital coverage and reception. As these terms have specific technical and engineering definitions, the table has been prepared to provide the reader with a reference point. Category Coverage description Affected services Evaluation Description of strength Reception quality No issues Strong All Suburban + 12 dB threshold n/a Very good Suburban + 6 dB Above threshold n/a Good Suburban Above threshold n/a Potential issues Adequate At least one below suburban threshold Rural threshold While adequate coverage should provide good signal reception over an area, some statistical signal variations could potentially cause occasional reception difficulties. The rural notional receiving system with 10m antenna height* may be required in some areas to avoid digital reception issues. *As defined in the Digital Terrestrial Television Broadcasting Planning Handbook, the ABA, 2005. Issues Poor At least one below rural threshold Below rural threshold Isolated^—affects less than approximately 5% of the populated area. Patchy^—affects between approximately 5% and 25% of the populated area
height) may be required for reliable digital reception. Bombala transmitter does not provide a full set of digital services (no SBS and CBN). Broadcasters do not plan to implement SBS digital services. Prime (CBN) digital services are yet to be implemented and are expected to provide similar coverage as the measured digital services. Coverage/reception issues Berridale (5 measurement locations) 844 Cooma/Monaro transmitter provides coverage ranging from poor to no coverage Cooma/Monaro transmitter provides no reliable coverage as the town is located at the coverage fringe. Cooma/Monaro transmitter does not provide a full set of analog and digital services (no SBS). Broadcasters do not plan to implement additional digital services. Berridale retransmission site does not provide digital services. This site is not on the broadcasters’ candidate list for conversion. Bungendore (11 measurement locations) 2,183 Canberra transmitter provides coverage ranging from adequate to no coverage Canberra transmitter provides no reliable coverage in this area as the town is located at the coverage fringe. Burra Creek (10 measurement locations) 181 Canberra transmitter provides coverage ranging from poor to no coverage Canberra transmitter provides no reliable coverage in this area as the town is located at the coverage fringe. Burra Creek retransmission site does not provide digital services. This site is not on the broadcasters’ candidate list for conversion. Captains Flat (3 measurement locations) 447 Canberra transmitter provides coverage ranging from poor to no coverage Canberra transmitter provides no reliable coverage in this area as the town is located at the coverage fringe. the time measurements were taken, the Captains Flat hybrid site did not have all digital services implemented. Three commercial services are yet to be implemented. Two national retransmission services are not on the broadcasters’ candidate list for conversion. Dalton (1 measurement location) <100 Canberra transmitter provides poor coverage Canberra transmitter provides no reliable coverage in this area as the town is located at the coverage fringe.
