Australian DTTB Field Trial Summary ResultsCOVERAGE
Judgement of the coverage of DTTB compared to PAL is complex, as comparison has to be between a “cliff edge” failure of DTTB to a gradual failure of PAL.
A margin of safety has to be allowed, for DTTB reliable reception, further complicating decisions on equivalent coverage.
Coverage is also influenced by Receiver performance, especially NF.
