My results also agree with this.
Shyte, I have just caught up with this thread.
I don't believe that the DCBCE would inform that all residents in a particular area will either be ok or not....they simply measure a few random areas and draw a map up from that..plenty of scope for hit n miss.
Proof of point is my location.
To use line of sight, path plots and the lot, your theorey says I am in an area to be served by Mt. Moombil, and the quantified DCBCE readings indicate a good quality signal availabe....even the digital ready site tells me that. I should get it all set up again professionally, prove it don't work again, and then present them with the installers invoice, as the official governmental site told me it would work on terrestrial where I live!!!
I debunked this theory by discussing my locations with broadcastaustralia, as well as by an authorised antenna installer doing measurements on site.
I am now a migrated from Aurora to VAST user, and no solid useable reliable signal will get me terrestrial to a user friendly level.
I can go 350 metres down the road, and use rabbit ears for reception.
You simply cannot use bearings and terrain to work out that you will be ok or not...in fact I got best digital terrestrial using a phased array antenna, pointing 90-100 degrees bouncing off of a mountain. This is why these pro blokes say that if you are in those situations, get some help. In real terms, the private have a go bloke looking to do a self install is likely to spend more money buying the wrong gear, using trial and eroor at a monetary cost for now useless junk, and would have saved his / her dosh getting expert advice or installation in the first instance.
I'm all for you offering advice, but tell people where you are, what your basing your assumptions on, guiding them to "roughtimates" or "whatifs" in a perfect environment of where to point and which possible antennas. But you must qualify this by saying local conditions could prove different at your particular residence...
