The predicted signal strengths are for antennas 10 m above the ground. This has been done to identify which areas which will need VAST coverage instead.
Perhaps, but unless theres a source, we dont know for sure.
As others have said they also use Urban. Suburban, and Rural areas and signal levels. Usually signal is usable below those levels anyway. So what may be a variable area @ 10m, may be crap by 8m, and unusable by 5m. Or may be variable at 10m and almost as good at 5m. Hence why you cant trust digitalready.
This is why James T et al were having a go at you in the thread relating to Bald Hill on the Sunshine Coast. Despite being blocked by a large stand of trees, being predicted for an unknown height (which you state is 10m now anyway), and despite local installer experience, you were suggesting Bald Hill over Mt Cootha, which had a single hill and less obstructions. Perhaps you were right and there is good signal at 10m AGL
. But thats hardly an easy option is it.
How many 10m antennas do you think go up these days anyway, I service the fringes of several transmitters, and I can tell you its not many at all (ie. big $$$$). Long gone are the days of high masts and massive guy systems.
