I am very interested in this topic, My big problem is I have both weak & strong OTA signals, if I amp the weak ones my tuners overloads on the strong ones (unlike the analog days). I believe this should be a #1 priority in new designs of DTV tuners.
FYI...
I came across this article regarding the development and prediction of the future of the TV tuner industry.
