HDTV Signal Reception Expectations
Very different frequency in use between those sets of channels, the working ones are 1/3rd the frequency of the ones you are not seeing, and the friis transmission equation says that right there is a 9dB increase in path loss. 

Also your little spreadsheet shows some 20 odd dB difference in strength, not fully explained by the path losses.

What aerial setup are you using? Some sort of log periodic? Difficult to see much else that would cover that bandwidth well.

Personally I would be thinking of stacking a pair of yagis (One for each band of interest, and spaced at least a meter or so apart) and combining them with a suitable combiner, the combiners losses should be easily made up by the antenna gain, and using something tuned to the bands of interest will also help. 

You will certainly want the aerials outside and as high as possible, roofs are good, if you can get the things well clear of surrounding metalwork.
