The TV Fool report you've posted does not suggest easy reception of any signals from Mt. Wilson. The HD7697P mounted at 40' is doing quite well.

For example, KNBC is shown as having a noise margin in the air of -8.6 dB. The path profile shows the expected obstructing terrain. Virtually all the LA signals have adjacent and co-channel interference warnings. When I plug the numbers in to the calculator, assuming 100' of coax and no splitter, you theoretically could see KNBC but you have no margin for any interference or fading.

A die hard DX'r would consider stacking two or four long boom Yagis but still expect intermittent reception of most LA signals.
