I have an HD home run as well and sometimes the "signal strength" bar can be deceiving. I think your signal is too weak or your signal is weak combined with too much noise and your tuner can not get a lock.
The station you want has a strong signal from the TV fool plot but it's not line of site so it's probably distorted some what by bouncing off some obstruction. Fifty feet of coax is also a long run so your going to lose a lot of signal.
I'd try a preamp. You can probably get away with a cheap one and that might boost up the signal enough for your tuner to get a lock.
