I still have to look at the old line to see if its pinched/damaged it got dark out to check tonight.
Today's "over the air" broadcast channels are digital. They either have enough signal (and play); or they don't (and don't play). Corroded or damaged F connectors can "leak" signal to the point that only very strong signals get through. Slight imperfections in the cable don't have much effect on digital signals because to display on the TV they need to be pretty strong to begin with.
Cable however is analog. To separate the many cable channels sent down the coax cable each is assigned a frequency band. The lower the frequencies are less likely to be effected by signal loss than higher ones.
We used to have this same problem around here when I was younger "channel 3" would come in "OK" but 6 was real snowy and 10 did not come in at all. The fix was always on the roof where dad would cut off the old connector and put on a new one.
The fact that 2 of of 3 were OK on both TV and cable pointed pretty strong that the cable was the culprit.
