My cabling is not 25 years old as I changed from 300 ohm about 10 years ago.
I have weather boots on all my exterior connections and had changed nothing prior to the incident that caused the channel losses.
Channels I recieved prior to the recent issue:
2.3.5.6.7.10.12.22.33.44.57.
Now I can get 3,5,6 ( but I have to rotate the antenna) 22,33, and44.
As for the antenna I don't know what model it is, but it looks like an Antenna Craft C290 with only 10 "rear " elements and without the smaller elements between the larger ones at the rear.
I chatted with someone from Solid SIgnal who mentioned that the Canadian stations could have changed their footprint. Don't have a clue as to what that is.
