About 4 months ago, I installed an antenna in my attic. it is connected through a multiplexer that feeds multiple jacks throughout the house. I have been getting near flawless reception for more than 70 channels for months.
Just recently, I have lost a lot of the ABC Channel 13 signal. All other channels are still near perfect. No modifications or additions have been made. It is still the same TV. I went ahead and rescanned the channels but this did not help. Any idea what could be causing this selective interference all of a sudden?
