It depends on place to place in city it's enough but in villages it's not I remember in my maternal village we used to place antenna on 2nd floor to get signal and if any signal lost we used to think that
power cut might happen at the place where tower is situated. Don'tknow wether it's true or not
One more interesting thing happened we used to get a channel feed from Pakistan between 8 am to 12 pm. It was ARY i guess.
