guys

my channel 9 sucks on 2 out of 4 tvs
had a guy a know redo the antenna last year, seemed ok at the time (took my amp down)

ch 9 has 91 strength but 0-25 quality when it mucks up, really only use this tv @ 5.30 pm weekdays (millionaire)

could putting a masthead amp back up fix it? or i need to pay more money out
