Thanks videobruce. I am getting 2.1 very consistently. Actually just watching Red Wings vs LA right now
. 29.1 and 49.1 are also very decent. I get them most of the time except some night times.
The two channels that I don't get consistently are 4.1 and 7.1. If a better antenna or pre-amp will not help get those, I will stay with my current setup.
