I have a small flat wave antenna in the living room now, about 7 feet up. I get 3, 5, 15 and 55 at about 75% on the roamio, and it records fine of course. I get around 55 on 10, which is green, and it seems to be recording OK. I would like to see better performance from them.
My tv and directv am21 wont get 10 at all.
