I have the Roamio Basic, and use it for OTA. I just moved to a new location, and I'm getting dropouts on some channels. I went to Tvfool.com and attached what they told me. I'm hoping somebody can recommend an antenna. This will be inside, but an outdoor antenna is not out of the question (I have an extra room for storage), I'll just need a way to keep it propped up. I contacted Solid Signal, and they told me reception isn't going to happen without a rotator, which obviously really doesn't work with a DVR especially one tuning 4 channels at the same time time. The channels I'm interested in are NBC, ABC, CBS, Fox, MyNetwork, and CW.
