I don’t know of any indoor antenna that will work well. It all depends on the height of the antenna and obstructions. Any trees or buildings in your way will degrade your signal. We started with a fairly expensive flat one you hung on the inside wall. This worked no better than a $12 set of rabbit ears. Then put a standard antenna in the attic. This worked better but even the framing members and the shingles degraded the signal. We then moved it outside to the roof and now we are told this is as good as we will get without putting it up higher on a pole. No rotor was needed as all our station transmitters are fairly close together. In the end we were quite satisfied and don’t pay anything to watch tv.
