Here's an example that I believe must be evidence of indoor multipath. I replaced a television that was having difficulties with one that is more than twice as big. Would reception change? I thought it might some, but here's what I've seen so far. I've done several scans. The antenna is the same. KVIE, which was the less reliable VHF, now is more so. Fox 40, which has been a problem ever since the transition in the room, won't lock. I have scanned it in. 42.1 was first scanned in on the old set more than 5 years ago. It was pretty much never locking. Today, I scanned it in. It locked with no problems. In the past 5 years, I've tried several antennas in this room. Even with more antenna gain, Diablo was a problem. Today, it wasn't. Maybe today was a perfect inversion for Diablo. We'll see. In addition, for the Walnut Grove signals, I've had to change location and height for both VHF and UHF channels.
