I was hoping that, since it takes terrain into account, it might be more accurate than other sites I've used. I'm in a bit of a valley and get zero channels.

I was hoping that, since it takes terrain into account, it might be more accurate than other sites I've used. I'm in a bit of a valley and get zero channels. Everyone near me that watches OTA has a antenna elevated to at least 20 feet. This lists 5 channels as "green." It also seems to use licensed ERP rather than actual ERP. There is a VHF station near me licensed for 300W that only broadcasts at 100W ERP; this site lists it as 300W.
