Thanks guys. I will be very interested to hear if the signal strength with an amp would be positive or negative (in my sitituation).
As for 31.2 doing a simulcast of fox. I asked a neighbor with a small, cheap, indoor antenna facing Harrison, which is 13 miles away and she does not get it. I did see the info indicating its there but perhaps it is no longer or the info is wrong. It checked krbk 49.1 web sight to see if they mention it and I didn't find anything. But they do show they use six towers in various locations. The tower in Forsyth, mo would be 36 miles away, so I should be able to get that I hope.

Anyway I'm optimistic enough that I can receive abc, nbc, fox, and cbs that I think I should order the antenna and then we can actually talk about real results. Thanks again for your time and help. I have learned a lot.
