We have a cabin in the woods in Northern Wisconsin, in the past we got some reception, 3 channels through analog but now with our convertor box, and substantial rooftop antenna we get nothing, our neighbor also get no reception. Only on two occasions did we get 5 stations about midnight, they were gone in the morning. Not sure what to think??? We do have large trees close by, but the stations coming in at late hours doesn't seem to make sense, there were no storms or weather issues that I know of. Any help here is much appreciated, as we'll be up again soon! Thanks.
