Hello there. I,m about 6 km east of Brantford and 17,s signal is a lot weaker after they moved from 43 to 31. I emailed channel 17 and one of there engineers emailed me and said CITY also on 31 in Woodstock was interfering with there signal from Buffalo. They are not telling me the truth. I updated my antenna with a channel master 2020 and upgraded my coax. Now I receive it about 90% of the time. At this moment in time I am receiving the signal at 80 on my signal strength meter. I do not think the people I was communicating with were not familiar with receiving TV over the air. Hope this answers some of your questions.
