This is a bit of a tangent, but there are actually only 2 broadcast towers (well, I suppose you could argue 3 but 1 is only a backup so it just gets used when the big one is being serviced). As of two years ago, only the CBC site had a tv antenna, but I can see the CHUM tower has what looks to be a tv antenna on top of their tower now too (presumably CTV is transmitting off that one). Anyhow, not that it really matters. TV is quite high frequency though, and digital transmitters actually broadcast a much lower power levels than the old analog ones, so it becomes somewhat even more line of sight. But the nice thing with digital tv is that you can get very clear reception with a much lower signal. I think the coolest thing about ATSC is that it's both modulated in amplitude and frequency. We are about to start building tv transmitters at work actually.Fishdisease wrote:I had a commercial antenna and it was only picking up about 40% signal at my house - I'm in a forested area and on the wrong side of a large hill that blocks signal from the three broadcast towers that are in Clayton Park.
Anyway, after that ramble, I guess the real relevant point is if you hope to watch digital tv over the air, you need to have a decent path to the tower for a good signal.
