Hi.
To help out, I have a boxee box with a live tv reception dongle and can pick up 2 channels with the provided antenna, which is about 4 inches in height and 5 feet off the basement floor. My postal code is B4G 1A7 if you want to check out the reception challenges.
In the coming weeks, I will be putting up a 40' tower, another 15' on that, with a Channelmaster 4228hd antenna, a preamp and a 9521 rotator.
Will update when that is all done.
