Before you guys run out and start buying preamps that live NW of the CN tower, when the DTV stations start fireing up, you will probably have a problem with overload since it (CN tower) will be in line with the US stations!
I know, I have a MAJOR problem with the 3 on that 'foreign country' of Grand Island interfering with 19, 41 & 47! BTW, that's why WNED erected their antenna where it is now, so we can't receive ch 19! No pledge $$ for Canada!
Free, abundant OTA television separates this country from many others. ATSC1 has only been in force since 2009. The wireless industry has enough spectrum. Enough of 'planned obsolesce'.
