I don't know where you heard this, but I really doubt it.  This would 
just create a large interference pattern making the signal basically 
useless.  The way cell phones work is that neighboring towers use 
different frequencies so as to not interfere with each other, with 6 
MHz wide TV signals this would not be at all practical.  And it would 
be impossible to keep signals in phase over 6 MHz if neighboring 
signals were on the same channel.
