And the reason 'GBH has to move for this to work is that WGBH is on RF
channel 19, and WCVB is on RF 20; the combiner system can't provide
enough isolation to run first-adjacent channels off the same antenna.
(That's why there are two broadband UHF antennas in the first place --
this was an issue during the transition as well, with WGBX on analog
44 and digital 43.)

And of course once the repacking happens all of this is going to
change again, at great expense, and some broadcasters are probably
going to decide it's just not worth it.
