RF is a surprising beast--best not to underestimate it.  As the joke
goes from an RF guy I worked with once, "FM doesn't stand for
frequency modulation.  It actually stands for 'f#$@in magic.'  Even we
folks with our EE degrees have to admit we dont' fully understand how
it works all the time."

So, let me gently add to the others who've suggested please please
dont' screw with the safety of aviation in your area for want of
another $100 worth of capture card and a passive co-ax switch box. 

Passive co-ax switch which even has a remote control for $50 

$15 passive high isolation co-ax switch:

Please do not combine CATV and OTA signals in any way shape or form.
The results won't be what you want, and you will be spewing RF noise
into the area that'll at the very least cause interference with TV
reception among your neighbors, and at worst, will interfere with the
safety of aircraft.
