I'm sure that would be considered a less-than-ideal plan, not because
of potential interference issues, but because 120vAC  should have its
own conduit.  Running "high" voltage in the same place as low voltage
would not only fail inspection (rightly so), but it really isn't safe.  If
there was a problem, you really wouldn't want 120v getting into your
rotor line or your camera, or especially your coax.

Use the same trench if you want, but give the 120v stuff its own
1/2" or 3/4" grey electrical PVC.  (It really is supposed to be buried
3 (?) feet, I think, but that is to keep it safe from digging.)  The PVC
is cheap, and you'll be glad you did it.  And if you really do have to 
dig another trench, also put in another 2" or 3" empty PVC for future
coax/rotor runs :-).
