If the hospital intercom produces that much interference to licensed services I'm sure the FCC would have dealt with them long ago. The cable company sounds worse than most.

Aircraft make excellent signal reflectors. It's possible that nearby aircraft could cause a form of multipath interference. The four bay antennas achieve gain by concentrating the vertical beam width close to the horizon which reduces the chance that signals reflected from high angles will cause a problem.
