BTW, people talk about Muzack in fast food restaurants. Never saw a fast
food restaurant with Muzack. It is something else.

As a former Muzak installer, I can assure you, they do.


I'm still skeptical on the idea that most noise is either vertical or
horizontal, and that rotating an antenna 45 deg will cut both by 3dB

Also, this would be an FM service, where such noise would normally be
insignificant.
