Doesn't matter if the radiation pattern changes, if you can still receive
the signal you still know the direction.

Ok, I didn't make myself very clear there. In my area, the radio stations
have agreements to share their towers, and to carry multiple transmitters.
After a lightning strike, one local station lost everything, but 6 hours
later, they were back on the air from a neighbours tower. Not very handy if
you happen to be DF'ing the wrong location! NOTAMS are not required for
Commercial Broadcasters, so it could be a disaster for the uninformed.
