230.28 says that "only power service-drop conductors shall be permitted to be attached to a service mast". But it didn't always say that. In 1990, there was no mention of that. In 1993 a FPN added that this was the intent of that section. Finally, the 1996 cycle got it right! I still see a lot of foreigh attachments to masts. I guess old habits die hard.
And look, no visible means of support!
Also, what happens when someone opens the door all the way?
