Satellite Dish on NW Tower of Lightner Building and City Hall

Visible from the Lightner Museum and City Hall courtyard on November 30, 2014 was an ugly satellite dish. City Hall denizens have been loath to answer questions about it ever since.
It is ugly and mars a beautifully restored 1888 grand hotel that is our City Hall.
Who approved it? Why?
No documents exist, we are told.
Who put it there? Why?
Neither the City of St. Augustine nor its tenant, the Florida National Guard, will say.

You work for us, so tell us, please.
