text: the wikipædia value looks to be derived from the fcc database HAAT value seen at https://transition.fcc.gov/fcc-bin/tvq?call=WQED which is different from the actual mast/tower height (it's a mast, not a tower, right?)
  
  i'm assuming i don't need to explain the HAAT meaning.
  
  said fcc page gives the overall structure height as 181,1m, giving up to 20m vertical for the array, which seems reasonable enough, unless one of the other call-sign frequencies operates at a higher centre on the mast.  the fcc link to the tower appears to lack the info i find at the bundesnetzagentur when multiple operators use the same facility, unless there is a single antenna in use here, difficult to believe, but i digress.
