  the particular tower is around the bottom in close proximity to a building, at 75m contour.  getting me to this location were several sites with text from over the years found by a search for `wxpn roxborough antenna', but i have no idea if the osm data is up-to-date - kinda hard to keep track of all the changes over the years described in the found websites when my present interest lies elsewhere at some 917m where perhaps a more compact collection of bristles can be seen from near sea level.  must do a count sometime and verify osm's mapping.
  
  the tower name should be the Gross Tower.
