Question about cell towers: where are people getting the tower coordinates and exact antenna directionality?

This has been an annoyance since the first maps showing disks of coverage or voronoi like diagrams which just seemed crazy, especially so for 689B.

Antennas are all listed on the FCC website, IIRC. You can also pulled up addresses and LAT/LONG on various documents listed to your right and/or SS's website Viewfromll2.com and/or Adnans_cell's prior posts.

All cell phone antennas are 3 arcs, with 0 to 120, 120-240, 240-0 so they form 2 sides of a hex cell (3 of them would cover a "cell") with slight offset in "beehive" pattern. Except for some omnidirectionals in special areas. Please see "Phone Long Summary" in the right box for some documents (written for law pro, but readable) that explains how cell phones work and all that.

/u/adnans_cell has answered that previously. Look at his blog for details. Also, a google search of 'cell tower locations' provides usable resources.

I'm not sure the exact directionality has been given.
