I would absolutely love a big writeup on how they're set up and what the components are, as well as all the real-estate stuff that certainly surrounds them. I'm also noticing a lot of new towers that look like big cylinders on a pole, sort of like a TACAN so I often wonder what's up with that.

I do know that the traditional ones are triangle shaped such that they each form the intersection of a hexagon tessellation (hence the cell in cellphone) such that you have three towers pointed into every hexagonal cell.
