How much does the average cell tower cost?

I'm curious to know, what's the estimated cost of constructing an average cell tower? Are there any significant factors that can influence the final price tag? For instance, does the location, height, or the technology used play a role in determining the cost? And how does this compare to the cost of maintaining and operating such a tower over its lifetime? I'd appreciate it if you could elaborate on the financial aspects of building and managing a cell tower.
