Sprint's new 4G LTE network cabinet (foreground, with door open), followed by the Sprint gear it is replacing and, furthest away, a rival carrier's gear.
One of several antennas Sprint has on the roof, painted to at least somewhat blend in with the building.

It's a view that homeowners would pay a small fortune for. Cellphone carriers also pay dearly, though few people ever see the view from the rooftops that house their network gear.

Some of the many warning signs that let those who go on to the roof know that they are likely to get more than a bit of radiation.
I think "Happy Fun Ball" had fewer warnings.
Cellphone companies pay a pretty penny in order for their towers to have a view like this. Landlords often get thousands or tens of thousands of dollars per month for opening up their buildings to the carriers -- in some cases making more from the rooftop gear than from tenants inside the buildings.
