I believe your talking about Monopoles that hold the cell antennas. A whole
than the light pole. You are correct when you say a massive mat and pier or
The company I work for has a little over 1000 Monopoles, SSV, and guyed
towers in Florida
alone. Monopoles are a pain in the butt. They don't have the structural
capability of the
other two. You run out of room fast on the inside running coax ect.

There's a lumber yard in town that has something similar supporting a passel
of cell phone antennas. Like above the pier or caisson is massive and DEEP.
They don't even wiggle in 70 MPH gusts. The one I'm thinking of was limited
to either 160 or 180 feet due to proximity to the airport, but gives good
coverage city wide. Of course if you fly you find these things are like
fleas on a dog. In this flatland towers vary normally between 250 to near
500 feet. Except for the city it's low population density (relatively) and
the towers are spread out quite a ways so they tend toward the taller ones.
Most are conventional guyed or large self supporting structures.
