>>2701541>and what type of companies do this sort of workThere's typically "tower companies", they're the guys who do the tower work. Hanging antennas, pulling feedlines, structural work (plumb/level, tension guy wires, load engineering).
And there's radio shops - they're the ones who design and spec the equipment and antennas, usually buy it but sub out the tower install service. Not a lot of shops do "full service" tower and site equipment work.
These companies are small. "Subcontractors subcontracting subcontractors" is the norm. They're names you've never heard before. Family businesses or small LLC's like I am.
If it's the tower stuff that interests you, might look at SBA, Crown Castle, and American Tower. They're big co's with big customers.
