Back in the day, people would put these up for home CB antennas. Bunch of people would all show up to help out, it was like the Amish raising a pole barn, except with a ton of beer. Somebody would bring a power auger to dig the hole, someone would have a wheelbarrow, people brought shovels. Garden hose to mix the quickcrete in the wheelbarrow and up she goes.

I don't recall ever seeing any safety harnesses, either. Ah, the 1970s.
