    Here's how you do it. 

    Have UST ship you the base and anchor bolts right away. 

    Get a backhoe to dig your base hole. While he's digging, build the rebar 
cage. When he's done, he can pick up the rebar cage and drop it in the hole 
(it'll weigh a couple of hundred pounds). 

    Tie the anchor bolts to the rebar cage so that they'll be sticking up 
above the top of the form enough to mount the tower/fixture. Put a nut on 
each bolt - the fixture/base will sit on the nuts and these will let you 
level it. The anchor rods don't have to be perfectly plumb since you'll have 
levelling nuts under the base fixture. 

    Pour concrete. A line-pump will deliver concrete up to 400 feet if you've 
got a ways from the truck to the hole. 

    Now you're ready for tower arrival. Arrange to have a backhoe or 
boomtruck meet the tower delivery truck. You have to get it off the truck and 
then you need to move it into place. With the backhoe you'll need the raising 
fixture to get it vertical; the boomtruck can drop it vertically onto the 
anchor bolts/fixture. 

    Plumb the tower and tighten the base bolts. Use a non-shrink grout under 
the fixture. Not only is it in the drawings but it also provides more 
weight-bearing material under the base/fixture. The tower is designed to sit 
on the rod nuts AND the grout. You probably have to go to a masonry supply 
house to get the right stuff - the big box hardware stores don't necessarily 
have it. 

    Install antennas, etc. and have fun.
