 last night trying to understand how whatever the crane
 operator uses to pull the mast up 15 feet above the tower
 top would be disconnected!!  Seems somehow someone
 would have to get up there to unhook something.  Also,
 how does a crane connect to a 2" diameter pipe and pull
 it up?  >>

        Good question. The *best* method is to use a sewn nylon loop sling as 
a choker. You wind it around the mast (or any other irregularly shaped 
object) and pull the end through the loop. You hook your hook, carabiner, 
etc. to the loop and pull away. The sling works like one of those chineses 
finger puzzles - the harder you pull, the tighter it gets. This method is 
simple, safe and goes on in a couple of seconds. You can put a muffler clamp 
above it as a safety stop but I've never seen one move.

      Of course the slings are available from Champion Radio Products. These, 
along with carabiners, are a tower worker's best friends.
