[TowerTalk] Raising a mast on a tower with antennas still on it

[Leeson]

Please be sure to use redundant means of supporting the mast and 
antennas. There was an frightening accident a number of years ago when 
the bolts on a thrust bearing holding a mast snapped and it fell back 
down, trapping the climber by the hands. Don't let this happen to you! 
For example, use an extra muffler clamp or two on the mast at the tower 
top to secure it.
