[TowerTalk] Mast Steps

[john at kk9a.com]

I have similar sized antennas plus a very heavy medium prop pitch rotator.
 Removing the rotator, loosening the bottom antenna and boom truss,
jacking the mast down and back up, then re-installing, lining up the
antennas and setting them to true north would be a considerable job.

I have a similar situation.   The problem for me is that I have big stuff.
The antenna just above the top of the tower is a 6 el 20m beam that weighs
well
over 200lbs (60 foot boom).    Pulling an Orion rotor out of AB-105 is no
small
task either.   I had to climb the mast to fix a 15m beam that spun in the
wind.
  The pucker factor is way high and if you don't manage your lanyards
right you
could wind up in deep shit real fast.  Not good at 160 feet.
