[TowerTalk] Rigging to access feed point on boom 10 feet from tower

[john at kk9a.com]

I have made on the tower large Yagi adjustments and repairs completely  
myself by supporting the antenna with rope, unbolting it and then  
rotating the area needing work into a position reachable on the tower.  
  Lower antennas are easier because you can attach the rope higher to  
get more boom movement and you can reach the are by either climbing up  
or down depending which is easier.  If you choose to do this, take  
your time and work smart and safely.

I have need to access a feed point on a 4" diameter boom, about 10 feet
away from the tower.  I know I can "PVRC mount" to tilt and rotate it
close to the tower, but this antenna is a monster - Force 12 C-51 XR,
16-elements, 51 foot boom, weighing 250 pounds, so I'd rather not go
that route and risk creating other problems.

Tower is 120 feet of Rohn 55G, guyed at 118, 77, and 37.  This antenna
is at 52 feet above ground.  It can be reached by aerial lift/bucket
truck, but not inexpensively.

The feed point is the driven element of the 40 meter section.  Between
the tower and the 40m DE are the 15m and 20m reflectors of those
section.

I do climb; I'd like to hear/see some ideas to SAFELY rig to go out to
it myself.
