[TowerTalk] misaligned vertical towers

[john at kk9a.com]

Probably neither are vertical.  The Loos tension meter does nothing to make 
them plumb and you can only see if it is straight looking up from the 
bottom.  I use a transit level.  It is easy to use and very accurate.

I have two towers up.  A 90 foot Rohn 45 with a 6-el 20 meter beam on it and
a 102 foot Rohn 25 without anything on it yet.  Both are guyed.  In putting
them up, a group of us used a Loos tension meter and our eyesight at the
bottom of each tower to make them vertical.


But when I look and align the two towers next to each other by walking 
around until they are "next" to
each other, one or both are off vertically with respect to each other.


How do I figure which is straight and which is off or maybe both are slight 
off?
I really don't want to climb them now in the bad weather and drop a plumb
bob and do not have a survey level.  They are really 135 feet apart.
