Hello Steve,
I suggest you ask around your local radio club. Someone must have access to
a surveyor transit and that knows how to set on up and use it. They should
be able to visit your QTH and make certain your towers are straight.
It is a simple process to shoot the tower with a transit at the two proper
points. This way you will know for sure what guy wires need to be adjusted
to get your towers perfectly straight. Make certain the guy wires are
properly tensioned according to the tower manufacture's design instructions
once the tower is straight.

Subject: [TowerTalk] misaligned vertical towers
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.
