What is it that makes a standalone tower stand alone?  without guys?  I have 
a used Heights tapered aluminum tower which I am going to install sort of 
close to the shack to put my Vhf/Uhf yagis on to minimize feedline length. 
Is it because the taper makes the shape sort of triangular which, I bet, is 
the most stable of geometric shapes (compared to a Rohn 25-45, etc. which 
all sections are non-tapered)?

Would I affect anything by adding a set of guys so I don't panic as much 
when I climb it to install the sections and then the rotator and yagis? 
Even though the hole in the ground holding the three long bolts would be 
about 7 feet deep by  4 feet wide, minimizing movement is an objective while 
I am up there.  I was thinking of three  Phillystran guys that I connect to 
ground anchors when I am on the tower and then either removing them from the 
ground anchors for operation or keeping them on for extra stability.

This Heights tower is going to be 60 feet tall although it originally was 
112 tall.  A friend topped it off later at 60 feet with a new flat plate so 
he it would not interfere with his astrophotography in his yard.
