I want to level my new US Tower HDX-589.  I put a 4' carpenter's level on 
all three legs of the base section and have levelled them.  This is all US 
Tower recommends.

Is there anything more I can do?  I have heard of using two theodolytes with

it fully extended.  But I figure the sections must lean a bit due to the 
clearances that allow them to slide past each other.  I don't want to tilt 
the bottom section to compensate for that lean, since different antenna 
loads or wind loads will probably make it lean different directions.

With the bottom section leveled, am I done?


## I'd level the base the best you can do with a digital level.   On the HDX-689
base, I used the 3 x vertical riser's.  Once tower is installed onto the base
[fully nested of course], then  install the MAGNETIC, DIGITAL LEVEL 
at the top of the bottom the 17'-21'  point.  Those things are 
cheap enough,
I have seen folks  use 3 of them, one per leg.  Then, if required, tweak the 
leveling nuts
on the tower base.   Use a  ladder or binocs to see the display[S] on the 

##  That procedure makes leveling the tower a lot easier.  when it's  dead 
level at the
17-21' point of the bottom section.... that's as good as it gets.
