Default Tri-Ex vs US Towers

Thanks for your response. I live out in the country and own the
property all around the tower site with the closest neighbors
appoximately 1/2 mile away so I am not worried about the tower falling
on somebody but I am concerned about the overall robustness of the
mount. I looked at the different webites and it looked like us towers
had a larger footprint for the concrete pad than was speched out at
tashtowers. I just wonder if it is way overkill for my application
since the are building these bases for their own (ustowers) design. Any
thoughts?


Each tower engineering design and recommendation is based upon a set of
assumptions about soils, drainage, tower stresses and wind loads.

The "size of the concrete footprint" is the engineer's design based upon
these assumptions ... I would not venture into guessing what these criteria
were --
I would ASK each vendor.
I think you will find that their assumptions are different and all you are
seeing is the physical changes required based upon those assumptions..

Also, I would ask US Tower, before purchase, about using their base on your
TriEx Tower .... you are "mixing" designs.

I would desire to get a "sign-off' by their engineer for such a
substitution.

I understand your rural, no neighbors situation - BUT it can fall on your
house.
Towers are of little resale value without the supporting engineering
paperwork.
