[TowerTalk] Rohn 25G (Pier Base)

[Earl Morse]

The pier base is supposed to have that little bit of give at the bottom so if the tower twists in the wind (real tall towers) it doesn't fatigue where twisting tower meets immoveable concrete.  It's a little bit of a pain to erect but in the event that you move often you only have to get 3 new guy anchors and a pier pin to reinstall the tower.  Sure its a pain but then again how often do you install a tower in your lifetime.  I am on my third install and probably will be doing it again in the next couple of years.  Going to suck when I can't climb anymore.

>>I am wondering why you are using the pier base? I believe that unless you
are going really high it not necessary. In most installations that I have
heard or know of, the guys just bury a 4 - 5 ft piece of Rohn 26G in
concrete and build from there.

Isn't it easier to just use a flat roof mount, put some long bolts in when
you poor the cement foundation and make sure the top is level.   
The bolts will hold the base from shifting at the bottom and you are not
locked into a specific tower base.  It also costs a lot less.   
It's worked here on 120 ft of Rohn 45 for the last 25 years.
