[TowerTalk] Rohn 25 Guying

[J. Hunt]

It is very discouraged to anchor any tower to a tree.

No manufacture or city code would approve of that method.

I have witnessed catastrophic tower failures of trees uprooting and / or leaning.  Each case, the tower and antennas ended up as scrap metal.

The proper method of anchoring any tower is by guy anchors or posts buried to the proper depth (dependent on soil make-up).

My tower is anchored by 6" schedule 80 posts, buried >7' deep x >3' diameter concrete back-fill with re-bar.  Soil composition is ~2.5' soil, remainder solid rock.
It was very difficult drilling / jack-hammering punching through the rock, each hole was belled out at the bottom.
 

Merry Christmas / Thanks n 73,
James

 Has anyone used trees as guy anchors for a 50' Rohn 25 tower?
 
 If so what was your method of attachment?
 
 Thanks
