[TowerTalk] H-beam for elevated guy

[Jack Taylor]

Depends on soil composition.  Here in the Aridzona high desert country our 
soil is packed like cement.
Thus the depth of the anchor hole doesn't need to be as much as with looser 
earth.  In my case I found
the local power company had an economical 30 ft. treated pole which I cut 
into thirds.  They also had
the necessary hardware for guy attachment.

Steve,, I just put in an elevated anchor for 151 ft of 45 with a LOT of
loading for antenna.....
I twisted in a 30 inch hole with an auger from a Bobcat attachment. This
hole was 6 ft deep. I poured 3000 mix concrete up to the top.  I went to a
local scrapyard, and found a huge I beam. It is 18 inch X 10 inch and 1/2
inch
thick.,, and 12 ft long.   6 feet is in hole, 6 feet up.
The "I" is in line with the direction of the load-which is the guy
wires....I have the tower guyed at 38 feet, 76, 114,
and 144.   I thought I may have to back guy this beam,, but it is SOLID,, I
have the guys pulled quite tight. I am not back guying it at all..The key
thing here is go with extreme overkill. If you put in an elevated anchor,,
MAKE SURE its way too big, and you will have assurance of the installation,
and know there is not a weak link in the anchor.   Another time,, I used a
section of railroad track,, its ungodly heavy,,, but it does not budge
either...Good Luck....Dan N4GNR
