[TowerTalk] Rohn 45

Merry Xmas
My idea can be cut the R25 legs about 23 inch from the concrete
later  Weld or  bolt some thick steel angles like  3/8   or 5/16  where I can 
attach some 1/2 inch  long bolts  to joint the  flat base of R45 
like the ones you can buy on HD or Lowes with the epoxy
the angles need to be welded together  and  adding some extra bolts
with epoxy to the concrete pad can be an extra security
I will do both to be safe
But if you have no experience hire a guy who can cut, make and  weld the base
and can drill the holes  and place those extra bolts correctly with the epoxy.

but is possible going that way  if  the cost is not the correct for you
check removing that concrete  and adding a new one with a short R45 base
sometimes can be  better for mind rest
I made 3 Installations using  2 and 3 R45 sections   up and one half poured in concrete
to install some WIFI equipment and are very solid

Check your options and cost, select what give you more peace of mind

I want to remove a Rohn 25 that I have buried in the cement. I want to reuse the  concrete base and attach Rohn 45 in its place. I want to install about 28 feet of Rohn 45 with a small 6 meter array,4 antenna but only 5 elements each. The antenna  box will be about 24 feet by 24 feet. There will be about 18 square feet of wind load on the tower. Is this possible? Should I did out the base and plant the 45 in the hole and re-cement? Can holes be drilled down into the concrete and a base plate used for 45 be attached using bolts and some type of epoxy?
