The one I sent a picture of is a water storage tank. 100' concrete
pedestal with a steel tank on top.

Are those Harvestores or similar? Isn’t the silage inside a

The problem with this type of tank is that the railing itself isn't
stiff enough to mount anything without creating another structure
entirely to brace the railings. The railings literally move about 4
inches under about 20lbs of pressure. The railings meet the absolute
minimum required to comply with OSHA, and even that is a bit doubtful.

a UPC1 from sitepro. put a pipe inside the angle of the upright to
give you something to bite into for the clamps.
That doesnt look all that stable so you might need to run a
stabilizer bar off. thats what we have done, no pics though.
34db im guessing is 3' or more, so I dont know that this would have
enough beef for that

This is probably the best picture I have of what we did with one
of those silos. Your silo looks identical to the one we are on:
The railing, as you noticed, is very wobbly. At the base of the
vertical unistrut are L brackets. We took one nut off the top of
the tank and secured the bottom of the L to the stud. The two
unistrut cross bars were mostly to give us a mount for the 900
omni, but they also serve to stiffen the structure side to
side. You may want to run more of those on diagonals to further
stiffen it. Front to back stiffness is provided by the threaded
rods that you can just make out in the foreground on the right
side of the picture. The threaded rods pull in on the railings
while the unistrut keeps the 'circle' of the handrail from
collapsing inward. The overall assembly is reasonably stiff for
the load we have on it. For a bigger dish you may want to
substitute something stiffer than the threaded rod front/back.
Adding a cross brace between the walkway rails would help stiffen
the entire assembly but would block the walkway and might be
politically unacceptable.

Anyone want to share pictures of mounts on the top of silos?
The railing is not super solid and we need a 34db dish on top
there. We should be able to remove two bolts from the seams and
install a metal plate for a U-bolt to solidify the bottom, and
U-bolt to the rail at the top. That would be plenty solid for
sectors, but debating bringing back some sort of bracing arms
for the BH mount.
I know many of you have sites on top of silos. Anyone willing
to share mounting methods and techniques and/or pictures?
