The tower installation Steve was referring to in the first post indeed
required >25 cubic yards of concrete. I know because it's my tower that
he's referring to.
The PE who did the calculations for my HD-60 was the PE AN Wireless
referred me to. I believe that this PE firm is also the firm that
originally designed the AN Wireless towers. The resulting plans called for
a 11' x 11' x 6' base.
The rebar cage was also quite complex. See the photo in the link below for
a photo of the rebar work before the concrete was poured.

## and here I thought my re-bar cage + 17 yards was nuts for my UST HDX-689.
Your 11 x 11 x 6 = 26.9 yards = 54 tons of concrete. Maybe your engineer
did not like
the loamy soil ? IMO, it would not have gone anywhere with the prescribed AN
10 x 10 x 5 base... they already spec for sandy soil conditions.
## But I have seen this before with several tower bases where engineers are
involved.
It seems that no matter how much concrete the tower maker sez to use, the Peng
you hire
will always add just a bit more, make the hole a bit wider..make the hole a bit
deeper,
add some more re-bar into the mix..... then spec slightly stronger concrete.
Then when he is all
done, he looks like a superstar to the folks down at city hall..... who will
then tell joe ham,
why hams need both the...’benefit of a building permit’.... and the prescribed
use of a Peng.
## but hams have no choice in the matter. Too bad, you pay for the Peng, then
you pay for more
concrete / bigger hole etc. If the wind blows hard enough, the tower will
fold over aprx 2/3
the way up the tower....and not at the base....that’s typically how self
support towers are designed.
Both trylon + UST do the same thing.
## forget all that, the AN product is miles ahead, and cheaper than the light
duty Trylon, hands down, so
at least you bought the real deal.
