With the very light antenna load I don't see any issues. Certainly if
a tree falls over there might be so would it be so if it was guyed to
ground anchor points and a nearby tree still fell on it. I think you
guys are making a mountain out of a mole hill.


I suppose also if a Boeing 747 crash-landed in this guys yard there
would be an issue as well..but come on guys...this is no big deal so
let's be practical. Frankly I've seen a lot worse and they have been
up for years. And, moreover, if everyone erected strictly according to
Rohn standards few of us could afford a simple 50 footer!



You apparently have little understanding of safe tower installation
requirements, regardless of factory specs. This isn't a simple 50 foot
installation... its a 90 foot tower, and when it comes down, its going to
have a big effect on the neighbors. The wind loading of that tower
preempts any problems with antenna loading. Given the poor base, and
especially the lousey guying supports, its an accident waiting to happen.

Thanks for saying it. Three four-foot deep lumps of concrete are not a
sufficient anchor for a load like that. I gather there's a bit of wind every
so often in MI? Those feet will pop out like corks.

Here's some guys who thought it through a little better:

This data is for self-supporting towers but it's interesting to note:

This is sorta relevant (it's a much bigger tower but is just plain neat:

I mean, sure, we've all put up a dodgy 'tower' (I think my biggest self-made
piece of crap was maybe 8 metres high, and at least I was the only one hurt
during removal!), but this is serious ****, it could easily kill people when
it comes down. When, not if.

With this being a guyed tower I find it hard to believe that the feet
will come out of the ground or do anything but sink farther into the
ground do to the weight of the tower and the soft soil.

I put up a temporary tower in 1978 that is still standing. It is 50
foot high and is sitting right on the ground (about 8 inches in now). I
have two sets of guy wires. I have 4 ants on it one being a 42 foot 20
Meter KLM. Also one leg is tied to a tree and one tied to an anchor in
the roof of my wife's shop. The third in tied to two posts that are
driven in the ground about 3 foot.

Now remember this was my temporary install of almost 30 years ago.
Someday soon I am expecting to make it more permanent but.......
