Sounds like 1-7/8" SCH 80 pipe.

Yeah, it’s a legitimate concern. They sway a little, but nothing that
affects it more than a few Db. This is a 24’ x 1.9” we order from a
pipe company. It’s got some rigidity to it, with a .095” wall. It
weighs in at about 1.83 lbs per 1’. The key is getting that first 4’
to 5’ attached to something solid. As a note, this or a grid would be
at the upper end of what we would want to install on it, as far as
wind load is concerned. But with a clip on a 450, or a yagi on a 900,
very little concern with wind load, and it’s a great option for a post
in the yard, hip roof from the ground up, or a tower install, as seen
in the attached image.

I was just asking because once we get over 10-12 feet with a pipe,
there seems to be quite a bit of bobbing around if there’s significant
windload at the top. Not so much a problem side-to-side, but
front-to-back affects the dish aiming. Usually at 24 feet, we would
be recommending a utility pole or a Rohn 25G.
Also a lot of our area, the wind seems to howl 11 months out of the
year (except August when you actually wish for a breeze), and we have
trouble with metal fatigue and bolts vibrating loose.
Microbursts are also a problem, it will lay the corn down like a crop
circle, and rip the siding off houses.
I know this is partly because we have open cropland where the the wind
can blow for miles, also some ridges which are very exposed. You know
there’s wind when people come to build wind farms by you. It looks
like you have trees, so maybe that slows the wind down a bit.

The pipe? You’d be surprised, they do pretty good in winds, we install
those on a TV tower too. We use a PD46 HD bracket, with 4’ attached
to the tower, and the remaining 20’ in the air. We can get 40 to 50
MPH Gusts in storms here, and have had very few fail. The only time
I’ve had any fail, it’s usually the brackets twist on the tower, and
that’s tornado weather, and extremely rare. We’ve installed hundreds
of these, and maybe had less than a handful need fixed. As far as the
radio/antenna, those don’t mind the wind much, I’d say an old
Hyperlink 24 Dbi Grid is more wind sensitive than that, or at least a
close comparison.

What kind of winds can that withstand?
