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. From: Ben Royer Sent: Tuesday, February 02, 2016 11:14 AM To: af@afmug.com Subject: Re: [AFMUG] First Force 200 5 GHz! 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.
