Ok, I think we have a clue then... The square tubing likely isn't bent, but the stamped angle where it connects to the mount is the most vulnerable point after the plastic LNB adapter. To throw the elevation off by 7.5 degrees would only need a bend half that and wouldn't be readily noticeable. And yes, your best bet for now is to just allow for it when setting up.
Oh, and when water is readily available, I anchor my tripod with a 1/2 to 3/4 full 5 gallon bucket suspended from a tie down strap. It's never blown over in with 60 MPH gusts. Otherwise I use two "dog tie" screw anchors.
Most of the time I put a screw down doggie stake under it. However, this is one of those "keep off the grass" places (I think the most upscale we've ever been in). I have a 5 gal bucket under it, but it didn't hold up when we got hit with a big wind gust and blew over. I added a couple of concrete half blocks and, really, wish I had a bit more. Had up to 40 mph gusts today and more expected as a front comes through overnight.
I spread the legs out a bit more today and then added chain stabilizers to hold the legs in there.
Who knows, if it blows over again it might straighten out the supposedly bent arm.
