You want side support arms to hold the LNB in place?
Not a problem. Do it.
There are pictures on the forum where others have.
I had a big heavy LNB, so I put
larger supports on mine.
You want to stabilize the pole the dish sits on?
Some dishes come with such support struts.
There, you need to drill holes in the vertical tube the dish sits on.
Maybe not what you asked, but it's no problem. Do that , too.
There are pictures on various vendor sites with good example pictures.
