At9 Antenna info please?

[JackR]

Have ordered the H20 receiver from DirecTV. They will install the new AT9 antenna next week. The mounting post rail on my deck is 5 inches wide. Made up of one 4X4 post plus a 2X4 post nail together. I needed that width for the older 3 LNB antenna mounting pad bolt holes to fit. My question is, will the current 5 inch width be enough for the new AT9 antenna bolt holes. Plus, what about supporting brace foot print?
Should I lag bolt another 4X4 or 2X4 to the existing 5 inch width?
Any information will be appreciated.

The most important thing is to make sure whatever you mount to is solid. It should be wide enough but just make sure like I said it is solid enough if you hit it with your truck it will not move.
