CommDeck- extra bracing needed?

    I had a CommDeck installed on the house that I am moving into (new construction) and also ordered the strut clips just in case. My install is later this week. Is extra bracing needed with a CommDeck? I would think that the CommDeck provides a very sturdy mount for the dish.

    More bracing is never a bad thing.

    The CommDeck has a pretty large base to distribute the leverage from the mast, plus you'll have support arms (monopoles) to help. Unless you live in a place with lots of high winds (and probably even then), you'll be fine. But, as Robert noted, a little extra never hurts.

    Every time I mount on the roof or use a commdeck, or a retrodeck, I use 2 monopoles. A pair of strut clips = 2 monopoles.

    I see it as the less holes in a roof the better.

    I did one where the roof was being reshingled as we worked. The roofer was on site and had a standard 2" roofing through-deck flange. I drilled out from the attic and pushed the 2" mast up through the hole. bolting the mast to a roof truss inside the building. Then the flange went on and then they shingled around it.

    The cable went down the mast to a nearby corner, out again and down the back of the gutter drain to the ground block & cable entrance.

    Looked good with no leaks. Just a thought.

    I installed a Commdeck on my roof a few years ago in anticipation of my Slimline Install. I also purchased the strut clips. The installer used 2 monopoles and the clips. He said that it was his favorite installation to date.

    The dish is rock-solid. It did not move at all during the wind storms we had (gusts to 70+ mph).

    Use struts. Commdeck isn't really all that heavy gauge metal and will flex a bit.

    I installed a big AT9 ("sidecar") dish using Commdeck and the strut clips a couple of years ago, and it has been rock solid ever since then; signal levels haven't dropped a bit (i.e., alignment has remained true). And that's after a few pretty good Kansas storms (including a likely funnel that passed right over a few months ago that took down a big tree).

    See [post=1424297]my post on this topic from earlier this year[/post] or my (somewhat entertaining?!) writeup "DirecTV Dish Installation Project" for more details.
