That's an "undereave" mount, and in my area, they are almost required on most new-construction homes, as the walls are styrofoam-stucco, roofs are cement tile, and houses are too close together for pole mounts. As long as you have the two support arms in place, you should have no problem.*
*I'll mention one exception: DirecTV wanted to supply similar mounts to techs for free, because they didn't want techs charging money for these custom mounts (which techs have to buy). So, they bought some cheap copies. Well, the low price came at a price: low quality metal and low quality welds. When a big storm came through, a bunch of the mounts failed. Now, DirecTV doesn't want undereave mounts to be used. Never will they admit that the problem was the junky examples that they bought, as opposed to the design in general.
My company has installed over 300 of these mounts and never had a single problem, but the ones we buy are made locally from good materials, and they cost more. No surprise: you get what you pay for.
