The Antenna Wall Mount is easy to install. Setup is pretty easy for wood siding with lag bolts. It also comes with expansion bolts for concrete. You will get a 3-legged mount, plus a 2-legged mount (same gauge hardware as the three-legged). And note that the 3-legged one at the bottom.
Kit includes: 1 pair(2-leg and 3-leg mount braces), including U-Bolt, V-Block Brackets, M8*60mm expansion bolts and lag bolts for reli mount.
