The MWB-220 includes the same radio as the MWB-200, but has a built-in 90-degree directional antenna. Because it concentrates its signal on a smaller area, the MWB-220 delivers more than twice the effective power. This design is superior in a marina, because your vessel is in a relatively fixed position and you usually know where the nearest access point is located.
