Wilson's 301121 Ceiling Mount Antenna, says a retailer, 'sprays down' the amplified signal to, basically, one room. The Wilson 301135 wall mounted Panel Antenna sends its signal directionally - 'down a hallway to the rooms at the end' says the retailer. Sound correct to you? My 1700 sq ft house is essentially an L shape, with the office computer and exterior antenna feed located at the intersection of that L. Q: Which antenna....and Where should I place it for best coverage. Looks to me like there is no way to cover the entire house... Thanks!
