Ok I suggest a Winegard HD7082P antenna with a Winegard HDP269 preamp , mounted on the roof. . Replace the distribution amp. with a Simple 3 way Splitter. . Direct the antenna at about 216 magnetic compass. The channels to receive are the Digital Channels. If any of the analog channels are received then Ok , if not then Ok. . KCXW 5 The CW is very strong station and might be received with this one antenna. . If not , and you will like to receive it then I recommend a Simple Non-Amplified indoor antenna directed at channel 5 and a Remote Control A/B Antenna Switch from Radio Shack at the Tv locations that will like to receive channel 5 , so as to switch between the outside antenna and inside antenna. Here is how to aim Tv antennas ,
