I recommend a Winegard HD7084P antenna and a Channelmaster CM3414 four way distribution amplifier. Mount the antenna on the roof with a Strong and Strudy antenna mount such as , tripod mount , chimney mount , peak of the roof eave mount. Put the 4 way distribution amplifier where it's protected from the weather. .
