I recommend a Winegard HD7698P antenna with a Winegard AP8700 preamp aimed at about 195 true - 187 degree magnetic compass. The antenna and preamp will be mounted outside and will be 20 to 25 feet high , about as high as a 2 story house. The antenna and preamp Will Not be connected to your other antenna. Do Not connect the two antennas together. The RG-6 coax of the HD7698P and AP8700 preamp will go the the location of the Tv. At the location of the Tv there will be a remote control A/B antenna switch , a AB27RS or radio shack 15-1968. Here are places to buy Tv antennas and etc. ,
