Your reception location is Not simple. The tv networks are spread around 3 directions. The strength of the tv signals range from very strong to Very Weak. I do not recommend using any type or kind of amplifier. The strong signals will overload the amplifier resulting in bad reception. I do not recommend putting the antenna in the attic , the weak signals will not be received. What I do recommend is a outside roof top antenna , a Winegard HD7697P antenna mounted on a ChannelMaster CM9521A rotor , Mounted on the roof of the house. Here are some antenna mounts ,
