There is a tree partially in the way. There are no big buildings, at least tall ones, that I am aware of. There is O'Hare to the north of my LOS and Midway to the south.
Is there any way to tell if I really am experiencing multipath, versus just losing signal strength because of the attic?
I searched Winegard's website in order to find out more.

"The average gain for the HD7210P antenna is -3dB on channels 2-6, +5.5dB on channels 7-13 and +8dB on channels 14-69."
The gain is less than some of their other antennas such as the 7697 or 7698. Is this an area of concern? IOW would the benefit of ghost reducing outweigh any potential loss in gain?
