Based on the limited data present in the plot, your location is one that appears to have Philly, NYC, and Albany as potential targets. Two out of three would require a very large all-channel antenna with a preamp. Your simplest solution would be one of those antennas on a heavy duty rotor. Your final choice would depend on whether or not you desire reception of all three markets when compared to the actual available signal paths as seen from your potential mounting locations. You may have to base your choice on that terminal signal path.
