You're report includes the warning "
Address was only resolved to street level and might not be that close to your actual location. For more accurate results, try entering a specific address or coordinates."
You can create a more accurate report by using the
Interactive TV Maps tool. Looking at the area based on the ZIP code, the terrain may affect the signal prediction significantly.
Based on the information thus far, a Winegard HD7698P and Antennas Direct CPA-18 preamp would be an option. I would also try to find a way to safely mount higher. If you generate a new report, you can try using different AGL values to see what, if any, improvement in signal levels can be had.
