There are several ways of looking at a terrain profile beween a transmitter and his location.

If you click on the rabbitears.info report for his location
https://www.rabbitears.info/searchma...&study_id=4518

and then click on the Transmitter Distance (Miles) for a channel, a profile for that channel will come up. This is what the WPXJ terrain profile looks like. The red line is the direct signal path blocked by terrain; the blue line is the probable signal path.



There is a profile available from TVFool, but it is no longer correct because the WPXJ transmitter moved when it changed real channels from 23 to 24:

This is the WPXJ profile using other software:
