Guidelines When Asking for Help
Because the terrain in the area appears to be relatively level, I don't anticipate a significant change in signal conditions between locations along Colonel Leonard Rd. So here is a link to a report for the general vicinity.

The signal conditions indicate that a mid-sized antenna such as a Winegard HD7694P aimed due west would provide coverage of both Baltimore and DC signals.
How many TVs do you plan to connect?
How long will the coax be if run from the antenna to the most distant TV?
