An antenna above 20 feet is nice to extend Line of Sight (LOS). Google maps can help with an overhead line to a transmit site. This can help orient the antenna around obstructions. Vertical 90 degree to horizon for FM phasing. https://www.google.com/maps/@39.3347605,-76.5804327,43637m/data=!3m1!1e3!5m1!1e1
