The tvfool radar plot report shows the antenna height at 25 feet , thats Ok , however if the antenna were higher the many weak tv transmissions will most likely be stronger.
Make 2 more tvfool radar plot reports with antenna heights at 40 and 60 feet.
Is the antenna mounted at about 25 feet high??
Any big trees or structures that can reduce or block reception to the east/south/east??
Is the antenna aimed at about 115 degree magnetic compass.
