The Ebright Azimuth is the point with the highest benchmark monument elevation in the U.S. state of Delaware. It is marked with a geodetic benchmark monument and has an elevation of above sea level. The only state high-point with a lower elevation is Britton Hill in the state of Florida at above sea level.
Description
The Ebright Azimuth is located about north of downtown Wilmington, Delaware, in far northern New Castle County, approximately 500' horizontal distance from the Delaware-Pennsylvania border. It is near Concord High School, to the north of Naamans Road, at the middle of the intersection of Ebright Road and Ramblewood Drive. This is an entrance to the Dartmouth Woods neighborhood.
Surveying by Delaware Geological Survey personnel indicates that the mobile home park just west of Ebright Road is at least higher than the benchmark.
Ebright Azimuth is named after James and Grant Ebright, who owned the property on which the benchmark was placed.
Western Union's engineers specified a heavy-duty prefabricated fire tower structure, which allowed the microwave transmitters and receivers to be installed inside the cab. "Dish" antennas, mounted behind the window openings, were aimed towards the adjacent relay stations at Mt. Laurel, New Jersey, to the northeast, and Elk Neck near Elkton, Maryland, to the southwest.
Like most of their early microwave relay sites, Western Union decommissioned the Brandywine installation near Ebright Azimuth as more-reliable broadband fiber systems were developed. The structure now supports several VHF and UHF land mobile radio antennas.
